Get bash script code to toggle between two values. This code is best suited for situations where you want to toggle the state of a switch from on/off. It can work for Booleans too like true to false and vice versa.
Code Example –
#!/bin/bash
arr=(true false)
cycle() {
printf '%s ' "${arr[${i:=0}]}"
((i=i>=${#arr[@]}-1?0:++i))
}
cycle
cycle
cycle
cycle
# Output:
# true false true false
