I'm trying to run a find command for all JavaScript files, but how do I exclude a specific directory?
Here is the find code we're using.
for file in $(find . -name '*.js')
do java -jar config/yuicompressor-2.4.2.jar --type js $file -o $file

12 NextIf -prune doesn't work for you, this will:
find -name "*.js" -not -path "./directory/*"Caveat: requires traversing all of the unwanted directories.
40Use the -prune primary. For example, if you want to exclude ./misc:
find . -path ./misc -prune -o -name '*.txt' -printTo exclude multiple directories, OR them between parentheses.
find . -type d \( -path ./dir1 -o -path ./dir2 -o -path ./dir3 \) -prune -o -name '*.txt' -printAnd, to exclude directories with a specific name at any level, use the -name primary instead of -path.
find . -type d -name node_modules -prune -o -name '*.json' -print 5 I find the following easier to reason about than other proposed solutions:
find build -not \( -path build/external -prune \) -name \*.js
# you can also exclude multiple paths
find build -not \( -path build/external -prune \) -not \( -path build/blog -prune \) -name \*.jsImportant Note: the paths you type after -path must exactly match what find would print without the exclusion. If this sentence confuses you just make sure to use full paths through out the whole command like this: find /full/path/ -not \( -path /full/path/exclude/this -prune \) .... See note [1] if you'd like a better understanding.
Inside \( and \) is an expression that will match exactly build/external (see important note above), and will, on success, avoid traversing anything below. This is then grouped as a single expression with the escaped parenthesis, and prefixed with -not which will make find skip anything that was matched by that expression.
One might ask if adding -not will not make all other files hidden by -prune reappear, and the answer is no. The way -prune works is that anything that, once it is reached, the files below that directory are permanently ignored.
This comes from an actual use case, where I needed to call yui-compressor on some files generated by wintersmith, but leave out other files that need to be sent as-is.
Note [1]: If you want to exclude /tmp/foo/bar and you run find like this "find /tmp \(..." then you must specify -path /tmp/foo/bar. If on the other hand you run find like this cd /tmp; find . \(... then you must specify -path ./foo/bar.
There is clearly some confusion here as to what the preferred syntax for skipping a directory should be.
GNU Opinion
To ignore a directory and the files under it, use -pruneReasoning
-prune stops find from descending into a directory. Just specifying -not -path will still descend into the skipped directory, but -not -path will be false whenever find tests each file.
Issues with -prune
-prune does what it's intended to, but are still some things you have to take care of when using it.
findprints the pruned directory.- TRUE That's intended behavior, it just doesn't descend into it. To avoid printing the directory altogether, use a syntax that logically omits it.
-pruneonly works with-printand no other actions.- NOT TRUE.
-pruneworks with any action except-delete. Why doesn't it work with delete? For-deleteto work, find needs to traverse the directory in DFS order, since-deletewill first delete the leaves, then the parents of the leaves, etc... But for specifying-pruneto make sense,findneeds to hit a directory and stop descending it, which clearly makes no sense with-depthor-deleteon.
- NOT TRUE.
Performance
I set up a simple test of the three top upvoted answers on this question (replaced -print with -exec bash -c 'echo $0' {} \; to show another action example). Results are below

Both f10bit's syntax and Daniel C. Sobral's syntax took 10-25ms to run on average. GetFree's syntax, which doesn't use -prune, took 865ms. So, yes this is a rather extreme example, but if you care about run time and are doing anything remotely intensive you should use -prune.
Note Daniel C. Sobral's syntax performed the better of the two -prune syntaxes; but, I strongly suspect this is the result of some caching as switching the order in which the two ran resulted in the opposite result, while the non-prune version was always slowest.

cleanup 5 This is the only one that worked for me.
find / -name MyFile ! -path '*/Directory/*'Searching for "MyFile" excluding "Directory". Give emphasis to the stars * .
7One option would be to exclude all results that contain the directory name with grep. For example:
find . -name '*.js' | grep -v excludeddir 17 I prefer the -not notation ... it's more readable:
find . -name '*.js' -and -not -path directory 8 Tested in Linux Ubuntu 18.04 and 20.04.
Notice that the ./ (or */, see below) before and the /* (or *, but see the caveat below) after the folder name to exclude are required in order to exclude dir_to_exclude, and anything within it!
Also, for speed, and to not traverse excluded directories, notice the really important escaped grouping parenthesis and the -prune option. Ex: find -not \( -path "*/dir_to_exclude/*" -prune \).
To see examples of these escaped grouping parenthesis in the manual pages, run man find, and then press / to search. Search for the pattern \(, for instance, using the regular expression pattern \\\(. Press Enter to begin searching the man pages. Press N for "next match" while searching.
Summary
These work:
# [my favorite #1] exclude contents of `dir_to_exclude` at the search root
find -not -path "./dir_to_exclude/*"
# exclude all files & folders beginning with the name `dir_to_exclude` at the
# search root
find -not -path "./dir_to_exclude*"
# [my favorite #2] exclude contents of `dir_to_exclude` at any level within your
# search path
find -not -path "*/dir_to_exclude/*"
# exclude all files & folders beginning with the name `dir_to_exclude` at any
# level within your search path
find -not -path "*/dir_to_exclude*"
# To exclude multiple matching patterns, use `-not -path "*/matching pattern/*"`
# multiple times, like this
find -not -path "*/dir_to_exclude1/*" -not -path "*/dir_to_exclude2/*"[USE THESE] These work too, and are BETTER because they cause find to NOT unnecessarily traverse down excluded paths!:
(This makes a huge difference in speed (is 2x~100x faster)! See here and here. You can also search the man find pages locally for the strings \( and \) with the escaped search strings \\\( and \\\), respectively).
find -not \( -path "./dir_to_exclude" -prune \) # works here but not above
find -not \( -path "./dir_to_exclude*" -prune \)
find -not \( -path "./dir_to_exclude/*" -prune \)
find -not \( -path "*/dir_to_exclude" -prune \) # works here but not above
find -not \( -path "*/dir_to_exclude*" -prune \)
find -not \( -path "*/dir_to_exclude/*" -prune \)
# To exclude multiple matching patterns at once, use the `-not \( ... \)`
# pattern multiple times, like this
find -not \( -path "*/dir_to_exclude1/*" -prune \) \ -not \( -path "*/dir_to_exclude2/*" -prune \)...but these do NOT work:
# These do NOT work!
find -not -path "dir_to_exclude"
find -not -path "dir_to_exclude/*"
find -not -path "./dir_to_exclude"
find -not -path "./dir_to_exclude/"The key is that generally, to make it work, you must begin each matching pattern with either ./ or */, and end each matching pattern with either /* or *, depending on what you're trying to achieve. I say "generally", because there are two noted exceptions in the -not \( ... \)-style section above. You can identify these two exceptions by the comments to the right of them which say: # works here but not above.
Further Explanation:
- [BEST, depending on what you want] This WORKS! Exclude all files and folders inside
dir_to_excludeat the root of where you are searching.Note that this excludes all subfiles and subfolders insidedir_to_exclude, but it does NOT exclude thedir_to_excludedir itself.find -not \( -path "./dir_to_exclude/*" -prune \) - Also exclude the
dir_to_excludedir itself (and any file or folder with a name which begins with these characters).Caveat: this also excludesdir_to_exclude1,dir_to_exclude2,dir_to_exclude_anyTextHere, etc. It excludes ANY file or folder which merely begins with the textdir_to_excludeand is in the root directory of where you're searching.find -not \( -path "./dir_to_exclude*" -prune \) - [BEST, depending on what you want] to recursively exclude a dir by this name at any level in your search path. Simply add a wildcard
*to the front of the path too, rather than using the.to indicate the search root directory.find -not \( -path "*/dir_to_exclude/*" -prune \) - Recursively exclude any file or folder with a name which begins with the characters
dir_to_excludeat any level in your search path. (See also the caveat above).find -not \( -path "*/dir_to_exclude*" -prune \)
Summary:
In ./, the . at the beginning means "start in the current directory" (or in */, the * is a wildcard to pick up any characters up to this point), and in /* at the end, the * is a wildcard to pick up any characters in the path string after the / character. That means the following:
"./dir_to_exclude/*"matches all subfiles and subfolders withindir_to_excludein the root search directory (./), but does NOT match the directory itself."./dir_to_exclude*"matches all files and folders within the root search directory (./), includingdir_to_exclude, as well as all contents within it, but also with the caveat it will match any file or folder name beginning with the charactersdir_to_exclude."*/dir_to_exclude/*"matches all subfiles and subfolders withindir_to_excludein any directory at any level in your search path (*/), but does NOT match the directory itself."*/dir_to_exclude*"matches all files and folders at any level (*/) within your search path with a name which begins withdir_to_exclude.
Going further
From there, I like to pipe to grep to search for certain matching patterns in the paths of interest. Ex: search for any path that is NOT inside the dir_to_exclude directory, and which has desired_file_name.txt in it:
# Case-sensitive; notice I use `\.` instead of `.` when grepping, in order to
# search for the literal period (`.`) instead of the regular expression
# wildcard char, which is also a period (`.`).
find -not \( -path "./dir_to_exclude/*" -prune \) \ | grep "desired_file_name\.txt"
# Case-INsensitive (use `-i` with your `grep` search)
find -not \( -path "./dir_to_exclude/*" -prune \) \ | grep -i "desired_file_name\.txt"
# To make `dir_to_exclude` also case INsensitive, use the `find` `-ipath` option
# instead of `-path`:
find -not -ipath \( -path "./dir_to_exclude/*" -prune \) \ | grep -i "desired_file_name\.txt"To exclude multiple matching patterns, simply use -not \( -path "*/matching pattern/*" -prune \) multiple times. Ex:
# Exclude all ".git" and "..git" dirs at any level in your search path
find -not \( -path "*/.git/*" -prune \) -not \( -path "*/..git/*" -prune \)I use the above example as part of my sublf alias here (update: that alias is being expanded and moved into a sublf.sh script in this folder here instead). This alias allows me to use the fzf fuzzy finder to quickly search for and open multiple files in Sublime Text. See the links above for the latest version of it.
alias sublf='FILES_SELECTED="$(find -not \( -path "*/.git/*" -prune \) \
-not \( -path "*/..git/*" -prune \) \
| fzf -m)" \
&& echo "Opening these files in Sublime Text:" \
&& echo "$FILES_SELECTED" \
&& subl $(echo "$FILES_SELECTED")'References:

5Use the -prune option. So, something like:
find . -type d -name proc -prune -o -name '*.js'The '-type d -name proc -prune' only look for directories named proc to exclude.
The '-o' is an 'OR' operator.
-prune definitely works and is the best answer because it prevents descending into the dir that you want to exclude. -not -path which still searches the excluded dir, it just doesn't print the result, which could be an issue if the excluded dir is mounted network volume or you don't permissions.
The tricky part is that find is very particular about the order of the arguments, so if you don't get them just right, your command may not work. The order of arguments is generally as such:
find {path} {options} {action}{path}: Put all the path related arguments first, like . -path './dir1' -prune -o
{options}: I have the most success when putting -name, -iname, etc as the last option in this group. E.g. -type f -iname '*.js'
{action}: You'll want to add -print when using -prune
Here's a working example:
# setup test
mkdir dir1 dir2 dir3
touch dir1/file.txt; touch dir1/file.js
touch dir2/file.txt; touch dir2/file.js
touch dir3/file.txt; touch dir3/file.js
# search for *.js, exclude dir1
find . -path './dir1' -prune -o -type f -iname '*.js' -print
# search for *.js, exclude dir1 and dir2
find . \( -path './dir1' -o -path './dir2' \) -prune -o -type f -iname '*.js' -print This is the format I used to exclude some paths:
$ find ./ -type f -name "pattern" ! -path "excluded path" ! -path "excluded path"I used this to find all files not in ".*" paths:
$ find ./ -type f -name "*" ! -path "./.*" ! -path "./*/.*" 1 There are plenty of good answers, it just took me some time to understand what each element of the command was for and the logic behind it.
find . -path ./misc -prune -o -name '*.txt' -printfind will start finding files and directories in the current directory, hence the find ..
The -o option stands for a logical OR and separates the two parts of the command :
[ -path ./misc -prune ] OR [ -name '*.txt' -print ]Any directory or file that is not the ./misc directory will not pass the first test -path ./misc. But they will be tested against the second expression. If their name corresponds to the pattern *.txt they get printed, because of the -print option.
When find reaches the ./misc directory, this directory only satisfies the first expression. So the -prune option will be applied to it. It tells the find command to not explore that directory. So any file or directory in ./misc will not even be explored by find, will not be tested against the second part of the expression and will not be printed.
The -path -prune approach also works with wildcards in the path. Here is a find statement that will find the directories for a git server serving multiple git repositiories leaving out the git internal directories:
find . -type d \ -not \( -path */objects -prune \) \ -not \( -path */branches -prune \) \ -not \( -path */refs -prune \) \ -not \( -path */logs -prune \) \ -not \( -path */.git -prune \) \ -not \( -path */info -prune \) \ -not \( -path */hooks -prune \) If anyone's researching on how to ignore multiple paths at once. You can use bash arrays (works perfectly on GNU bash, version 4.4.20(1)-release)
#!/usr/bin/env bash
# This script helps ignore unnecessary dir paths while using the find command
EXCLUDE_DIRS=( "! -path /*.git/*" "! -path /*go/*" "! -path /*.bundle/*" "! -path /*.cache/*" "! -path /*.local/*" "! -path /*.themes/*" "! -path /*.config/*" "! -path /*.codeintel/*" "! -path /*python2.7/*" "! -path /*python3.6/*" "! -path /*__pycache__/*"
)
find $HOME -type f ${EXCLUDE_DIRS[@]}
# if you like fzf
find $HOME -type f ${EXCLUDE_DIRS[@]} | fzf --height 40% --reverseAlso for some reason, you won't be able to ignore /bin/ directory paths.
3To exclude multiple directories:
find . -name '*.js' -not \( -path "./dir1" -o -path "./dir2/*" \)To add directories, add -o -path "./dirname/*":
find . -name '*.js' -not \( -path "./dir1" -o -path "./dir2/*" -o -path "./dir3/*"\)But maybe you should use a regular expression, if there are many directories to exclude.
a good trick for avoiding printing the pruned directories is to use -print (works for -exec as well) after the right side of the -or after -prune. For example, ...
find . -path "*/.*" -prune -or -iname "*.j2"will print the path of all files beneath the current directory with the `.j2" extension, skipping all hidden directories. Neat. But it will also print the print the full path of each directory one is skipping, as noted above. However, the following does not, ...
find . -path "*/.*" -prune -or -iname "*.j2" -printbecause logically there's a hidden -and after the -iname operator and before the -print. This binds it to the right part of the -or clause due to boolean order of operations and associativity. But the docs say there's a hidden -print if it (or any of its cousins ... -print0, etc) is not specified. So why isn't the left part of the -or printing? Apparently (and I didn't understand this from my first reading the man page), that is true if there there is no -print -or -exec ANYWHERE, in which case, -print is logically sprinkled around such that everything gets printed. If even ONE print-style operation is expressed in any clause, all those hidden logical ones go away and you get only what you specify. Now frankly, I might have preferred it the other way around, but then a find with only descriptive operators would apparently do nothing, so I guess it makes sense as it is. As mentioned above, this all works with -exec as well, so the following gives a full ls -la listing for each file with the desired extension, but not listing the first level of each hidden directory, ...
find . -path "*/.*" -prune -or -iname "*.j2" -exec ls -la -- {} +For me (and others on this thread), find syntax gets pretty baroque pretty quickly, so I always throw in parens to make SURE I know what binds to what, so I usually create a macro for type-ability and form all such statements as ...
find . \( \( ... description of stuff to avoid ... \) -prune \) -or \
\( ... description of stuff I want to find ... [ -exec or -print] \)It's hard to go wrong by setting up the world into two parts this way. I hope this helps, though it seems unlikely for anyone to read down to the 30+th answer and vote it up, but one can hope. :-)
For a working solution (tested on Ubuntu 12.04 (Precise Pangolin))...
find ! -path "dir1" -iname "*.mp3"will search for MP3 files in the current folder and subfolders except in dir1 subfolder.
Use:
find ! -path "dir1" ! -path "dir2" -iname "*.mp3"...to exclude dir1 AND dir2
1find . \( -path '.**/.git' -o -path '.**/.hg' \) -prune -o -name '*.js' -printThe example above finds all *.js files under the current directory, excluding folders .git and .hg, does not matter how deep these .git and .hg folders are.
Note: this also works:
find . \( -path '.*/.git' -o -path '.*/.hg' \) -prune -o -name '*.js' -printbut I prefer the ** notation for consistency with some other tools which would be off topic here.
find -name '*.js' -not -path './node_modules/*' -not -path './vendor/*'seems to work the same as
find -name '*.js' -not \( -path './node_modules/*' -o -path './vendor/*' \)and is easier to remember IMO.
You can also use regular expressions to include / exclude some files /dirs your search using something like this:
find . -regextype posix-egrep -regex ".*\.(js|vue|s?css|php|html|json)$" -and -not -regex ".*/(node_modules|vendor)/.*" This will only give you all js, vue, css, etc files but excluding all files in the node_modules and vendor folders.
None of previous answers is good on Ubuntu. Try this:
find . ! -path "*/test/*" -type f -name "*.js" ! -name "*-min-*" ! -name "*console*"I have found this here
2You can use the prune option to achieve this. As in for example:
find ./ -path ./beta/* -prune -o -iname example.com -printOr the inverse grep “grep -v” option:
find -iname example.com | grep -v betaYou can find detailed instructions and examples in Linux find command exclude directories from searching.
6find . -name '*.js' -\! -name 'glob-for-excluded-dir' -prune 2 TLDR: understand your root directories and tailor your search from there, using the -path <excluded_path> -prune -o option. Do not include a trailing / at the end of the excluded path.
Example:
find / -path /mnt -prune -o -name "*libname-server-2.a*" -print
To effectively use the find I believe that it is imperative to have a good understanding of your file system directory structure. On my home computer I have multi-TB hard drives, with about half of that content backed up using rsnapshot (i.e., rsync). Although backing up to to a physically independent (duplicate) drive, it is mounted under my system root (/) directory: /mnt/Backups/rsnapshot_backups/:
/mnt/Backups/
└── rsnapshot_backups/ ├── hourly.0/ ├── hourly.1/ ├── ... ├── daily.0/ ├── daily.1/ ├── ... ├── weekly.0/ ├── weekly.1/ ├── ... ├── monthly.0/ ├── monthly.1/ └── ...The /mnt/Backups/rsnapshot_backups/ directory currently occupies ~2.9 TB, with ~60M files and folders; simply traversing those contents takes time:
## As sudo (#), to avoid numerous "Permission denied" warnings:

Among the approached variously suggested in this thread (How to exclude a directory in find . command), I find that searches using the accepted answer are much faster -- with caveats.
Solution 1
Let's say I want to find the system file libname-server-2.a, but I do not want to search through my rsnapshot backups. To quickly find a system file, use the exclude path /mnt (i.e., use /mnt, not /mnt/, or /mnt/Backups, or ...):

find / -path /mnt -prune -o -name "*libname-server-2.a*" -printi.e.
... -path <excluded_path> -prune -o ...noting that whenever you add the trailing / to the excluded path, the find command then recursively enters (all those) /mnt/* directories -- which in my case, because of the /mnt/Backups/rsnapshot_backups/* subdirectories, additionally includes ~2.9 TB of files to search! By not appending a trailing / the search should complete almost immediately (within seconds).
"Solution 2" (... -not -path <exclude path> ...) likewise appears to recursively search through the excluded directories -- not returning excluded matches, but unnecessarily consuming that search time.
Searching within those rsnapshot backups:
To find a file in one of my hourly/daily/weekly/monthly rsnapshot backups):
$ START="$(date +"%s")" && find 2>/dev/null /mnt/Backups/rsnapshot_backups/daily.0 -name '*04t8ugijrlkj.jpg'; END="$(date +"%s")"; TIME="$((END - START))"; printf 'find command took %s sec\n' "$TIME"
/mnt/Backups/rsnapshot_backups/daily.0/snapshot_root/mnt/Vancouver/temp/04t8ugijrlkj.jpg
find command took 312 sec ## 5.2 minutes: despite apparent rsnapshot size ## (~4 GB), it is in fact searching through ~2.9 TB)Excluding a nested directory:
Here, I want to exclude a nested directory, e.g. /mnt/Vancouver/projects/ie/claws/data/* when searching from /mnt/Vancouver/projects/:
$ time find . -iname '*test_file*'
./ie/claws/data/test_file
./ie/claws/test_file
0:01.97
$ time find . -path '*/data' -prune -o -iname '*test_file*' -print
./ie/claws/test_file
0:00.07Aside: Adding -print at the end of the command suppresses the printout of the excluded directory:
$ find / -path /mnt -prune -o -name "*libname-server-2.a*"
/mnt
/usr/lib/libname-server-2.a
$ find / -path /mnt -prune -o -name "*libname-server-2.a*" -print
/usr/lib/libname-server-2.a 2 The following commands works:
find . -path ./.git -prune -o -printIf You have a problem with find, use the -D tree option to view the expression analysis information.
find -D tree . -path ./.git -prune -o -printOr the -D all, to see all the execution information.
find -D all . -path ./.git -prune -o -print This is suitable for me on a Mac:
find . -name *.php -or -path "./vendor" -prune -or -path "./app/cache" -pruneIt will exclude vendor and app/cache dir for search name which suffixed with php.
I was using find to provide a list of files for xgettext, and wanted to omit a specific directory and its contents. I tried many permutations of -path combined with -prune but was unable to fully exclude the directory which I wanted gone.
Although I was able to ignore the contents of the directory which I wanted ignored, find then returned the directory itself as one of the results, which caused xgettext to crash as a result (doesn't accept directories; only files).
My solution was to simply use grep -v to skip the directory that I didn't want in the results:
find /project/directory -iname '*.php' -or -iname '*.phtml' | grep -iv '/some/directory' | xargs xgettextWhether or not there is an argument for find that will work 100%, I cannot say for certain. Using grep was a quick and easy solution after some headache.
For those of you on older versions of UNIX who cannot use -path or -not
Tested on SunOS 5.10 bash 3.2 and SunOS 5.11 bash 4.4
find . -type f -name "*" -o -type d -name "*excluded_directory*" -prune -type f 1 how-to-use-prune-option-of-find-in-sh is an excellent answer by Laurence Gonsalves on how -prune works.
And here is the generic solution:
find /path/to/search \ -type d \ \( -path /path/to/search/exclude_me \ -o \ -name exclude_me_too_anywhere \ \) \ -prune \ -o \ -type f -name '*\.js' -printTo avoid typing /path/to/seach/ multiple times, wrap the find in a pushd .. popd pair.
pushd /path/to/search; \
find . \ -type d \ \( -path ./exclude_me \ -o \ -name exclude_me_too_anywhere \ \) \ -prune \ -o \ -type f -name '*\.js' -print; \ popd 1 I tried command above, but none of those using "-prune" works for me. Eventually I tried this out with command below:
find . \( -name "*" \) -prune -a ! -name "directory"
