Find specific folders then search specific files inside them for a word

Question

I am trying to combine find and grep in a way to find folder names that start with k0 and search a specific file "test.log" for a word ERROR.

Something like:

find . -type d -name "k0*" -print | xargs grep ERROR test.log

unfortunately this command doesnt work as intended.

Answer 1

try this, I am assuming you have multiple files named test.log in the folders whose names start with k0 here:

for file in $(find ./k0* -name 'test.log'); do 
   grep -w 'ERROR' $file

done

You can make this into a one-liner command like this:

for file in $(find ./k0* -name 'test.log'); do grep -w 'ERROR' $file; done

It's executable on terminal if you just post it.
