Where are your capturing parentheses?
my ($path,$filename) = $path_and_filename =~ m#^(.*?)/([^\]+)$#;
# using # instead of / for clarity
# ^ anchor at beginning of string
# ? non-greedy match modifier, which, on reflection,
# might actually make this less efficient
# / literal slash
# [^/] character class matching anything but slash
# $ end-of-string anchor
there's a module that deals with paths and file names in a non-os-specific
way
Those documents may be dull, but they made PERFECT SENSE TO WHOEVER
WROTE THEM and if you can figure out a better way to say something that is
in one of them you can get your name in the authors file.
I reccommend mark jason dominus's regular expression discussions which are
somewhere on plover.com for a good discussion of how regexen work.
Have a nice day!
