We can create variables that may contain strings or numerical values. These global variables can be accessed by all the functions inside a script.

A simple script called function_11.sh with functions is as follows:

#!/bin/bash
# We will define variable temp for sharing data with function
temp="/temp/filename"

remove_file()
{
  echo "removing file $temp..."
}
remove_file

Test the script as follows:

$ chmod +x function_11.sh
$ ./function_11.sh

Output:

removing file /temp/filename...
