[gentoo-user] redirect

[James Lockie]

How do I redirect the error from an emerge?
I did 'emerge system 2>&1 >t' and that does most of it but it misses the 
actual error message.
'gpm -m /dev/psaux' fails to open null or I would copy the output to a file.
I did a new install and it is failing to emerge glibc.
gpm used to work on this computer in the previous installation.

Set PORT_LOGDIR in /etc/make.conf. The directory you set it to must exist
and be writable by portage.

2>&1 >foo is the wrong syntax for what you want.  This first copies
stderr to stdout, and the second part redirects stdout to a file, but
stderr is still going to the file descriptor that stdout originally
refered to.  It is logically the equivalent of:

stdout=1
stderr=2
stderr=$stdout
stdout=foo
echo $stderr

The correct syntax is ">foo 2>&1", which does the logical equivalent of:

stdout=1
stderr=2
stdout=foo
stderr=$stdout

There's also the shortcut of "&>foo" if you want to redirect stdout and
stderr to the same place.

Nothing is foolproof to a sufficiently talented fool.
