Question

my dev workflow is something like this:

term-1 $ ctl-C #kills tail
term-1 $ catalina7 stop
term-2 $ ant
term-1 $ catalina jpda start && tail -f logs/catalina.out

how can i hook the ^C on tail, to run catalina stop?

Answer 1

You can put this in a bash script and use the built-in trap command like this:

trap "catalina stop" INT
ant
catalina jdpa start && tail -f logs/catalina.out

The first argument to trap is a command that is to be run when the given signal (the second parameter) is received. To trap Ctrl-C you use the INT signal. Another useful signal is EXIT which calls the trap every time the script ends.
