Renaming a folder en-mass

Posted on by

I was figuring out a way to rename a folder en-mass which took me a few seconds, instead of about an hour of clicking.

Linux automation is a win.

# mmv "Documentary - National Geometry series-*.avi" "#1.avi"

I had some old tv series but they were all prefixed with the same filename ‘Documentary – National Geometry series’ before their volume number and title. So I found the above command to strip that out for all 100 of them, in a single command. Basically #1 is where * is in the source command regular expression, so everything after the source expression and between the *.

It’s a really nice utility and preferred on BSD systems to perl rename imo

Using Freebsd unrar utility properly and extracting recursively

Posted on by

I noticed I had a lot of unrarred files and needed a way to completely unrar everything in a folder. I noticed a lot of the examples on the internets didnt work.

find Archive/ -name '*.part01.rar' -execdir unrar e {} \;

This basically hunts out all directories below Archive/ and extracts all archives starting with part01.rar, the problem with examples I found is they used regex for *.rar or unrar’s -r recursive feature which in my BSD system seemed not best way to do this.

I was pleased with the oneliner though. It might be useful for people with freenas systems.
