# The until loop
|
||
|
|
|
||
|
|
## Synopsis
|
||
|
|
|
||
|
|
until <LIST1> ; do
|
||
|
|
<LIST2>
|
||
|
|
done
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
The until-loop is relatively simple in what it does: it executes the
|
||
|
|
[command list](/syntax/basicgrammar#lists) `<LIST1>` and if the exit
|
||
|
|
code of it was **not** 0 (FALSE) it executes `<LIST2>`. This happens
|
||
|
|
again and again until `<LIST1>` returns TRUE.
|
||
|
|
|
||
|
|
This is exactly the opposite of the [while
|
||
|
|
loop](/syntax/ccmd/while_loop).
|
||
|
|
|
||
|
|
:!: Like all loops (both `for`-loops, `while` and `until`), this loop
|
||
|
|
can be
|
||
|
|
|
||
|
|
- terminated (broken) by the `break` command, optionally as `break N`
|
||
|
|
to break `N` levels of nested loops
|
||
|
|
- forced to immediately do the next iteration using the `continue`
|
||
|
|
command, optionally as `continue N` analog to `break N`
|
||
|
|
|
||
|
|
### Return status
|
||
|
|
|
||
|
|
The return status is the one of the last command executed in `<LIST2>`,
|
||
|
|
or `0` (`TRUE`) if none was executed.
|
||
|
|
|
