Like (apparently) ichi, I missed this in the Subject: line when you first posted it. Perhaps there's a lesson there ... it pays to write a few more words than the bare minimum your message needs, to make it *easy* (not just *possible*) for people to understand your question. This is not IRC, after all ... we can tolerate the extra space for a few more words fairly easily.

$5 is the 5th memory of a regular expression. The second statement then
uses a regular expression to replace " " with "\ " to correct paths.

$5=Somefolder/some secondfolder
$path would get Somefolder/some\ secondfolder.

I want to condsense this into one statement.

Why? This is not nagging, but a real question. I ask because while it should be possible to combine these two statments into one (just search on "obfuscated Perl" to see both how easy this is and how unreadable the resulting code can be), doing so probably will not make the program run any faster, and it will almost surely make it harder to read (and, hence, maintain).

So it would help to know your purpose in wanting to combine these statements. If you are looking to save time or memory, I doubt that modifying the source will help, at least not as long as you need $5 to continue to hold the unedited version of thestring while $path contains the edited version. As it is, you've written it just the way I would.

I am probably off topic
here but I have seen others post about basic programming issues.

Not off topic at all; these sorts of questions come up regularly, as you've noted.
