Remove Leading 0's

[NeedHelp]

I've been tasked with another "fix" which seems simple but isn't (to me). I need to remove all leading 0s of a string:

"00000002035"

needs to be

" 2035"

Is there some function I can use to do this already? The spacing needs to remain the same though.

you should be able to use regex

I found this:

Perl Reference

which lead me to making this:

$mystring =~ s/^0*//;
$mystring =  sprintf("%- 18s", $mystring);

And does what I need. Is this the best method though?

I don't know anything about perl so I cant tell you if thats the BEST way to do it. From my little understanding of regular expressions, it 'looks good.'

My theory is, if it works leave it alone

Yes, that is a good way to do what you want.

Thanks for the input. This method seems to be working fine for now.

some other ways:

$new = sprintf "%d" , "000023";
print $new;

$val = "00032";
$new = int $val; 
print $new;

I never thought of the int $val method. That would work fine I would think.
