Question on Chomp

[Matt Taylor]

I have this piece of code:

$/ = ' ';
$test = "abc ";
chomp $test;
print $test;

which prints spaces at the end of the line. Shouldn't chomp strip the spaces
off the end of my scalar $test?

try:

$/ = ' ';
$test = "abc ";
print "$test<\n";
chomp $test;
print "$test<\n";

D:\Snippets>chomp.pl
abc <
abc <

stripping can be done with:

$test =~ s/\s*$//;

ie. remove zero or more (*) white space (\s) form the end ($).

Ah. Reading through perlfunc it sounded like chomp ate every trailing
string. I've never really questioned how to use it since I've used it
exclusively to chomp the newlines off of file input.

Thanks for the help.
