Byobu sets $TERM environment variable
to
screen-bce,
screen.linux, or something beginning with
screen(at least currently in Ubuntu 10.10). And if you have
your bash prompt normally colorized, it probably won't work in byobu without
some changes in ~/.bashrc.
To enable color prompt in boybu find out what's the value of $TERM within
byobu:
$ echo $TERM
screen-bce
Now in ~/.bashrc find lines like
# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in
xterm*) color_prompt=yes;;
and append the following line there:
screen*) color_prompt=yes;;
Then find lines like:
# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*)
PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
and change them to:
# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*|rxvt*|screen*)
PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
Here is my ~/.bashrc:
