How to buld with MAKE and only --silent output on screen, but get full output to log file

Question

How can I redirect output from MAKE i such a way that I get only --silent output to screen, but full MAKE-output to a log file?

Or can this be achieved through some sdout/stderr redirection magic?

I don't think I understand your question fully. Doesn't 'make > log' work well enough?
I do not think that's a good question... if you want full output to the file, then use make > file.log 2>&1 and you'ill get a "--silent" output to screen. This is a very basic shell usage.

make > log-file 2>&1

or

make 2>&1 | tee log-file | filter

Where filter is a program that passes only what you want to see. Use grep or sed or something else.

	+1 I hadn't run across tee before. Thanks! – David Oneill Mar 23 '11 at 16:18
	to @David Oneill On linux you can also do `make \| tee /dev/stderr \| filter > filtered-log` this does the opposite. But /dev/stderr, /dev/stdout, /dev/stdin, /dev/fd/* is not available on all systems. – richard Mar 23 '11 at 17:12

This was answered before with a comment:

if you want full output to the file, then use make > file.log 2>&1 and you'ill get a "--silent" output to screen. This is a very basic shell usage.

and 4 days have passed, i think that it no longer need to be responded.

	That's not what the question requested, though. `make --silent` doesn't print the commands as they are executed (as if they were all prefixed by `@`), but you still get their output. – Gilles Mar 23 '11 at 21:12
	1st: The other answer was just a copy of the command 2nd: I was very clear in saying "if you want full* output to the file", requesting edition for and you'ill get a "--silent" output to screen* would be better since my comment has 2 'great comment' votes and a request to put it as answer. What we want are answers, so try to help. – D4RIO Mar 23 '11 at 22:10
	It seemed a bit harsh to vote this down. It was already a comment, before I added my answer. My answer just is an incremental improvement. It does not deserve a negative score, so I bumped it back up to 0. – richard Mar 24 '11 at 9:19
