With a batch-file:

:: Q:\Test\2018\12\26\SU_1387726.cmd
@Echo off
For /F "tokens=2,3 delims={,}" %%A IN ( ' findstr "{" rule.txt'
) DO ECHO:%%A =^> %%B

sample output:

> Q:\Test\2018\12\26\SU_1387726.cmd
100 => 1011
india => o891
1100 => 101

If you are trying to capture the data inside the curly braces then you may use the following powershell command.

Get-ChildItem rule.txt | Select-String -Pattern '(?<={).*?(?=})' | % { $_.Matches } | % { $_.Value }

Output

100,1011
india,o891
1100,101
