Running processes in sequence
Normally, if you type a command at the Unix prompt, that command runs to completion, and then when it is finished, you get another Unix prompt.
To execute multiple commands in sequence, place the commands on the same line, separated by semicolon (";") characters:
% insult_waiter;wake_up_neighbor;wreck_carUnix will execute the
insult_waitercommand first. When that is done, the
wake_up_neighborcommand will be run. When that finishes, the
wreck_carprocess will be run, and then you will get another command prompt.
Note that you can redirect the input and output for a whole sequence of processes at once by grouping the commands in parentheses. For example, the command
% (insult_waiter;wake_up_neighbor;wreck_car) >twit.outwould cause the standard output for all three processes to be redirected to file
