Bash prompt

Hi there !
I have a basic simple question I need an answer on.
I have a solaris 9 system where when you telnet as root, we get the "bash-2.05#" prompt.
I have found on my solaris 10 that I had to modify the /etc/passwd for root so that he can also have the bash shell when starting, but the prompt there is like "-bash-3.00#".
So my questions :
- why does it start with a "-" ?
- Wat do I need to do to have the pwd inserted before the "bash" ?
Many Thanks !

Hello,
Please change the shell variable PS1 to get things done.
ex:
-bash-3.00# echo $PS1
\s-\v\$
-bash-3.00#
Thanks,
Sal.

[SOLVED]Bash prompt colors different in console as opposed in terminal

Hi
EDIT: I have solved the problem by copying /etc/skel/.bash_profile to my home directory.
Today i updated the system and the bash prompt is fine in my terminal (KDE Konsole or in Xterm) but not in consoles. For normal user (blue colors) i use this settings in the $HOME/.bashrc file:
PS1='[\e[0;36m\u\e[0m@\e[0;36m\h\e[0m]─[\e[0;33m\w\e[0m]\n└─\$ '
For root (red color) /root/.bashrc:
PS1='[\e[1;31m\u\e[0m@\e[1;31m\h\e[0m]─[\e[0;33m\w\e[0m]\n└─\$ '
Now, if i login in console as a normal user it doesn't display blue color but red as if i was root user. Like i said in xterm or KDE Konsole it looks just fine. The case is that consoles don't use my .bashrc file and use instead /etc/bash.bashrc file: Here is my /etc/bash.bashrc file:
# /etc/bash.bashrc
# If not running interactively, don't do anything
[[ $- != *i* ]] && return
#PS1='[\u@\h \W]\$ '
PS1='[\e[1;31m\u\e[0m@\e[1;31m\h\e[0m]─[\e[0;33m\w\e[0m]\n└─\$ '

Tired of writing your own bash prompt?

I realized a few days ago that I got tired of looking up arcane bash escape sequences just to customize my bash prompt. In the open source fashion, I wrote a gui in pyGTK that will automatically make one for you, if you just pick the things you want from a menu. It's not really done yet and there's still stuff that I need to add to it, but I thought i'd see if anyone around here had any comments, or would find it useful.
Check it out: https://github.com/wisp558/promptool
It's worth noting that I only implemented 3 of the most common bash variables, but I should fix that soon. (and the bold button is broken)

Yeah, I plan to. Other things I'm looking at include a place to select the text color, (It'll use the last color in the prompt), background colors, underlined things and changing the whole textview background (I use a black urxvt, personally). I may even add a thing to save prompts or something. I might add an option to append the PS1 to one's ~/.bashrc, making the gui display the finished prompt rather than the terminal and more! I have plenty of ideas left!
As a note, the escape you posted is just the bold option I already have. There is a high intensity option in bash, which I will look into, although it does nothing in my terminal. Those are things like '\e[0;90m' and its friends.
Thanks for your feedback, guys.

[solved]Gentoo Bash Prompt not working in X

Hi
I'm using this .bashrc from AUR:
http://aur.archlinux.org/packages.php?ID=18418
it is said to be the standard bashrc from gentoo.
It works with xterm, but I now installed urxvt (256 color) and it doesn't work any more, my prompt ist not colored any more.
I'm not familiar with bash scripting, perhaps someone could have a look.
The Problem ist not my .Xdefaults, I tried with an empty one. I also did "source .bashrc".

Bash prompt changed from "macbook-pro" to "fdrs-ipad"

Normally in bash my prompt began "macbook-pro" after trying to use AirDrop it is now "fdrs-ipad". This doesn't seem to have affected anything yet but I am unsure how this happened or what it may do eventually. I googled around to try to find solutions but I couldn't find anyone with a similar problem. Anyone have an idea what happened and how I can change this back?
Thanks!

If that doesn't work, the hostname is being set to the result of a reverse lookup of your IP address on a local DNS server, most likely your gateway.

How to change the bash prompt?

When I open a shell, I get as prompt:
user@myhost:~$
Maybe it comes from my former Debian installation (I kept /home when installing Arch), because:
$ echo $PS1
${debian_chroot:+($debian_chroot)}\u@\h:\w\$
When I su to root, I get:
bash-3.2#
What do I have to do in order to get something like:
root@myhost:/home/user#
Browsing the Internet, I found that it has to do with /etc/profiles, but I did not manage to find out the specific steps.
Thank you.

Well, I renamed .bashrc (in order to keep it as a backup) in my home folder and then I got the bash-3.2$ prompt. For some reason, the PS1 in /etc/profile.bash is not taken.
If I just su, I got bash-3.2#. If I "su -", I got [root@myhost ~]#. Hypothesis: /etc/profile.bash is only observed by the root environment. May this be right?
So I edited the .bashrc that Debian had left, and I had to place it both as /home/user/.bashrc and /root/.bashrc. I copy it at the end. See that I made the prompt coloured when being root.
Still, if I did "su -" or "su username -", or logged-in in text-mode as root, I got the profile that is on /etc/profile.bash So I renamed /etc/profile.bash and copied that same file /root/.bashrc as /etc/profile.bash. I hope not to have committed any insanity , otherwise please let me know.
Thank you.

[SOLVED]Color Bash Prompt help

So I have been customizing my arch box and everything has been great except for one problem; the bash color prompt. I am kind of running a color screen where I am using the same shade of green, blues, grays, etc. I would like to continue that with my bash color prompt. However it seems to use some weird numbering system for its colors that I am not familiar with. I know that there is a way to use 256 colors, but I am not sure how.
So for example I would like to have this shade of green from bash 0;32m' as this #87d75f in html notation.
Is there a way for this to be done? Thanks.

Bash prompt vs Zsh prompt problem [SOLVED]

I have set up my .zshrc and it works perfectly
function bat1()
echo $(( $(awk ' /remaining/ {print $3} ' /proc/acpi/battery/BAT0/state) * 100 / 71590 ))
# 71590 is the capacity of my #1 bat in mWh
function bat2()
echo $(( $(awk ' /remaining/ {print $3} ' /proc/acpi/battery/BAT1/state) * 100 / 46620 ))
# 46620 is the capacity of my #2 bat in mWh
#Right-side zsh promp :
RPROMPT=' $PR_RED$(bat1)/$(bat2)$PR_NO_COLOR'
Each time I get a new prompt(when a command finishes or I simply type <Return>) the battery info is updated.
Now let's consider bash :
Same functions, same way of working :
PS1="$(bat1)/$(bat2) >"
The problem is that bash does not automatically update the battery info. I need to source my .bashrc, which is, of course, a real pain.
Can any bash guru help me to find a solution to make bash work like zsh ?

Try
PS1="$(bat1)/$(bat2) >"

Bash Prompt on Nexus 6001

Anybody seen this or know how to get the switch to boot back into NX-OS? We upgraded a pair of Nexus 6001s to 6.0(2)N2(1)... one came up fine, the other keeps coming up to a BASH-3.2# prompt and we appear to have full root access.
I'm guessing this is not normal behavior but I'm trying to see if anybody has seen this while we get TAC on it. I attached a screenshot for your viewing pleasure.
Thanks.

Hello,
I am from TAC. you are hitting a bug. CSCuh28244
Symptom:
Nexus 6000 might experience unexpected reload when the switch is getting booted up after being upgraded using
install all
command. It will take a long time for the switch to boot up. Instead of booting all the way, the console will boot in bash mode. Eventually the switch would experience a crash.
Conditions:
Issue happens after upgrading switch from
6.0(2)N1(2)
to
6.0(2)N2(1)
and when using
install all
command to upgrade.
Workaround:
power cycle the switch to restore services.
Thanks,
Richard

[Solved] Change bash prompt listing in terminal

Hi,
I've always used c-shell for ease in writing shell scripts. I'm interested in moving to bash and just using c-shell for scripting.
In a .cshrc I can do something like this:
if [ -o /bin/su ]; then
set prompt="%{\e]2\;%t - %m:%/^g\e]1\;%m^g\r%}%B:%m%b# "
else
set prompt="%{\e]2\;%t - %m:%/^g\e]1\;%m^g\r%}%B:%m%b$ "
fi
I edited the if statement for what an if statement should look like in bash. This, however, doesn't work. I'm assuming the word "prompt" is wrong. How do I get this working in bash?
EDIT: SEEMS LIKE THIS DID IT!
PS1="\u@\h:\w#
Last edited by playdafunkimuzic (2009-08-27 18:29:51)

export PS1="whatever" is the way to set the prompt in bash. not sure bout that -o are you checking for root? if so, [ $(id -u) -iq 0 ] returns true for root.

::SOLVED:: change bash prompt while in ssh

I'm learning how to use bash bit by bit, but came up with a question I'm not certain how to solve. I learned some time ago about setting the PS1 variable to customize the shell prompt, and have a nice prompt I like using. However, it would be nice to have the prompt be flagged if I'm logged in through ssh as opposed to directly on the computer itself. How could I do this?
One thought I had was to check to see if certain environment variables exist (eg. $SSH_CONNECTION).
Doing if [ $SSH_CONNECTION ]; then ... fi gives an error about too many arguments. None of the other SSH related variables seem to be just a number value. Is there a way to test for the existence of a variable in bash?

Color Bash prompt Wiki needs editing [SOLVED]

Howdy archers
I didn't know where else or who I should contact for this....
but I found something that "may" need editing on this part of the wiki http://wiki.archlinux.org/index.php/Color_Bash_Prompt
the part where it says * Edit root's Bash file; copy it from /etc/skel if the file is not present:
# nano /root/.bash_profile
I tried this over and over again with no luck... then I figured out that the info on the wiki was incorrect... you are not suppose
copy ".bash_profile" to /root you are suppose to copy ".bashrc" over to /root and add what you want in it... otherwise
no changes take effect
cheers

Bash prompt delay

Hi there.
I'm having a problem with a delay right after logging into the virtual terminal. I type the username and password, see the 'last logged in at...' message...and then I get nothing for about 15 seconds. It only happens on the first login and only happens on my user account (the other being root). I've tried to duplicate the problem with bash -lv to no avail. htop doesn't give any above average CPU usage and I don't see any disk activity.
Any ideas? Something else to try?
Thanks.

It took some trickery, but I found out a way to debug this. Create a file somewhere (eg /bash-verbose) and make it executable. Put the following contents in it:
exec /bin/bash -v
Now modify your /etc/passwd and change /bin/bash for your user and replace /bin/bash at the end of line, with the path to the script created above. This way you will get a verbose bash login shell which should tell you what your waiting for. Would you like even more info you could strace the bash process as well.

[SOLVED] Color Bash Prompt - Arch Latest News w/o description

Hi everybody, i'm trying to get the Arch Latest News in the bash profile when terminal starts. I followed the wiki https://wiki.archlinux.org/index.php/Co … s_at_logon and I can show the latest news without problems.

I tried to figure out what lines I should delete in the /etc/bash.bashrc file but.. you know the sintax is pretty obscure for the most of us (at least for me). I see that there is a description line.. but, really I can't manage this. How can I do this? Thanks in advance.

Magic Bash Prompt

This magical prompt will cycle through the colors of the rainbow! It'll work properly if your terminal follows ANSI colors. (i.e. it works on the Linux console)
UPDATE: Version 1.0.0 released! Includes new random_hue function for random colors!
In your .bashrc file:
# Magic Prompt 1.0.0
function next_hue
color=$((31 + (++color % 7))) # set 31 to 30 for dark on light
PS1="\[\e[1;${color}m\]\\$ $reset" # set 1 to 0 for dark on light
function random_hue
color=$(($RANDOM % 7 + 31)) # set 31 to 30 for dark on light
PS1="\[\e[1;${color}m\]\\$ $reset" # set 1 to 0 for dark on light
PROMPT_COMMAND="random_hue"
Try it out, and comment out your old PS1. It's cool if you hold down the return key.

Hillarious waste of the PROMPT_COMMAND, but still hillarious. @drcouzelis: no, sadly this isn't something you can really get around. ZSH offers the ability to specify multiple precmd hooks.
I've condensed it into pure awesome:
next_hue() {
color=$(( 30 + (++color % 8) ))
echo -ne "\e[1;${color}m" # change 1 to 0 for darker colors
PROMPT_COMMAND=next_hue
PS1="\$\[\e[0m\] "
