Search for string and return file name

[Örjan Johansson]

Hi all!

I'm trying to figure out how to go through all files with a certain
extension in a directory, search for a string and return the names of the
files that contains the string. I have written scripts before that opens a
single file for reading and writing, but have no clue how to go through all
files in a folder, like a wildcard *.log kind of thing. Any pointers?

TIA,
Örjan

See 'perldoc -f glob' or check out the Find::File module.

Might it be File::Find instead of Find::File?

if you're using ...IX try
grep -l "text" *.log

using perl try glob
foreach $file (glob "*.log") {
open FH,$file;
while (<FH>) {
if (m/text/) {print $file; last; }
}
close FH;
}

It's not clear if you want to search directories recursively or not.
In the latter case I'd simply let the shell do wildcard expansion, a
la

perl findfiles.pl mydir/*.log

with findiles.pl along these lines:

#!/usr/bin/perl -ln

use strict;
use warnings;

print $ARGV and close ARGV
if /whattaiwant/;

__END__


If your shell doesn't do wildcard expansion you may want to do it
yourself inserting this line:

BEGIN {@ARGV=map glob, @ARGV}

If you want to search recursively then File::Find or one of the
modules that build upon it is your way.


HTH,

if you're using ...IX try
grep -l "text" *.log

What if you're using Linux?

perl -lne'/string/ and print $ARGV and close ARGV' *.log

Thanx all you guys. Just like I suspected, there are tons of ways to
achieve everything. I've got several ideas to work with now. Thanks
again everyone for your input!
