How to unrar lots of rars.
January 29, 2012 9:35 AM   Subscribe

So, I have a whole folder of .rar files. I would like to de-archive all of them, but can't seem to find a way besides clicking them one at a time. I am running Ubuntu, and the only program I've tried so far is the default archive utility program. I haven't been able to find a solution by googling, but maybe my keywords are off. Help me save hours of repetitive clicking!

You can't just do an "unrar *.rar" type command?

Install the unrar package, then do it from the command line.

I should mention I'm very new to Ubuntu. Could you possible give me a play by play on the command line thing?

If you want to do everything under the current directory in a oner:

 find . -type f -iname '*.rar' -exec unrar x -ad {} \;

That will extract them all, preserving folder structure, and putting the contents of each in a folder with the same name as the parent rar file.

Once you install unrar, it might be slightly more complicated than "unrar *.rar". According the unrar man page, the program only takes on rar file at a time, so you'll have to unpack everything in a loop. Consider:

sudo apt-get install unrar-free
for rarfile in `ls *.rar`; do unrar x $rarfile; done

Note that ayerarcturus's solution won't work if any of the files have spaces in the names.

ayerarcturus: the ls isn't required there, btw, you can just do:

for rarfile in *.rar; do unrar x $rarfile; done

Rarzombie is java based and might work for you.

Also, because i forgot to preview: you _really" want to write it as:

for rarfile in *.rar; do unrar x "$rarfile"; done

with the quotation marks, or else you'll end up in teh sitaution where a file with spaces or other weird characters will break everything. Or, use the find version above, which takes care of that (which is what my unrar script i use here does)

shopt -s extglob
find !(day*) -mindepth 1 -name '*.rar' -execdir 'rar' '-o-' 'x' '{}' ';'

(the day* thing is to ignore the links created by another script which puts files in folders based on how long ago they were downloaded)

Thanks all! That script worked well and the rarzombie program looks promising for next time as well.
