while(1) fish while(1)
NAME
while - perform a command multiple times Synopsis while CONDITION; COMMANDS...; end Description 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. Example 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.
