How do I get rid of comments via Perl?

## awk_tips.awk
# How many characters per line?
$ awk '{ print length($0) }'

# How many words per line?  Add -F for separator
awk '{ print NF }'

# How do I see a substring?  Example, 4 characters starting at position 2
$ awk '{ print substr($0, 2, 4) }'

# Alternative to the above, use cut:
