Adding an extension to a group of filenames
Hi -
I'm stuck. I have a group of text files created using the split command. My files have the names "projectaa", "projectab", "projectac", etc. What I want to do is add the extension ".txt" to each file. I think I've got part of a sed command together, but I'm stuck on my regex - I keep getting an error "Illegal variable name".

Here's the regex I created:

ls -d * | sed "s/^project[a-z][a-z]$/mv '&' \.txt/" | sh -v

Can anybody help me fix this? Or, offer an alternative way of renaming the files? I don't want to use the mv command by itself because each time I use split on a new text file, I won't know how many new files will be created.

Thanks!
