Fix this script pls - unrar to specified dir

Postby Ozman on Sat Jul 14, 2012 7:52 pm

The situation is this: I have a main directory that contains sub-directories. Each sub-directory contains a file that is split into .rar parts. The script below, when put into the main directory, will extract each file from each sub-directory and put the assembled file into that sub-directory. However, I want all assembled files to be extracted to one directory: either /home/abc/main or preferably /storage/temp

I cannot work out how to do that with the script below. I have tried the options, but I am obviously doing something wrong.

          unrarall -h
DESCRIPTON
unrarall is a utility to unrar and cleanup (delete) all rar files within a directory DIRECTORY. Sub-directories are automatically recursed and if a rar file exists in a sub-directory then the rar file is extracted into that subdirectory.

Use --clean if you want to cleanup. Otherwise no cleaning is done. It can also be used to delete rar files that have already been used for extraction with --force. Use with caution!

OPTIONS

-c, --clean      Clean after unrar. If the extraction fails then the directory will NOT be cleaned. Use --force to override this.
-d, --dir        Use directory DIRECTORY. If this argument is not supplied the current working directory is used.
-f, --force      Force clean even if unrar fails. Implies --clean. Use this if you've already used unrarall on the directory before
                 and now you want to remove the rar files. This should be pretty fast as unrar is set to not overwrite already extracted files.
--full-path      Extract full path inside rar files instead of just extracting the files in the rar file which is the default behaviour.
-h, --help       Displays this help message and exits.
-v, --verbose    Show extraction progress as unrarall executes. This is not done by default
--version        Give version information version.

VERSION: $UNRARALL_VERSION
