make-first-existing-target - runs make on one of several targets


make-first-existing-target [-c cmd] target1 [target2 ...] -- [make-options]


The design of make(1) causes difficulty when you know that a Makefile probably has one of
several standardized target names, and want build machinery to run exactly one of them,
propagating any errors. make(1) will exit 2 if a target does not exist, but an existing
target may also exit 2 due to some other failure. Makefiles cannot be reliably parsed to
find targets by anything less Turing-complete than make, and make itself does not provide
a way to enumerate the targets in a Makefile. It may not even be possible to enumerate the
targets in a Makefile without executing part of it. (Proof of this is left as an exercise
for the reader.)

This program avoids the problems described above, by attempting to call each specified
target in turn, until it observes make actually doing something for one of them.


-c cmd
This can be used to specify the make command to run. Default is "make".


The exit status is 0 if at least one target existed and was successfully run, and nonzero
