G'day Gtforce,

"Both typos corrected on the post (the original code that I have is ok), apologies."

It's fine to make corrections to your posts, but you also need to indicate what's changed at the point where the change occurred (e.g. you've said you made a correction here, several screenfuls away from the correction, but there's no indication of that in the OP itself). When I first read this thread, I couldn't initially understand why people were saying use 'qx' instead of 'qw': your OP had no apparent 'qw'. See "How do I change/delete my post?" for a more complete discussion.

Because it's directly related, and to save writing a separate reply, in "Re^2: search/grep perl/*nix" you wrote:

"It is qx and I did have the ending semicolon (daft of me to make these typos on the post), apologies."

The easiest way to avoid this, and what I do, is to just copy and paste your code directly into your post. This is a lot less work than actually typing your code and, because there's no typing involved, you won't make typos.
