“… add a file extension to a group of files that don’t currently have one …”

This is perhaps misleading. It adds the .txt extension to *every* file in the directory, including those that already have an extension. eg x.rtf becomes x.rtf.txt.

I wanted to add the one level parent folder name to all the files within the directory.

Any commands/ help….

Great tip. Unfortunately exactly 24 hours too late for me. I ran into this problem yesterday and figured it would have taken more time to find the solution than to just do it by hand.

You can also drag and drop a directory from the Finder into the terminal window to print out it’s path, rather than manually entering it.

its, not it’s

zsh, which is essentially a more modern, augmented form of ksh, makes this (and all batch renaming) much more fun with zmv:

zsh-% ls
test0 test1 test2 test3 test4

zsh-% mmv * *.txt
zsh-% ls
test0.txt test1.txt test2.txt test3.txt test4.txt

zsh-% which mmv
mmv: aliased to noglob zmv -W

Helpful tip I can definitely see when I would need to use this.

BTW not to be overly critical but I think Will is better at writing the command line tips….
