I know I should no this, but I don't and was wondering if someone could enlighten me. I have some scalars that represent filenames and look like this<br>
<br>
my $fl1=3321-1.pdf<br>
my $fl2=3321-2.pdf<br>
my $fl3=3432-1.pdf<br>
<br>
I can get everything before the "-" like this:<br>
$fl2=~s/\-.*//; # get the root of the filename<br>
<br>
but how can I do it without changing the contents of the original scalar? I'd like to put the result directly in a new scalar.<br>
<br>
$root_name= $f12=~s/\-.*//; # get the root of the filename<br>
<br>
Thanks.<br>
