I think it's something like this, $1 being the first arg.

Code:

if ( "$1" != "" ) set port="$1"

Where port is what you want to name the variable.
Then:

Code:

echo $port

I know how to save it like that.....what I am actualy looking for is to 'take input' from the user and save it in a 'var'. But Thanks

Something like this? (in bold is my input)

Code:

skalkoto@darkstar:~/src$ ./ask_name
What's your name? John
hello John
skalkoto@darkstar:~/src$cat ask_name
#!/bin/bash

echo -n "What's your name? "
read var1
echo "hello $var1"
skalkoto@darkstar:~/src$

The command you are looking for is read.
