Bash Shell Scripting

How to iterate through an array in a Bash Shell Script

Written by Ian Carnaghan · 19 sec read >
  • Create a new Bash Shell Script eg.
  • Open the Script with an Editor eg. GEdit
  • Add the array definition through which the script should iterate
    array=( one two three four five )
  • The expression ${array[@]} contains all values within the array
  • Now we create a for loop to iterate through the array
    for num in ${array[@]}
    echo $num
  • Once the Script executes, all values within the array be be echoed to the screen.

    To extend the Script additional statements can be added to the body of the for loop
