Re: dir match, dir may or may not appear

In your regex [^/]+{0,1} does not make sense if I understand it correctly, basically you say
anything but a slash, at least one time, then you say at least 0 time at most 1... you gotta choose which you want, either it is

[^/]+ or
[^/]? (equivalent to {0,1})
For what you want to do I'd say:
m#\A/usr/([^/]+/)?bin#

Thanks, I meant "(slash followed by anything except slash) to occur 0 or 1 time" Basically 0 or 1 dir can appear inbetween /usr and bin/	[reply]

The "?" quantifier means to match 0 or 1 times as specified in the "Quantifiers" section of perlre. Therefore your pattern to match this could be simply `(/[^/]+)?` which is similar to QuillMeantTen's approach above.	[reply] [d/l]
