Need Help??

If I were trying to get just the entries in my current working directory whose names consist entirely of digits, I'd do it like this:

my @digit_dirs = grep /^\d+$/, <*>;

print join( "\n", @digit_dirs, "" );

If the entries of interest were in fact all "yyyymmdd" digit strings, I'd replace the "+" in the grep regex with {8}.

Thank you very much good people. I totally understood the concept. You all are the best. By the way if I get a satisfactory answer to a thread that I have started is there a way of closing/locking it? Cos I receive lot of reminders from root saying that I'd have to reply ...etc. Im just a beginner gentlemen so please let me know if there are any rules that I should follow. thanks	[reply]

If you are on unix or similar shell, use: `ls\|grep -P "^.\d{8}."` [download] -P in grep is for using perl regex within shell grep.	[reply] [d/l]
