I think you are confusing UNIX/Linux shell pattern matching with Perl. Perl uses Extended Regular Expressions for its pattern matching, it only uses shell patterns for filename expansions (globbing). Your if statement should be something like this: `if ($test =~ /^dump.*txt$/) { ... }` [download] Notice, lower case if with the condition in parentheses. Update: corrected RE	[reply] [d/l]

In addition to the response you already got, note that the angle operator, when given a glob pattern, returns a list of files matching the pattern `my @files=<dump*txt>` [download] Also have a look at File::DosGlob and perlre. -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l]

See the following sample code. it will match the file name starting with dump and followed by some text and ending with.txt `#!/usr/bin/perl use strict; use warnings; my @files = qw(dump123.txt abc dump124.txt 123 xyz 12dumpa.txt); foreach (@files) { if ( $_ =~ m/^dump.*txt$/) { print $_."\n"; } } <br>` [download] --sugumar--	[reply] [d/l]

Hi, Here find the piece of code im using.. pls tell me where im going wrong... i took all your advice and since glob din workout i did the last piece of code. here it is #!/usr/bin/perl $path = "path to the directory"; chomp($path); chdir($path); @lis = `ls`; foreach (@lis) { if ($_ =~ m/^dump*txt$/) #say the file i want is dump_234_129_15.txt { print $_."\n"; } } [download] here the @lis has all the different files in the directory... but the specific file is not fetched..

Hi All, I managed to find the mistake i was doing..U guys have been very very helpful.. i missed out the . `if ($_ =~ m/^dump.*txt$/)` in the if statement. So i guess the script was looking for a file starting with dump and ending with txt. but now its working fine.. Thanks a lot.. you guys rock.. will be back for more... :)	[reply] [d/l]
