zcat pipe to grep

Question

ls -ltr|grep 'Mar  4'| awk '{print $9 }'|zcat -fq |grep  12345

I want to find all files modified on a certain date and then zcat them and search the fiels for a number string.

the above doesn't work because it searches the file name for the string not the file itself.

Any help?

Use xargs to run the grep on the filenames output by awk:

ls -ltr | grep 'Mar 4' | awk '{print 9}' | xargs zcat -fq | grep 12345

Or, I guess, run the rest of the pipe from awk itself.
