Scripting Question:

[Sean McMahon]

use the $# variable you could say if $# -lt 1 echo 'I don't know what to do with
that'
Really, you should look at using getopts in your sh scripts.  you did mean shell
scripts right?  If you meant shell scripts sh is of course the most portable.

Subject: Scripting Question:


Can someone tell me how to determine how many parameters are passed to a
script when the script is called?

For example a simple script called trythis:
#!/bin/bash

Echo -e $0

And when you call the script:
trythis 1 2 3 4 5

I get the output
trythis

What I want to see is that 5 parameters were passed to the script.

Any suggestions?
