Sort files with grep

bashgreppipesorting

I have a few hundreds of output files, of which some contain error messages. Lets say I want to automatically put all files containing the string "ERROR_1" in a "subfolder_1", and the rest in a second "subfolder_2". This should be possible by piping grep somehow. What would be a useful syntax?

Best Answer

for a in *;do grep -q ERROR_1 "$a" && mv "$a" subfolder_1 || mv "$a" subfolder_2;done

This should work.

you can also use:

to do the whole thing in one command.

Linux – Read a file and pipe to grep

Avoid that useless use of cat. You can of course solve this with xargs and the like. But that's over-complex compared to a simple while loop.

while read i 
do
    grep -r -- "$i" directory/
done < filename
