Greekozz,
As I said in my explanation above, the shell will interpret metacharacters.
If you do not want it to happen before the data is sent to your script,
then:
1) Escape it.
2) 'set -f'
In this case, either one must be done in the unix prompt.
To escape it:
Code:
your_shell.sh 2 '*' 3
or
your_shell.sh 2 "*" 3

To 'set -f':
Code:
unix prompt>set -f

Or you could do this in bash.

Within your script, look for the keyword 'noglob' in the env variable SHELLOPTS. If it is present, then it means set -f was done. Else do a set -f and then exec yourself again.

Something like
Code:
#! /bin/sh

opts=${SHELLOPTS}
if [[ $opts = *noglob* ]] ; then
  # run the script
else
  set -f
  exec $0 $*
fi;

Not tested tho'.
