Hi,
Thank you for all your help and time. I really appreciate it.
On our server, which runs "Red Hat Enterprise Linux AS release 3 (Taroon
Update 8)"
Lloyd (python at venix.com)'s solution works:
find -type f -name '*out*' | xargs grep -wli zip > zip.txt
Question: "-type f" limits to "regular file", does the so-called "regular
file" strictly mean "plain text files"?
Also, solution from Ben (w/ adding search pattern, which is "zip") and Bill
(w/ moving "zip" ahead of ".") works:
grep -lwir --include=\*out\* zip . > zip.txt
-------------------------------------------------------
Steven's solution (listed below) only partially works, for reasons I don't
know. By "partially", I mean his solution can only find SOME files matching
the search criteria.
find . -type f -name \*out\* | \
xargs file | \
awk '/ASCII/ { sub(/:/, ""); print $1}' | \
xargs grep -l zip > zip.txt
-----------------------------------------------
Kevin, in your solution (listed below), why are there 2 directory names are
used? Could you please explain a bit to me? Thank you.
find your-dirname1 your-dirname2 -name \*out\* \
-exec perl -e 'undef $/;
$filename=$ARGV[0];
$_=<>;
exit(!(-T $filename && /\bzip\b/))' \{\} \; -print \
>zip.txt
BTW, yes, I'm serious about the "plain text files" part.
And thank you for your favorite alias, I've not tested though.
----------------------------------------------
Bill, your another solution (listed below), based on Steve's, doesn't work
:-(
find . -name '*out*' -exec file '{}' '|' grep -q ASCII ';' -print0 \
| xargs -0 grep -wli zip > zip.txt
Again, thank you guys all!
Zhao
