How to match string end for a multiline string?

[Peng Yu]

Hi,

$ matches line end. When a string has multiple lines, how to much the
last line end?

Thanks,
Peng

No, it matches end of string, not end of line.

If used with //m, _then_ it matches end of line.

/$/

See it for yourself:

-------------------------------
#!/usr/bin/perl
use warnings;
use strict;

$_ = '
foo
bar
baz
';

s/$/END-OF-STRING/;

print;
