If you are using Bash, then I suggest that you search for a Bash Tutorial. I always go to the Mother Lode http://tldp.org/. See Footnotes.

Here you can find Bash Programming - Introduction and Advanced Bash-Scripting Guide

Using a couple of things gleaned from the HOWTO, here is a bash shell that runs on my Linux systems:

Code:

#   showargs.sh: Bash script to show arguments
count=0
for i in $*
do
    count=$((count + 1))
    echo "Argument number $count: $1"
    shift
done
echo
echo "Number of arguments = $count"

A couple of runs, from a Bash shell:

Code:

$ ./showargs.sh

Number of arguments = 0
$

Code:

$ ./showargs.sh This is a test
Argument number 1: This
Argument number 2: is
Argument number 3: a
Argument number 4: test

Number of arguments = 4
$

Regards,

Dave

Footnotes:

1. If you are using some other shell (tcsh, ksh, sh (the original UNIX Bourne shell), or whatever), then you can search for tutorials on that one. When asking a question that is not about standard C or C++, you should always give full information (what Operating System, for example).

2. If you read through the HOWTO, you can even find an example of a File re-namer script

3. This doesn't really belong in a C programming forum since it has nothing to do with the C language. If you are using Linux, maybe it should be posted on the "Computer Software Forum - Linux" part of gidforums. If something else, then, maybe on the "Miscellaneous Programming" part. (I assume that you are not using the Microsoft cmd.exe shell, but if you are, then you can post on the "Computer Software Forum - Windows" part.)
