Is there a func or a onliner for removing blanks from both ends?
I'm using these:
$username =~ s/^\s+//;
$username =~ s/\s+$//;
There got to be one out there!
thanks,

We could combine those:
$username =~ s/^\s*(.*?)\s*$/$1/;
Hope that helps.

Doing it in two steps is the way to go. Don't try to make one regex out of
it.
I usually write it this
this looks convenience

I ran some benchmarks.
The two-liner outperformed the one-liners by a 10 to 1 ratio. Code and
results below.
Benchmark: timing 10 iterations of OneLine, OneLine2, TwoLines...
OneLine: 41 wallclock secs (39.30 usr + 0.00 sys = 39.30 CPU) @ 2544.79/s
