Question

I have a command which finds all the files containing a certain string on linux:

find . -type f | xargs grep 'string' -sl

What I want is to also print the time and date that the file was last modified.

Answer 1

You can do this:

grep -rl "string" *|xargs ls -l

If you want only the times:

grep -rl "string" *|xargs ls -l|awk '{print $NF, $6, $7 }'

will print something like:

file1 2012-03-25 12:44
file2 2012-03-26 00:30
