ksh script that will accept arguments

Shell Programming and Scripting

Hi,

I am not very skilled using ksh scripts.

How do I create a ksh script that will accept arguments and use them in the script ?

I need to make this:

Run this command with this argument:

./mykshprogram.ksh madsen

and sometimes I need to do this:
Run the ksh again with 2 arguments:

./mykshprogram.ksh madsen jensen

So I need something like this:

if argument 2 is empty
do
 /usr/tools/run.exe -i madsen
else
 /usr/tools/run2.exe -i madsen -y jensen

Thanks in advance

Maybe:

if [ $# -lt 2 ]
then
   /usr/tools/run.exe -i $1
else
   /usr/tools/run2.exe -i $1 -y $2
fi
3 
if [ -z $* ];then
/usr/tools/run.exe -i madsen
elif [[ -n $1 && -z $2 ]];then
 /usr/tools/run2.exe -i $1
elif [[ -n $1 && -n $2 ]];then
 /usr/tools/run2.exe -i $1 -y $2
fi

edit: i thought you said if all args were empty , thats why i added 1st if.

For more robust command line argument processing, read up on the "getopts" program for parsing command line options. Here is one example I found that addresses this:
KSH - Sample program - Scroll down a few examples to see the example that uses getopts.
