Need Help??

This snippet does the following:

Copies the contents of $fname to $bname
Binds the regular expression to $bname
Removes everything up to the final backslash ( \ ) from the string stored in $bname. Specifically, this expression (using the alternate delimiter '#') greedily matches any number of any characters (.*) followed by a backslash (which must be escaped, thus \\).

So the string 'C:\folder\file' would be transformed to 'file'.

All the details needed to parse the regular expression can be found in perlre and/or prelretut.

Thank you wise monk(s)! My confusion has blossomed into amusement. The original "programmer" was only good at "pasting". Original code: `$fname = $TMP_DIR . "\\" . $tnum . ".tmp"; ($bname = $fname) =~ s#.\\##s;` [download] New code: (terseness removed)* `$bname = $tnum . ".tmp"; $fname = $TMP_DIR . "\\" . $bname;` [download]	[reply] [d/l] [select]

If you are just modifying paths, you may consider using the File::Spec module. May very well be overkill for your app, though.	[reply]
