[LUNI] shell scripting question...

[Constantin Gavrilescu]

make a test.sh file with this content:

#!/bin/bash
echo $0

do a chmod +x test.sh
Run it with ./test.sh
It outputs "./test.sh".

Now make a symbolic link to that file:
ln -s test.sh script.sh

Run the symbolic link. It will output "./script.sh".

Now you know that a which symlink is calling the program. You can go from
there to:

 ln -s test.sh "test param1 param2 param3.sh"

You created a symbolic link with params. Change test.sh to:

#!/bin/bash
PROGRAM_NAME=$0
echo first parameter is : `echo ${PROGRAM_NAME} | awk '{print $2}'`
echo second parameter is : `echo ${PROGRAM_NAME} | awk '{print $3}'`

Now you are passing parameters through symbolic links.
