These are much easier to do with variable substitution. It sounds hard to get started, but it's easier when you get the hang of it.

Is SCRIPT_NAME a value you will read as input or do you want it to be the name of the script you are already running? The current running script will be known as $0, parm 1 is $1, parm 2 is $2 etc.

If you are using this, then you can slice the values up however you like, such as:-

Code:

SCRIPT_NAME=$0
echo $SCRIPT_NAME

SCRIPT_NAME="${0##*/}"               # Trim off everything up to and including the last /, i.e. the path.
echo $SCRIPT_NAME

SCRIPT_NAME="${SCRIPT_NAME%.sh}"     # Trim off a trailing .sh from what you've already got
echo $SCRIPT_NAME

PARM1=$1
echo $PARM1

You might be wanting to read from an input file as you seem to suggest with your done <"ListFile.txt" so you could also do this:-

Code:

while read scr par1 par2
do
   trimmed="${scr%.sh}"
   echo "I'm running $trimmed with parm1=$par1 and parm2=$par2"
   echo "My completion flag will be $trimmed.$par1.$par2.finished"
done < listfile.txt

Does that help?

Be aware that if you have three parameters, then this while read will put the 2nd & 3rd parameter into $par2

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
