There are several reasonable answers, and I'm not
sure which one you're looking for:
1) tr/ //d # remove all *spaces*
2) s/\s+//g # remove all "whitespace"
And check:
$ perldoc -q 'blank space'
For how to trim leading/trailing whitespace.
And fyi, chomp() removes $\, the input record
separator, which is a newline by default, gets
changed fairly often.
