Help on RegExp nedded

Kalin Evtimov — Fri, 03 Mar 2006 04:08:57 GMT

Hi!
I am stuck..
I need a regexp, which finds a file named 'something.log'
My regexp finds also something.log.1 and something.log.2 and so on..argh...

It says:
if ($file =~ /something.*.log/)....

How should I change it?

Thank you!

Hi Kalin,

Can you try,

if ($file =~ /something.*.log$/)....

Notice there is "$" after log character.

Kalin,
have you tried:
if ($file =~ /something*.log/)....

(removed first full stop)

Senthil Kumar .A Â´s version worked, I just added brackets:

$file =~ /something.*[log]$/

but it should work also without brackets.

Thank you!

the brackets are groups of chars to match to. now your regex will also match all files ending with the letters l, o or g. ex: ogl, gol, glo, gl, ol, lo, go, o, ...
not what you want i guess. it hasn't happened to you yet, because you don't have any other files with an extension made out of the letters l, o or g. but you can never be sure (.o files are common)
