Remove Spaces with underscore

kaalraa

Hi,

I know.. this is basic question to ask over here... but still.

I need to replace the spaces given in a filename with underscore. May it be any number of spaces in between two words, it should be replaced by only and only one underscore.

e.g - the name given as - "testing for replace ment" should be taken as "testing_for_replace_ment".

At present i am using the following but it replaces each space with an underscore:

$fileName=~s/[\s|-|+]/_/g;

Please note that [...] denotes a class and '-' symbol indicates a range. Although syntactically correct, your range looks a bit strange.
(Vertical line will not work as "Or" here - apologize if I state the obvious....)

So, my guess is you want something like the following:
$fileName = ~s/[\s\-\+]+/_/g;
