I have a bit of SA code where I strip leading and trailing whitespace -
foreach (@addrs) { s/^\s*([^\s]+)\s*$/\1/; }
Whenever I run this I get the warning "\1 better written as $1" which I
understand to be perl telling me that the right side of s/// should use
$digit, not \digit. I tried changing it to $1, but that didn't produce
the expected result. What would be the correct way to write this?
s/^\s+//; s/\s+$//;
Your regex doesn't match " foo bar " at all.
