MakePU() {
cat <<EOF

TwoTrees t                                                                                                                                            
t.ToCheckPUReweight($SAMPLE)                                                                                                                               
.q                                                                                                                                                    
EOF

Functions have their own parameters, $2 is something local to the function when you try and use it. If you wanted the function to have parameters, you could call it like functionname parameter1 parameter2 ...

Or you could use global variables instead.

Hi Corona,
Thanks for the useful comment. Bu as I understood, If I define the variable in the starting that would be global in scope
Code:
#!/bin/bash

#Global variable ??
SAMPLE=$1   

Func()
{
NAME=$2   #local ??
}

Kindly comment,

Thanks,

SAMPLE is global, $1 is not. When you call a function it gets its own $1 $2 ... variables.

Try this.

Code:
#!/bin/sh

function asdf() {
        echo "asdf's 1 is $1"
        echo "asdf's 2 is $2"
}

echo "code's 1 is $1"
echo "code's 2 is $2"
asdf
asdf a b

Code:
$ ./myscript

code's 1 is
code's 2 is 
asdf's 1 is
asdf's 2 is
asdf's 1 is a
asdf's 2 is b

$ ./myscript q w

code's 1 is q
code's 2 is 2
asdf's 1 is
asdf's 2 is
asdf's 1 is a
asdf's 2 is b
