Regarding the bash 3/2000 man page, the "list" on lines 4 and 8 isn't
clear if it refers to the "do list", or the first "list":
1 while list; do list; done
2 until list; do list; done
3 The while command continuously executes the do list
4 as long as the last command in list returns an exit
5 status of zero. The until command is identical to
6 the while command, except that the test is negated;
7 the do list is executed as long as the last command
8 in list returns a non-zero exit status. The exit
9 status of the while and until commands is the exit
10 status of the last do list command executed, or
11 zero if none was executed.
Sure, two seconds of thought give the answer, but lets make it idiot proof.
