passing parameters to functions in shell script


Hi guys, I know we can write fucntions in shell script and call them with the following syntax:

function-name ()
{
command1
command2
....
....
}

and to call it we just give the command:

fucntion-name.


Now, can we pass parameters to functions by name/value just as we do it in C language? If yes, then How do we do that?

Thanks

Hi,

Bash (ksh) isn't that strickt when it comes to functions. Unless specifically set, variables are also known inside functions. Using $1, $2 etc also works.

Code:
#!/bin/bash

function callMe()
{
  echo "\$1 : $1"
  echo "\$varOne : $varOne"
  echo "\$2 : $2"
  echo "\$varTwo : $varTwo"
}

varOne="some text"
varTwo="100"

callMe "$varOne" "$varTwo"
When the function is called without variables, $1, $2 cannot be used.

Hope this helps.
