תשתמש ב-perldoc.
perldoc -f function
זאת אומרת שאתה צריך להשתמש ב-perldoc -f chomp

REMOVE THIS LINE
chomp VARIABLE
chomp( LIST )
chomp This safer version of "chop" removes any trailing string that
corresponds to the current value of $/ (also known as
$INPUT_RECORD_SEPARATOR in the "English" module). It returns
the total number of characters removed from all its arguments.
It’s often used to remove the newline from the end of an input
record when you’re worried that the final record may be missing
its newline. When in paragraph mode ("$/ = """), it removes
all trailing newlines from the string. When in slurp mode ("$/
= undef") or fixed-length record mode ($/ is a reference to an
integer or the like, see perlvar) chomp() won’t remove any‐
thing. If VARIABLE is omitted, it chomps $_. Example:
while (<>) {
chomp; # avoid \n on last field
@array = split(/:/);
# ...
}
If VARIABLE is a hash, it chomps the hash’s values, but not its
keys.
REMOVE THIS LINE
אם לא הבנת, זה מסיר בדרך כלל את ה-newline מסוף השורה.
