Until loops are very similar to while loops except they run as long as the exit status of the condition is unsuccessful.
until [ condition exits successfully ] do # Commands here done
Here is a quick example that runs the until loop until our value is greater than 10.
#!/bin/bash value=1 until [ ! $value -le 10 ] do echo "$value is not yet greater than 10." ((value=$value+1)) done echo "$value is now greater than 10!"
