Shell script - archive tar script

hi all,

Code:

 #!/bin/bash

    echo "is this archive for an audio tar (press 1) or an audio directory (press 2)"
    read method

    case $method in
        1)
            echo "please specify full path to tar file"
            read -e tar

            base=$(basename "$tar")

            echo "please enter ID number ie ID1234"
            read id

            echo "please specify where you want the tar file to be stored"
            read -e dest

            if ! mv "$tar" "$id"_"$base" ; then
                echo "something went wrong with the mv command, please do manually"
                exit
            fi

            if ! rsync -avh "$id"_"$base" "$dest" ; then
                echo "something went wrong with the rsync command, please do manually"
                exit
            fi

            if ! rm -f "$id"_"$base" ; then
                echo "something went wrong with the rm -f command, please do manually"
                exit
            fi
                
            ;;

        2)
            echo "please specify full path to directory you want to be made into a tar"
            read -e dir

            cd $dir
            cd ..

            base=$(basename "$dir")

            echo "please enter ID number ie ID1234"
            read id

            echo "please specify where you want the tar file to be stored"
            read -e dest

            if ! tar -cf "$id"_"$base".tar "$base" ; then
                echo "something went wrong with the tar, please do manually"
                exit
            fi

            if ! rsync -avh "$id"_"$base".tar "$dest" ; then
                echo "something went wrong with the rsync, please do manually"
                exit
            fi

            if ! rm -f "$id"_"$base".tar ; then
                echo "something went wrong with the rm -f command, please do manually"
                exit
            fi

            if ! rm -rf "$dir" ; then
                echo "something went wrong with the rm -rf command, please do manually"
                exit
            fi

            ;;

        *)
            echo "invalid selection, please re-run the script"
            exit

            ;;

script

SCRIPT(1)						    BSD General Commands Manual 						 SCRIPT(1)

NAME

     script -- make typescript of terminal session

SYNOPSIS

     script [-akq] [-t time] [file [command ...]]

DESCRIPTION

     The script utility makes a typescript of everything printed on your terminal.  It is useful for students who need a hardcopy record of an
     interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1).

     If the argument file is given, script saves all dialogue in file.	If no file name is given, the typescript is saved in the file typescript.

     If the argument command is given, script will run the specified command with an optional argument vector instead of an interactive shell.

     The following options are available:

     -a      Append the output to file or typescript, retaining the prior contents.

     -k      Log keys sent to program as well as output.

     -q      Run in quiet mode, omit the start and stop status messages.

     -t time
	     Specify time interval between flushing script output file.  A value of 0 causes script to flush for every character I/O event.  The
	     default interval is 30 seconds.

     The script ends when the forked shell (or command) exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-D (if
     ignoreeof is not set) for the C-shell, csh(1)).

     Certain interactive commands, such as vi(1), create garbage in the typescript file.  The script utility works best with commands that do not
     manipulate the screen.  The results are meant to emulate a hardcopy terminal, not an addressable one.

ENVIRONMENT

     The following environment variable is utilized by script:

     SHELL  If the variable SHELL exists, the shell forked by script will be that shell.  If SHELL is not set, the Bourne shell is assumed.  (Most
	    shells set this variable automatically).

SEE ALSO

     csh(1) (for the history mechanism).

HISTORY

     The script command appeared in 3.0BSD.

BUGS

     The script utility places everything in the log file, including linefeeds and backspaces.	This is not what the naive user expects.

     It is not possible to specify a command without also naming the script file because of argument parsing compatibility issues.

     When running in -k mode, echo cancelling is far from ideal.  The slave terminal mode is checked for ECHO mode to check when to avoid manual
     echo logging.  This does not work when in a raw mode where the program being run is doing manual echo.
