How to find all sub directories containing a particular file and then grep another file in those sub-directories?

Question

I have a folder containing 100 sub-directories.

dir1 dir2 dir3 dir4...

Each sub-directory contains a file simv.log

Also, each directory either contains - FAILED.txt or PASSED.txt file.

I want to grep a pattern "ABCD" in the simv.log files where FAILED.txt is present.

I can find all directories containing FAILED.txt by using: find. -name "FAILED.txt" -print "%h\n" find. -name "FAILED.txt" -print "%h\n"

How can I further use this output to grep ABCD in simv.log file of those directories?

Answer 1

find . -name "FAILED.txt" -printf "%h/simv.log\0" | xargs -0 grep -F ABCD

should do the trick

Answer 2

find . -name "FAILED.txt"   -printf "%h/simv.log\n"  | while read line ; do  grep ABCD -nr $line ; done;
