LinuxQuestions.org - Backup script to tar

Hi, I was attempting to write my first 'real' script today and had an issue with it. The script is suposed to take a directory, go through all the files in it and place the files into several 1 Gig sized tar files. It seems to divide the files up ok, but when it gets to where it runs the tar ... tar gives me errors about not being able to find the files. When i echo the tar command the script creates and then just copy the command into the console, the tar runs without a problem. Thanks for your time.

Code:

#!/bin/bash



check=$1                # directory to check

backdir=$2              # directory for backupfiles

maxsize=1000000        # size in KB of one tar



tarlist=""              # will contain space delimited file names

comsize=0              # total (complete) size of all files

i=1                    # file count



for files in $check/*

do

        size_w=`du -s "$files"`

        cursize=${size_w%*$files*}      # find the size of the current file

        if [ `expr $comsize + $cursize` -ge $maxsize ]

        then

                tarlist="$tarlist $files"

                totar="$backdir/$i.tar $tarlist"

                cmd="tar -cf $totar"

                echo $cmd

                $cmd

                tarlist=""

                comsize=0

                i=`expr $i + 1`

        else

                comsize=`expr $comsize + $cursize`

                tarlist="$tarlist \"$files\""

                i=`expr $i + 1`

        fi

done



totar="$backdir/$i.tar $tarlist"

cmd="tar -cf $totar"

echo $cmd

$cmd
