What would be the simplest way to remove leading and trailing blanks
from a user input?
To remove just blanks (but preserving possible trailing newline):
s/^ +//, s/ +$// for $input;
To remove all whitespace:
s/^\s+//, s/\s+$// for $input;
I like this idiom, because you can easily trim several variables at once:
s/^\s+//, s/\s+$// for $foo, $bar, $baz;
s/^\s+//, s/\s+$// for @array;
s/^\s+//, s/\s+$// for values %hash;
