Scripting Question:

[Laura Eaves]

I am not sure but I think I remember using $# as the special variable 
holding the number of arguments in the containing script.
You can also do a for loop and collect and count them explicitly, but there 
is certainly a variable that will do it, and I think it is $#.

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?
