My Bash Prompt

In bash there are several shortcuts you can use. My prompt looks like this:

PS1="[\u@\h \w]\$ "

which produces
[username@server workingdir]$

You can add color to them as well. There are a number of variables you may use in bash.

\a Alarm (Bell)
\d Date in fomat "Wed Jun 21"
\h Hostname
\j Jobs (Number of Background jobs)
\l Current Terminal Name
\n Newline inserted into prompt. (Usefull for 2-line prompts)
\r Carriage return in prompt
\s Current Shell
\t Time in 24 hour format, 16:25:00
\T Time in 12 hour format, 04:25:00
\u User's account name
\v Version and release of bash
\w Current working directory (full path /home/bill/.mozilla)
\W Last element of Working directory (.mozilla)
\V Version, release and patch level of bash
\\ single backslash inserted into prompt
\! Number of current command in command history
\# Number of current command where numbers start at 1 when shell starts
\A Time in 24 hour format without seconds 16:25
\@ Time in 12 hour format without seconds, 04:25 p.m.
\$ indicates root. display $ when not root and # when root.
\[ starts a sequence of non printing characters ending with \] (explanation to follow)
\nnn the character in ascii set coresponding to the octal number nnn

The last two commands can add color to the prompt. For example,

\[\033[1;36m\] changes the color to a light blue. \[\033[0m\] changes it to back to off-white. On a standard black background, white letters I use
PS1="[\[\033[1;36m\]\u\[\033[0m\]@\[\033[1;35m\]\h \[\033[1;32m\]\w\[\033[0m\]]\$ "
which gives me
[bill@server /usr/local/bin]$

The color changes are confusing, I know, but I like it.

oclock

OCLOCK(1)						      General Commands Manual							 OCLOCK(1)

NAME

       oclock - round X clock

SYNOPSIS

       oclock [-option ... ]

DESCRIPTION

       Oclock simply displays the current time on an analog display.

OPTIONS

       -fg color
	       choose a different color for the both hands and the jewel of the clock

       -bg color
	       choose a different color for the background.

       -jewel color
	       choose a different color for the jewel on the clock.

       -minute color
	       choose a different color for the minute hand of the clock.

       -hour color
	       choose a different color for the hour hand of the clock.

       -backing { WhenMapped Always NotUseful }
	       selects an appropriate level of backing store.

       -geometry geometry
	       define the initial window geometry; see X(7).

       -display display
	       specify the display to use; see X(7).

       -bd color
	       choose a different color for the window border.

       -bw width
	       choose  a  different width for the window border.  As the Clock widget changes its border around quite a bit, this is most usefully
	       set to zero.

       -shape  causes the clock to use the Shape extension to create an oval window.  This is the default unless the shapeWindow resource  is  set
	       to false.

       -noshape
	       causes the clock to not reshape itself and ancestors to exactly fit the outline of the clock.

       -transparent
	       causes the clock to consist only of the jewel, the hands, and the border.

COLORS

       If you would like your clock to be viewable in color, include the following in the #ifdef COLOR section you read with xrdb:

       *customization:		       -color

       This  will  cause  oclock to pick up the colors in the app-defaults color customization file: /usr/lib/X11/app-defaults/Clock-color.  Below
       are the default colors:

       Clock*Background: grey
       Clock*BorderColor: light blue
       Clock*hour: yellow
       Clock*jewel: yellow
       Clock*minute: yellow
