[SOLVED] Can I call a function of a shell script from another shell script?

Issue

I have 2 shell scripts.

The second shell script contains following functions second.sh

func1 
func2

The first.sh will call the second shell script with some parameters and will call func1 and func2 with some other parameters specific to that function.

Here is the example of what I am talking about

second.sh

val1=`echo $1`
val2=`echo $2`

function func1 {

fun=`echo $1`
book=`echo $2`

}

function func2 {

fun2=`echo $1`
book2=`echo $2`


}

first.sh

second.sh cricket football

func1 love horror
func2 ball mystery

How can I achieve it?

Solution

Refactor your second.sh script like this:

func1 {
   fun="$1"
   book="$2"
   printf "func=%s,book=%s\n" "$fun" "$book"
}

func2 {
   fun2="$1"
   book2="$2"
   printf "func2=%s,book2=%s\n" "$fun2" "$book2"
}

And then call these functions from script first.sh like this:

source ./second.sh
func1 love horror
func2 ball mystery

OUTPUT:

func=love,book=horror
func2=ball,book2=mystery
