while(1)                             fish                             while(1)


       while - perform a command multiple times

       while CONDITION; COMMANDS...; end

       The while builtin causes fish to continually execute CONDITION and
       execute COMMANDS as long as CONDITION returned with status 0. If
       CONDITION is false on the first time, COMMANDS will not be executed at
       all. Hints: use begin; ...; end for complex conditions; more complex
       control can be achieved with while true containing a break.

       while test -f foo.txt; echo file exists; sleep 10; end

       causes fish to print the line 'file exists' at 10 second intervals as
       long as the file foo.txt exists.
