divide a directory into multiple archive files with tar

[ddaas]

Hi,
I want to divide a directory into a no. of archives with tar.
For example I have a big directory 'mydir'. I want to make 5 archives mydir1.tar, mydir2.tar, ... mydir5.tar from my big directory ‘mydir’.
Eventually I would like to have a text file with the content of every archive (filename and date).

How can I do that? I didn’t find any tar option which could help me.

You can write a script to do that:

         #!/bin/sh
         # USAGE
          function usage(){
              cat << EOF
                   -h print this help and exit.
                   -n tar archive name
                   -d directory to tar
           EOF
           &#125;

        # Default directory 
         dir=
        # Default tar name
         tar=

         while &#91; $# -ne 0 &#93;; do
             case $1 in
                      -h&#41;
                           usage
                           exit
                           ;;
                     -n&#41;
                          shift
                          tar=$1
                          ;;
                     -d&#41;
                          shift
                          dir=$1
                          ;;
                     *&#41;
                         echo "Unknown option $1" >&2
                         exit 1;
                         ;;
               esac
         done
 
         # Create the tar file
          tar cf $tar.tar $dir
         # Create the text file
          ls -Rl $dir > $tar.txt

If you call your script 'myscript' then:

 myscript -n tarname -d directory

should create a tar archive of name 'tarname.tar' with a file 'tarname.txt' listing every files in 'directory' with their dates.
If you assign a value to the variable 'dir' for example you can call

myscript -n tarname

Hope that helps.

thanks,
I'll try your script.
