Need a little help in making a script to help automate unraring

this is what i have to far it works but for some unknown reason the files aren't extracted to the same folder as the rar files but the parent folder

Code:

#!/bin/sh

dir=$1

find "$dir" -name "*part1.rar" -exec unrar -y -o- x {} "$dir" \;
find "$dir" -name "*part01.rar" -exec unrar -y -o- x {} "$dir" \;
find "$dir" -name "*part001.rar" -exec unrar -y -o- x {} "$dir" \;
find "$dir" -name "*.r00" -exec unrar -y -o- x {} "$dir" \;
find "$dir" -name "*.rar" -exec unrar -y -o- x {} "$dir" \;

fi

also a way to have all 5 rar types together in one line would be really cool

(note $1 / $dir = /temp/some.random.folder.name and the extract folder is for some reason /temp)

With the find command:

the option -exec causes the command to be executed in the starting directory, in this case the value in $dir.
the option -execdir causes the command to be executed in the subdirectory containing the file with the matching name. However, for security reasons, is you use -execdir find does not want . ( the current dir ) to be in your PATH.

AFAIK, unrar wants the directory into which you want it to extract the files, to already exist.
So if you just want the files extracted to the directory containing the rar file, you could pass . to unrar. You can "or" conditions together using the -o option. Also, AFAIK although it doesn't necessarily have to be, the "command" ( in this case x ) to unrar is supposed to be right after unrar itself. Examples:

unrar extracts files to the directory /home/me/wherever:

Code:

find /home/me/wherever \( -name '*part1.rar' -o -name  '*.rar' \) -exec unrar x -o- -y '{}' . \;

unrar extracts files to the directory containing the .rar file:

Code:

find /home/me/wherever \( -name '*part1.rar' -o -name  '*.rar' \) -execdir unrar x -o- -y '{}' . \;

unrar extracts files to the existing sub-directory named sub within the directory containing the .rar file:

Code:

find /home/me/wherever \( -name '*part1.rar' -o -name  '*.rar' \) -execdir unrar x -o- -y '{}' sub \;

unrar extracts files to the sub-directory named some_dir within the /tmp directory:

Code:

find /home/me/wherever \( -name '*part1.rar' -o -name  '*.rar' \) -execdir unrar x -o- -y '{}' /tmp/some_dir \;

HTH.

thank you for the reply it's working perfectly

would it be possible to also once the archive has been extracted (successfully?) to then delete the files?
