to run all shells in xterm as login shells you can also put this into your ~/.Xresources file:
| Code: |
XTerm*loginShell: true

Can anyone help me combine two prompts? I'm a newbie at this... I looked over some bash scripting guides... which help with loops, and variables... but these prompts seem to use numbers that indicate something I can't quite figure out.
I want to use this one:
| Code: | | PS1='\n\[\033[32m\]\w\n\[\033[0m\][\[\033[1;31m\]\u@\h \[\033[1;34m\]$(/usr/bin/tty | /bin/sed -e '\''s:/dev/::'\'')\[\033[0m\]] \[\033[0m\]' |
Which is this:
| Quote: | /usr/portage
[user@hostname pty/s0] |
But then I want to use the APM Battery one (I'm on a laptop)
| Code: | | PS1="\[\033[01;3\`apm|awk '\$2~/on-line/{print "2"; exit}\$5~/high/{print "3"}\$5~/low/{print "1"}'\`m\]\`apm|awk '\$5~/%/{print \$5}\$6~/%/{print \$6}'\` \[\033[01;31m\]\u@\h \[\033[01;34m\]\W \$ \[\033[00m\]" |
Which is this:
| Quote: | | 100% user@hostname directory $ |
...
What I would like to do is make it like this:
| Quote: | /usr/portage
100% user@hostname pty/s0 |
Thanks in advance! |

why are ppl using \033 for the escape sequence character, when they can simply do a \e???
yields
is the general setup stripped of all colors.... the hostname is green for users and red for root. the []'s are dark red... and yeah.. i use \e instead of \033 when i start my color codes... hehe...
btw.. is there a reason why i should do \033 instead of \e???

| Code: | | export PS1="\[\033[01:32m\][\e7\e[0;71H\@\e8\]\[\033[01;3\`apm|awk '\$2~/on-line/{print "2"; exit}\$5~/high/{print "3"}\$5~/low/{print "1"}'\`m\]\`apm|awk '\$5~/%/{print \$5}\$6~/%/{print \$6}'\` \[\033[01;31m\]\u@\h \[\033[01;34m\]\W \$ \[\033[00m\]" |
The above is my code for my root user. It gives the time in thetop right corner and the prompt itself looks like
| Quote: |
[100%root@psalmsswells $ |
I was wondering...how do I either add a closing ] to the power indicator (yes it's a lappie) or remove the initial one?
I'm not hugely experienced in shell scripting...what I have there was pasted together from a few of the ones previously.
Thanks!

Sure, you can use the normal grep/sed/cat/awk/etc tools on any of the files or directories in the /proc filesystem. fx; if you want the prompt to show the number of running processes and the amount of memory available, you could set PS1 to:
| Code: | | export PS1="[$(find /proc -type d -regex '/proc/[0-9]+' -maxdepth 1 | wc | awk '{print $2}'):$(grep 'MemTotal' /proc/meminfo | awk '{print $2}')Kb] \$" |
Not a particularly useful prompt, but it should get the point across. On my system it shows:
For 84 active processes, and almost 8Mb free (damn  )

Nice clock code! Filing that one away. You can add a close ] after the power meter by adding one after the final call to apm/awk...right after "{print \$6}'\`" should do it. If you want the remove the opening bracket, I'm guessing it the one right before the "\e7".

Yep...anywhere in there will do. |

Nice thread.
How do I get the CWD to be just the directory your in without the leading path. i.e. /usr/src/linux shows only linux. (default prompt)?
Thanks.

Here's my RGB (red green blue) bash prompt.
| Code: |
#!/bin/bash
#you need a vga font to use this bash prompt
if [ "$UID" -ne "0" ];then
U=$
else
U=#
fi
function rgb {
local CLEAR="\[\033[0m\]"
local RED="\[\033[00;30;41m\]"
local GREEN="\[\033[00;30;42m\]"
local BLUE="\[\033[00;30;44m\]"
local GRAD1="\[\333\262\261\260\]"
local GRAD2="\[\260\261\262\333\]"
local EXIT='echo $?'
PS1="$RED$GRAD1[User: \u@\h]$GRAD2$GREEN$GRAD1[ExitStatus: `$EXIT`]$GRAD2$BLUE$GRAD1[Time: \$(date +%H%M)]$GRAD2$CLEAR\n\W $U> "
}
|
Here's how to use it: source rgb.sh && rgb. It's basically three gradient separated "boxes" (first one is red, second green, third blue) with user@hostname, ExitStatus and time. You need a vga font (for the gradient): http://home.earthlink.net/~us5zahns/enl/ansifont.html |

My prompt looks like this:
| Quote: | | localhost:../linux/Documentation $ |
Notice the path has been truncated from the front? This stops it taking up more of the command line than I'd like when I'm deep inside a directory tree.
Here's the bit of magic in my .bashrc that does this:
| Code: | function shorten_pwd
{
# change this to suit your taste
pwd_length=20
DIR=`pwd`
echo $DIR | /bin/grep "^$HOME" >> /dev/null
if [ $? -eq 0 ]
then
CURRDIR=`echo $DIR | awk -F$HOME '{print $2}'`
newPWD="~$CURRDIR"
if [ $(echo -n $newPWD | wc -c | tr -d " ") -gt $pwd_length ]
then
newPWD="~/..$(echo -n $PWD | sed -e "s/.*\(.\{$pwd_length\}\)/\1/")"
fi
elif [ "$DIR" = "$HOME" ]
then
newPWD="~"
elif [ $(echo -n $PWD | wc -c | tr -d " ") -gt $pwd_length ]
then
newPWD="..$(echo -n $PWD | sed -e "s/.*\(.\{$pwd_length\}\)/\1/")"
else
newPWD="$(echo -n $PWD)"
fi
make_prompt
echo $PWD > ~/.pwd
}
PROMPT_COMMAND=shorten_pwd |
Then elsewhere in PS1 I just use $newPWD rather than the working directory switch.
Full credit to whoever gave me this - I do not recall the source. |

ok, i wrote another method for shortening the pwd that seems simpler to me than the method above and can be put directly into the PS1 assignment.
put this where you want the pwd to appear:
| Code: | | \$(pwd | sed 's=\(.*\)\(.\{25\}\)$=\1...\2=' | sed 's=^\.\.\.\|.*\(\.\.\.\)=\1=') |
the first sed inserts a '...' at the number of characters from the end that you specify. here i have used the value 25, you can change that to whatever you like.
the second sed either removes the '...' if they occur at the beginning of the string (meaning that the pwd is already shorter than then number of characters you specified, so take out the '...'), or it removes everything before the '...' in the case where the pwd is longer than the number of characters you specified.
(please let me know if you find any error in the code above, or have a better way to do the same thing)
here are my prompts, using a few of the colors and tips mentioned on the first page of this thread and the code from above (i use green on a black background):
| Code: | PS1="\n$PRPL\d, \@: $NONE\$(pwd | sed 's=\(.*\)\(.\{25\}\)$=\1...\2=' | sed 's=^\.\.\.\|.*\(\.\.\.\)=\1='): \[\033[1;36m\]\$(/bin/ls -1 | /usr/bin/wc -l | /bin/sed 's: ::g') files, $YEL\$(/bin/ls -lah | /bin/grep -m 1 total | /bin/sed 's/total //')b\n$HBLU\u$WHT@$HBLU\h$NONE $HBLU#$NONE "
PS2="$HBLU\u$WHT@$HBLU\h$NONE $HBLU>$NONE " |
which look something like this:
| Quote: | Fri Nov 07, 02:20 PM: /home/gdub/websites: 19 files, 107Kb
gdub@nebuchadnezzar # if
gdub@nebuchadnezzar > |
note: the '@' is white
and when the pwd is longer than what you specify:
| Quote: | Fri Nov 07, 02:20 PM: ...bsites/images/backgrounds: 19 files, 107Kb
gdub@nebuchadnezzar # |
i think next i will write something where it will trucate the pwd in the middle instead of at the beginning |

try this on for size, this will truncate the pwd in the middle, just specify how many characters you want to see in the front and how many you want to see at the back. if the pwd is shorter than the sum, then the entire pwd is printed: | Code: | | \$(pwd | sed 's=^\(.\{5\}\)\(.*\)\(.\{15\}\)$=\1...\2...\3=' | sed 's=\.\.\.\.\.\.==' | sed 's=\(.*\)\.\.\..*\.\.\.\(.*\)=\1...\2=') |
in this case it would display 5 characters in the front and 15 in the back.
with the pwd being | Code: | | /home/gdub/websites/images/backgrounds |
here are some examples of what it would look like:
with 5 in front and 15 in back: | Code: | | /home...ges/backgrounds |
with 20 in front and 10 in back: | Code: | | /home/gdub/websites/...ackgrounds |
with 0 in front and 8 in back:
and finally, with 20 in front and 20 in back: | Code: | | /home/gdub/websites/images/backgrounds |

another nifty trick for the codes above, if you would like to have your home directory displayed as ~ instead, you can pipe this between the pwd and the first sed | Code: | | sed "s=`echo $HOME | sed 's:\/:\\\/:g'`=~=" |
for a final command of | Code: | | \$(pwd | sed "s=`echo $HOME | sed 's:\/:\\\/:g'`=~=" | sed 's=^\(.\{5\}\)\(.*\)\(.\{15\}\)$=\1...\2...\3=' | sed 's=\.\.\.\.\.\.==' | sed 's=\(.*\)\.\.\..*\.\.\.\(.*\)=\1...\2=') |
this will turn the above into something like this | Code: | | ~/web...ges/backgrounds |

and of course, I start my xterm with

which will produce this sexy and informative prompt

blink is supposed to be:
set on: \033[5m
set off: \033[25m
but on my box it doesn't work...it just makes the background color medium grey. suck! see 'man 4 console_codes' for the rest of the codes.

NEWBIE ALERT!
I would like to change my prompt. I have read some of this thread but does not change when I change the .bashrc file. This is the one that is in /home/dale. It is the only one I could find. There is none in /root. This is the file.
| Code: | # /etc/skel/.bashrc:
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/skel/.bashrc,v 1.8 2003/02/28 15:45:35 azarah Exp $
# This file is sourced by all *interactive* bash shells on startup. This
# file *should generate no output* or it will break the scp and rcp commands.
# colors for ls, etc.
eval `dircolors -b /etc/DIR_COLORS`
alias d="ls --color"
alias ls="ls --color=auto"
alias ll="ls --color -l"
PS1="\n\[\033[35m\]\$(/bin/date)\n\[\033[32m\]\w\n\[\033[1;31m\]\u@\h: \[\033[1;34m\]\$(/usr/bin/tty | /bin/sed -e 's:/dev/::'): \[\033[1;36m\]\$(/bin/ls -1 | /usr/bin/wc -l | /bin/sed 's: ::g') files \[\033[1;33m\]\$(/bin/ls -lah | /bin/grep -m 1 total | /bin/sed 's/total //')b\[\033[0m\] -> \[\033[0m\]"

;;

PROMPT_COMMAND='echo -ne "\033_${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~}\033\\"'
;;
esac
##uncomment the following to activate bash-completion:
[ -f /etc/profile.d/bash-completion ] && source /etc/profile.d/bash-completion
|
I pasted the PS1 line in there but there is no change. I thought that one was kind of neat.
What am I doing wrong, wrong file maybe? I am trying to change the Konsole that I use in KDE. Will this also change the normal command line prompt, one that is not inside a GUI? Ya know like the one that you get when you are installing Gentoo.
Thanks in advance for the help.

Of course you are aware that simply adding a line that says "PROMPT *[$V] $P*" in your AUTOEXEC.BAT file on any MS system will do the same, right?
