 Posted: Tue Oct 31, 2006 5:40 am Post subject: terminal question |
 |
|
so ive been searching the forums and gentoo-wiki for the last 45 mins and i KNOW its on here somewhere, bc thats where i found it last time, but whats the link so that i can change my terminal to show the entire path in console
eg: instead of
it would say something like | Quote: | | root@BlackBeauty: /home/sinister |
and reg user would be | Quote: | | sinister@BlackBeauty: /home/sinister/ |

your answer can easily be deduced from the PS1 environment variable, affectionately known by myself as "that variable that affects the look of the prompt". What do you want to bet there's a better name out there somewhere? But i don't want to spend 45 minutes looking for that.
anyways, running "echo $PS1" as regular user give us
| Code: | dan@descartes ~ $ echo $PS1
\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\]
dan@descartes ~ $ cd /usr/src/linux
dan@descartes /usr/src/linux $ |
and as you can see, we get the full path. but for root...
| Code: | \[\033[01;31m\]\h\[\033[01;34m\] \W \$\[\033[00m\]
descartes ~ # cd /usr/src/linux
descartes linux # |
as you can see, you need to change that uppercase W to a lowercase w. the easiest way to do this for root would probably set it in /root/.bashrc by appending this:
| Code: |
export PS1="\[\033[01;33m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\]"
|
now here's a question: what are all the \[\033[01;33m\] things? I know they must be some kind of escape code for the terminal (at least i am guessing the terminal's what gets it) because
1) they're too obscure to have anything to do with anything recent, but terminal standards are ancient ; and
2) they work at the virtual console and in xterm.
or maybe the'yre for bash. anyway, i know the last number can be set to one of the 16 "original" colors (you know the ones i mean) but which code is which is kind of odd. and i think the 01; part is telling it to go bold on that as well. but i haven't experimented to recently or soberly, so your results may vary.
anyway, there's your answer, as well as some of my own musings. enjoy!

The reference you seek is likely man 1 bash or man 1 ksh or man 1 tcsh.
Given bash as the shell, export PS1="\u@\H \w \$" would be what you are asking for, so long as you do not seek color.

Perhaps "prompt string 1"?
As for the supposition on the escape sequences, good guess. You might find this excerpt from bash(1) elucidating.
| Quote: | \[
begin a sequence of non-printing characters, which could be used to embed a terminal control sequence into the prompt
\]
end a sequence of non-printing characters |

If you actually see "localhost", you probably need to edit /etc/conf.d/hostname

I guess what you want is:
| Code: | | PS1='\[\033[01;32m\]\u@\h:\[\033[01;34m\]$PWD \$\[\033[00m\] ' |
in /root/.bashrc and /home/yourusername/.bashrc
make sure you replace or put it after any other PS1 lines.
Alternatively, put it in /etc/bash/bashrc if you want this to affect all users, but note that new versions of baselayout will want to replace this file later, so you have to preserve your changes across config file updates (with etc-update or dispatch-conf, etc).
---
Here's the .bashrc prompt stuff I've been using for about 2 years, in case it interests you:
| Code: | ######### COLOR PROMPT SECTION ##########
# Set colorful PS1 only on colorful terminals.
# dircolors --print-database uses its own built-in database
# instead of using /etc/DIR_COLORS. Try to use the external file
# first to take advantage of user additions.
# use_color=false
#safe_term=${TERM//[^[:alnum:]]/.} # sanitize TERM
#
#if [[ -f /etc/DIR_COLORS ]]; then
# grep -q "^TERM ${safe_term}" /etc/DIR_COLORS && use_color=true
#elif [ -x /usr/bin/dircolors ] && dircolors --print-database | grep -q "^TERM ${safe_term}"; then
# use_color=true
#fi
# brashly override the above since most things seem to support colors these days,
# including BSD which the above linux-centric checks will not detect.
use_color=true
if ${use_color}; then
PHOST="${HOSTNAME%%.*}"
if [[ "$EUID" == 0 ]]; then # root user -> red all uppercase HOSTNAME
# PHOST = pre-formatted, DHOST = colorized
PHOST="$(echo ${HOSTNAME%%.*} | tr '[:lower:]' '[:upper:]')"
DHOST="\[\033[01;31m\]${PHOST}"
PS1="${DHOST} \[\033[01;34m\]\${PWD/\$HOME/~} # \[\033[00m\]"
else if [[ "$EUID" == 1000 ]]||[[ "$USER" == "dlareh" ]]||[[ "$USER" == "lare" ]]; then
# main user -> green regular case hostname
DHOST="\[\033[01;32m\]${HOSTNAME%%.*}"
else # some other user -> yellow/orangeish regular case hostname
DHOST="\[\033[01;33m\]${HOSTNAME%%.*}"
fi
PS1="${DHOST} \[\033[01;34m\]\${PWD/\$HOME/~} \$ \[\033[00m\]"
fi
else # we don't have colors
if [[ $EUID == 0 ]]; then
PS1='root@${HOSTNAME} $PWD # '
else
PS1='${USER}@${HOSTNAME} ${PWD##*/} \$ '
fi
fi
######### END COLOR PS1 STUFF #########
PROMPT_COMMAND=_setprompt
function _setprompt {
wintitle "${PHOST}:${PWD/#$HOME/~}"
}
function wintitle {
# Change the window title of screens and xterms
case $TERM in
