Re: help on reg ex

I'm assuming your second example of $a is a typo and should have read $a = '/export/home/test'. If you want to chop out great specifically, you can do:

$a =~ s/\/great$//;
[download]

If you want to generically remove the last element, and save it to $bar, you can do:

$a =~ s/(\/.*)$//;
$bar = $1;
[download]

I hope this helps.

Your example: `$a =~ s/(\/.)$//; $bar = $1;` [download] would put in $bar everything starting from the first slash. You should instead do: `$a =~ s#(/[^/])$##; $bar = $1;` [download] -- zigdon	[reply] [d/l] [select]

Oops, you're right. My bad -- I don't know what I was thinking :) You provide a good example to the user of a case where it's a good idea to use a nonstandard regex delimiter, BTW. Cool.	[reply]
