I have a makefile, with a test suite target, like so:rcheck:        fooThis shows the output from the foo command on stdout, and returns an exit code from foo which is handled by make as normal.I want to add something to this target, to parse foo's output without affecting the existing behaviour - that is:foo's stdout/stderr should be displayed on stdout/stderr, as beforethe final outcome of the rcheck target, as far as Make is concerned, is whatever foo's exit code wasstdout from foo should be passed to a second command, bar, somehow. bar's exit code doesn't matter, and bar should not output anything to stdout or stderr in addition to 1. above (unless the solution means bar handles 1. itself)What is the neatest solution here?
How can I catch a command exit code for later, in a Makefile?
bash;shell;pipe;make;return status
If you're not worried about the timing of data passing from foo to bar, and you're okay with a tempfile which will need to be handled in your clean target, then simply:rcheck:        foo | tee sometempfile        -bar < sometempfile >/dev/null 2>/dev/nullIf on the other hand you care a lot about timing then you could make bar repeat its input to stdout and try something like:rcheck:        -(foo; echo $$? > sometempfile) | bar        exit $(cat sometempfile)I'm sure there'll be cleaner ways, but the above came to mind.  (Note, both are untested)
