Hi all,
It might seem like a very trivial question but I am new to shell scripting so excuse for that.

I have an existing script in CSH. I need to create a function in the script which takes some parameters and returns a result. Can someone please let me know the syntax for function declaration and how to call the function passing parameters.

Also if someone has a good tutorial with examples on CSH please send me the link.

Thanks in advance.

Regards,
Tipsy

I had a similar problem with declaring the functions in csh.
A simple script as below worked well in sh shell
#! /bin/sh

display()
{
echo "Inside display()"
}

echo "calling display()"
display

however when the shell interpreter was changed to "csh" it failed with following error :-
"Badly placed ()'s"

It looks like csh shell scripting doesn't support functions.

I have been searching over the net now for quite sometime for the function syntax in csh but never found one.

Please let me know if anyone finds the solution for the same.

Best Regards,
brendon

#!/usr/bin/csh

ThisIsAFunction()
{
echo "$1 $2"
}

#Main

VAR1=Hi
VAR2=there
ThisIsAfunction $VAR1 $VAR2

-------------------

Running this script would result in:

Hi there

on your screen.

Passing parameters to a functions is like passing arguments to a script. They are stored in $1, $2, $3 etc
Running this script would result in the following

Seems to be an issue with your CSH.

You can trying to replace the double quotes (") by single quotes (') in the echo commands.
This would work fine as long as you don't want to echo values of variables to the screen.

It doesn't support functions,
you can use aliases.
