A script must be written to extract and return a string value from a file. This must be done only after a match is found in the file for the given pattern.
This text is the sub part of a big log file and also many instances of this with
"id":"some value" could occur.
I need to return that 'some value' portion every time and from a lot of files in that directory.
sed utility in Unix helps here, but I couldn't figure out ts exact usage. Would be glad if somebody could help.
