[gentoo-user] Colorized output when piping to tee

[gentoo-user] Colorized output when piping to tee

Hi there,

I am looking for a way to have a colorized output when piping to tee, e.g.:

    /usr/bin/emerge --ask --update --deep --newuse --tree --verbose @world | tee --append nom.txt

I already tried installing "dev-tcltk/expect" which should actually contain "unbuffer" which can help me out. But there is no unbuffer command.

Am I missing something or is there any other way to do that?

# qfile `which unbuffer`
app-misc/unbuffer (/usr/bin/unbuffer)

unbuffer won't help you there anyway. That only changes when stuff is
written to the pipe.

You're actually looking for:

====
       --color < y | n >
              Enable  or  disable  color  output.   This  option will override
              NOCOLOR (see make.conf(5)) and may also be used to  force  color
              output  when  stdout is not a tty (by default, color is disabled
              unless stdout is a tty).
=====

BTW: if you don't want that colorized output in the log, add

app-text/ansifilter (/usr/bin/ansifilter)

for reading the log.

HTH,

  From "man emerge"

   --color < y | n >
          Enable  or  disable  color  output.   This  option will override
          NOCOLOR (see make.conf(5)) and may also be used to  force  color
          output  when  stdout is not a tty (by default, color is disabled
          unless stdout is a tty).

  So you'd want...

/usr/bin/emerge --color y --ask --update --deep --newuse --tree --verbose @world | tee --append nom.txt

  Insert "--color y" into the command.
