How to iterate through an array in a Bash Shell Script

No Comments
  • Create a new Bash Shell Script eg. loopThroughArray.sh
  • 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
    ${array[@]}
  • Now we create a for loop to iterate through the array
     
    for num in ${array[@]}
     
    do
     
    echo $num
     
    done
     
    
  • 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
