I am trying to run grep against a list of a few hundred files:
$ head -n 3 <(cat files.txt) admin.php ajax/accept.php ajax/add_note.php
However, even though I am grepping for a string that I know is found in the files, the following does not search the files:
$ grep -i 'foo' <(cat files.txt) $ grep -i 'foo' admin.php The foo was found
I am familiar with the
-f flag which will read the patterns from a file. But how to read the input files?
I had considered the horrible workaround of copying the files to a temporary directory as
cp seems to support the
<(cat files.txt) format, and from there grepping the files. Shirley there is a better way.
