Hi I an FTP folder called Input where I get sent files which look something like this:

"Guide to Iceland _ Chen-ping Wang itinerary T-987654987.pdf"
"Guide to Iceland _ T-123654875 Chen-ping Wang itinerary.pdf"

Basicly the description of the file can be different but it always includes "T-" and some numbers.

I need to create a bash script that copies the file to the folder ../Output and renames the file so the "T-" and the numbers comes first, and then rest of the filename.
Example: "T-123654875 - Guide to Iceland _ Chen-ping Wang itinerary.pdf"

I intended to use Grep to get the name right.
Searching for (.+)(T-d+) and replacing it with $2 - $1

But I can't get it to work right.

grep alone and replace to me doesn't look like a usable combo. How do you feel about sed?

$ ls *pdf
Guide to Iceland _ Chen-ping Wang itinerary T-987654987.pdf
Guide to Iceland _ T-123654875 Chen-ping Wang itinerary.pdf

And then a little for loop in bash:

$ for i in *pdf; do mv "$i" "$( echo $i | sed -r 's/^(.*)(T-[0-9]9)(.+)$/2 - 13/' )"; done

This iterates over all PDFs in the current directory; stores their name in $i for every iteration, echos the content through sed (and uses its output as the target of the mv). sed breaks up the file-name in three parts and rearranges these. I recommend replacing mv with echo mv for testing :)

Which gives us:

$ ls *pdf
T-123654875 - Guide to Iceland _ Chen-ping Wang itinerary.pdf
T-987654987 - Guide to Iceland _ Chen-ping Wang itinerary .pdf
