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? Commented Mar 19, 2011 at 16:03

    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. Commented Mar 19, 2011 at 16:36

Reset to default

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.

  • 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. Commented Mar 23, 2011 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. Commented Mar 23, 2011 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. Commented Mar 23, 2011 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. Commented Mar 24, 2011 at 9:19
