I did not quote that you are deleting the parent directory bit intend to delete 'WORKSPACE' inside the parent directory. That said I am looking at your "workspace_setup.sh"...

Code:

if [ "$#" -ne "3" ]
then
        echo -e "${RED}USAGE : script.sh WORKSPACE DATASET_PATH UTT_PATH${NC}"
    exit 1
fi
 
 
if [[ $1 = "" ]]
    then
        echo -e "${RED}Missing Workspace name! -  Provide a name!${NC}"
    exit 1
fi
 
 
if [[ $2 = "" ]]
    then
        echo -e "${RED}Missing path to dataset - SPH files${NC}"
    exit 1
fi
 
 
if [[ $3 = "" ]]
    then
        echo -e "${RED}Missing path to Utt!${NC}"
    exit 1
fi

Firstly '$1' can NEVER be NULL if """$2""" and """$3""" exist. They just shift places so that '$2' becomes '$1' and so on.

Code:

cd ../../../

Ouch! Where does this go in the event of an error?
I tried it and it put me into my root directory, if you need the root drawer then why not call it as cd /
If you know what the absolute directory addresses are then why not use them?
Alternatively use the /tmp/your/directory/tree/ to test with thoroughly and change all sources to /full/path/to/your/directory/tree/
You create links to parents of parents too - ouch!
You are also calling Python scripts which I don't intend to check at this point.
Also '$1', '$2', '$3' are script arguments and if any one is wrong or not present do you not have a failsafe to prevent this scenario?
There are other bits and pieces that I, as an amateur, would not do too.

LEARN ABOUT FREEBSD

pwd

PWD(1)							    BSD General Commands Manual 						    PWD(1)

NAME

     pwd -- return working directory name

SYNOPSIS

     pwd [-L | -P]

DESCRIPTION

     The pwd utility writes the absolute pathname of the current working directory to the standard output.

     Some shells may provide a builtin pwd command which is similar or identical to this utility.  Consult the builtin(1) manual page.

     The options are as follows:

     -L      Display the logical current working directory.

     -P      Display the physical current working directory (all symbolic links resolved).

     If no options are specified, the -P option is assumed.

ENVIRONMENT

     Environment variables used by pwd:

     PWD  Logical current working directory.

EXIT STATUS

     The pwd utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     builtin(1), cd(1), csh(1), sh(1), getcwd(3)

STANDARDS

     The pwd utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

BUGS

     In csh(1) the command dirs is always faster because it is built into that shell.  However, it can give a different answer in the rare case
     that the current directory or a containing directory was moved after the shell descended into it.

     The -L option does not work unless the PWD environment variable is exported by the shell.
