Redirect all output to file in Bash [duplicate]
That part is written to stderr, use 2> to redirect it. For example:
foo > stdout.txt 2> stderr.txtor if you want in same file:
foo > allout.txt 2>&1Note: this works in (ba)sh, check your shell for proper syntax
All POSIX operating systems have 3 streams: stdin, stdout, and stderr. stdin is the input, which can accept the stdout or stderr. stdout is the primary output, which is redirected with >, >>, or |. stderr is the error output, which is handled separately so that any exceptions do not get passed to a command or written to a file that it might break; normally, this is sent to a log of some kind, or dumped directly, even when the stdout is redirected. To redirect both to the same place, use:
$command &> /some/file
EDIT: thanks to Zack for pointing out that the above solution is not portable--use instead:
$command > file 2>&1 If you want to silence the error, do:
$command 2> /dev/null
To get the output on the console AND in a file file.txt for example.
make 2>&1 | tee file.txtNote: & (in 2>&1) specifies that 1 is not a file name but a file descriptor.
