If that date format is consistent, use substr! `$ perl -E ' > $filename = q{20130101Customer100.imp}; > say $filename; > substr $filename, 0, 8, q{}; > say $filename;' 20130101Customer100.imp Customer100.imp $` [download] Cheers, JohnGG	[reply] [d/l]

Thank you John, thanks a lot...!!! yes - my filename will have a constant format. So,I hope substr works.	[reply]

now I need to truncate 20130101 from the file name As someone else mentioned, I'm not sure the word "truncate" quite fits. Here's a solution that gives you a bit more flexibility: `\| hand waving here... my $fname = "20130101Customer100.imp"; # gotta go somewhere.. $fname =~ m@^(\d+)([A-Za-z0-9]+)\.imp$@; # Capture what we are looking + for... my $dateStamp=$1; my $basename=$2; \| do something with this.` [download] This will result in the scalar `$dateStamp` containing "20130101" and `$basename` containing "Customer100". The presumption I made (you didn't specify otherwise) was that your filenames all have the extension "imp" and as long as they do the regex I supplied you will work. I leave it as an exercise in intellect for you to modify the regex if there are other extensions involved. Peter L.

Hi Monks, Thank you all for spending some quality time to solve my issue. I see two/three sollutions will definitely solve my problem, also surprised to see you guys gave some extra analysis which was interesting. Sorry I din't mention that - my filename will have the same filename format everytime. Thanks again.......!!!!!	[reply]
