Re: search =~ for /'s

in reply to search =~ for /'s

Everyone has advised you to use a regex so far. However, when you know the position in the string to check for, substr is often a better method, as it is clearer and potentially has a lower overhead.

$new .= '/' unless substr $new, -1 eq '/';

$new .= '/' unless substr $new, -1 eq '/'; can someone explain what -1 does

[little]

see perlman:perlfunc

# 1st argument given: string to process
# 2nd argument given: offset
# so here it means regardless of the true length the 
# last character in the string
substr ($new, -1);
