Re: How to match a ;

That matches strings where the only character on the line is a ';'. To match just the first character where you don't care what follows, omit the $.

The regex of the OP will evaluate true for all strings except a string consisting of a single `';'` character optionally followed by a newline because `$line !~ m{^;$}` uses the `!~` negating binding operator. Update: corrected per GrandFather's reply below.	[reply] [d/l] [select]

Argh! Quite right. It must be the heat here! Well, any string except one containing a single ';' optionally followed by a \n. Perl's payment curve coincides with its learning curve.	[reply]
