I'm guessing you're talking about the shell prompt. Assuming that shell
is bash, you can read all about it in the bash (1) manpage or the bash
info pages. What you want to look for is the information on PROMPTING,
and set the PS1 variable accordingly. FWIW, I have a quite complicated
multi-color three-line prompt here (fg=foreground color, bg=background
The first line is blank (a simple linefeed char)
Second line as a normal user:
fg:yel red grn gry yel red cyn
bg:blu blk blk blk blk blk blk
username@host tty 24H-time history# #bg-jobs exit-status pwd
That typically leaves enough room for a full path
Third line as normal user (very short, three chars)
If I'm root, the first bits of both lines become yellow on red instead of
yellow on blue, the username changes to root of course, and the first
char of line three changes to a # instead of $, so it's very hard to miss
that I'm running as root, especially with the blue changing to red!
To do that, I use ANSI-term color-codes and the standard prompt escapes
as explained in the bash infopages or manpage. Here's what I have PS1
set to, as displayed by "echo $PS1" (this is as a normal user, as root,
the color-codes would be slightly different, I have logic for that in my
shell startup scripts) :
\] \[\033[00;01;32;40m\]\t\[\033[00m\] \[\033[00;01;30;40m\]#\!\[\033[00m
\] \[\033[00;01;33;40m\]j\j\[\033[00m\] \[\033[00;01;31;40m\]s$?\[\033[00m
\] \[\033[00;01;36;40m\]\w\[\033[00m\] \n\[\033[00;01;33;44m\]\$>>\[\033
Meanwhile, excerpts from the manpage to help decode the above:
(Under Shell Variables)
PROMPT_DIRTRIM If set to a number greater than zero, the value is used
as the number of trailing directory components to retain when expanding
the \w and \W prompt string escapes (see PROMPTING below). Characters
removed are replaced with an ellipsis.
PS1 The value of this parameter is expanded (see PROMPTING below)
and used as the primary prompt string. The default value is ``\s-\v\$ ''.
When executing interactively, bash displays the primary prompt PS1 when
it is ready to read a command, and the secondary prompt PS2 when it needs
more input to complete a command. Bash allows these prompt strings to
be customized by inserting a number of backslash-escaped special
characters that are decoded as follows:
\h the hostname up to the first `.'
\j the number of jobs currently managed by the shell
\l the basename of the shell's terminal device name
\t the current time in 24-hour HH:MM:SS format
\u the username of the current user
\w the current working directory, with $HOME abbreviated with
a tilde (uses the value of the PROMPT_DIRTRIM variable)
\W the basename of the current working directory,
with $HOME abbreviated with a tilde
\! the history number of this command
\$ if the effective UID is 0, a #, otherwise a $
\nnn the character corresponding to the octal number nnn
\[ begin a sequence of non-printing characters, which could
be used to embed a terminal control sequence into the prompt
\] end a sequence of non-printing characters
(There's a few others. That's the ones I use, plus \W since it's of
Looks like your distro sets...
You could replace that with...
Or, to get something between the two, keep the first version and just
... or whatever.
FWIW, if you'd like something even fancier than mine (which is still
pretty basic, really, sticking to the originally available prompt-string
substitutions plus ANSI-color), consider googling...
bash prompt ps1
As with about anything on the net, there's quite a bit of info out there
to help, free for the googling! =:^)
