unrar script / Some help needed

Allright, I'm trying to make a nice alias for extracting DVD, XViD, etc, and this is what it looks like right now:

find -name "*.r[0-9][0-9]" -exec unrar x -vy {} /mnt/TV/temp \;

The problem is, because I am using [0-9], it will keep on trying to extract the same file over and over again, cause unrar and rar seems to extract the file wheather *.r*-file you choose.

If I'll do it like this "*.rar" , it works for directories where there's only 1 *.rar. I want it to work no matter if the dir's looks like this;

blabla-part001.rar
blabla-part002.rar
..

blabla.r00
blabla.r01
..

blabla.rar
blabla.r01
..

Anyone know what to do?

Re: unrar script / Some help needed

Is each multi-part archive in a different directory?

Re: unrar script / Some help needed

You should only issue unrar for one of the rar files, not all of them.

I've written a script which does exactly what I think you want. I give it a directory as argument, and it would locate the sfv file (if there is any), and the proper rar file to launch unrar on. I can't post it in it's entirety here, but here are some pointers. "$DIR" below is the directory I've fed the script with (DIR="$1").

To find the sfv file I do like this:

SFVFILE=$(find "$DIR" -maxdepth 1 -iname '*.sfv' -printf '%f\n')

if [ $(echo "$SFVFILE" | grep -c .) -gt 1 ] ; then
    die 1 "Found several .sfv files. \n$SFVFILE \nI'm confused." 
fi

die is a function that prints the error message and exits with the given exitcode.

To find the correct rar file to start with I do like this:

RARFILE=$(find "$DIR" -maxdepth 1 -iname '*.part*.rar' -printf '%f\n' | sort | head -1)

if [ "x$RARFILE" == "x" ] ; then
    RARFILE=$(find "$DIR" -maxdepth 1 -iname '*.rar' -printf '%f\n')

    if [ $(echo "$RARFILE" | grep -c .) -gt 1 ] ; then
        die 1 "Found several .rar files. \n$RARFILE \nI'm confused." 
    fi
fi

if [ "x$RARFILE" == "x" ] ; then
    RARFILE=$(find "$DIR" -maxdepth 1 -iname '*.r00' -printf '%f\n')

    if [ $(echo "$RARFILE" | grep -c .) -gt 1 ] ; then
        die 1 "Found several .r00 files. \n$RARFILE \nI'm confused." 
    fi
fi

if [ "x$RARFILE" == "x" ] ; then
    RARFILE=$(find "$DIR" -maxdepth 1 -iname '*.r01' -printf '%f\n')

    if [ $(echo "$RARFILE" | grep -c .) -gt 1 ] ; then
        die 1 "Found several .r01 files. \n$RARFILE \nI'm confused." 
    fi
fi


if [ "x$RARFILE" == "x" ] ; then
    die 1 "Found no files ending with .rar, .r00 or .r01." 
fi

To identify the archived file (iso/img/avi/whatever):

IMGFILE=$(unrar lb "$DIR/$RARFILE") 

if [ $(echo "$IMGFILE" | grep -c .) -gt 1 ] ; then
    die 1 "Found several image files in rar archive. \n$IMGFILE \nI'm confused." 
fi

For the sfv check and subsequent unrar:ing I do like this:

if [ "x$SFVFILE" == "x" ] || $SKIPSFV ; then
    unrar e "$DIR/$RARFILE" || exit $?
else
    cksfv -C "$DIR" -f "$DIR/$SFVFILE" && unrar e "$DIR/$RARFILE" || exit $?
fi

Since there usually is only one file in the archive it is safe to use "unrar e" instead of "unrar x". unrar e will put the resulting file in the current directory.
