ksh functions
Hi All,

just wanted to ask if functions created in a Korn shell script can be passed parameters and if so what is the syntax for creating a function with parameters?

thanks

Yes - example
Code:
myfunction()
{
    echo "$1 $2"
}

myfunction "This is parameter 1"  " Another parameter"
myfunction  32 64

You call the function with a list of parms, inside the function the parms are identified by $n where n is the number of the parameter.

thanks for the speedy response Smilie

could it also return a single value if i used a return statement i.e. return $x ?
I have tried it but doesn't seem to work.

Return statement is used to return an exit value from a shell function to the calling script.

To return string use echo statement.
Code:
myfunction()
{
    echo "$1"
}

str=$( myfunction "This is parameter 1"  " Another parameter")
echo $str
