Is this from an array or the filesystem? If it's the filesystem, and it's unix, try: `ls ???1107` [download] if it's the filesystem, and it's Windows, try: `dir ???1107.*` [download] if it's an array, try: `my @filtered_files = grep { /^...1107/ } @files;` [download]	[reply] [d/l] [select]

Sorry, my english isnt so good. well , let me try to explain it on a other way. Ive got a tool, which read files from a server. those files have specific filenames. The differences of the filenames are the date, which is in the name included. like file a) xyz11072002.xyz file b) zyx11072002.xyz file c) xyz01012002.xyz Now i just want to filter the files, which include the date of yesterday or a other special day( 11.07.2002). All these files are saved on a extern server. And i want to filter the files bevor i save it , for ex. in an array or an any list. I hope i could explain it.. thanks for ur help greetz IceZero Originally posted as a Categorized Answer.	[reply]
