Apple Right justify for bash

Hi fpmurphy,

Many thanks for the suggestion and your prompt reply. I did find a few resources on the web which may benefit people using the terminal.

These are below:

8 Useful and Interesting Bash Prompts

and

Add a Separator & Time Stamp Between Terminal Commands to Increase Readability

I than mixed the codes I found on these sites together to make something below:

Code:
 Fill with minuses
# (this is recalculated every time the prompt is shown in function prompt_command):

fill="--- "
reset_style='\[\033[00m\]'
status_style=$reset_style'\[\033[0;90m\]' # gray color; use 0;37m for lighter color
prompt_style=$reset_style
command_style=$reset_style'\[\033[1;29m\]' # bold black

# Prompt variable:

#PS1="$status_style"'$fill \t\n'"$prompt_style"'${debian_chroot:+($debian_chroot)}\u@\h:\w\$'"$command_style "
PS1='\n\[\e[32;1m\](\[\e[37;1m\]\u\[\e[32;1m\])-(\[\e[37;1m\]jobs:\j\[\e[32;1m\])-(\[\e[37;1m\]\w\[\e[32;1m\])$fill (\t)\n(\[\[\e[37;1m\]! \!\[\e[32;1m\])-> \[\e[0m\]`if [ $? = 0 ]; then echo \[\e[33m\]^_^\[\e[0m\]; else echo \[\e[31m\]O_O\[\e[0m\]; f$

# Reset color for command output
# (this one is invoked every time before a command is executed):

trap 'echo -ne "\033[00m"' DEBUG

function prompt_command {

        # create a $fill of all screen width minus the time string and a space:

        let fillsize=${COLUMNS}-32
        fill=""

        while [ "$fillsize" -gt "0" ]

        do

                fill="-${fill}" # fill with underscores to work on
                let fillsize=${fillsize}-1

        done

        # If this is an xterm set the title to user@host:dir

        case "$TERM" in

                xterm*|rxvt*)
                bname=`basename "${PWD/$HOME/~}"`
                echo -ne "\033]0;${bname}: ${USER}@${HOSTNAME}: ${PWD/$HOME/~}\007"

        ;;
*)
;;
esac
}

PROMPT_COMMAND=prompt_command

I am by no means an expert Bash scripter however, once I started looking at the code I was able to roughly figure out how this worked. Obviously this code be improved upon but this serves my purpose for now.

Many thanks

SWFSHAPE.SETLEFTFILL(3) 						 1						   SWFSHAPE.SETLEFTFILL(3)

SWFShape::setLeftFill - Sets left rasterizing color

SYNOPSIS
void SWFShape::setLeftFill (SWFGradient $fill) DESCRIPTION
void setLeftFill (int $red, int $green, int $blue, [int $a]) Warning This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk. What this nonsense is about is, every edge segment borders at most two fills. When rasterizing the object, it's pretty handy to know what those fills are ahead of time, so the swf format requires these to be specified. swfshape.setleftfill(3) sets the fill on the left side of the edge- that is, on the interior if you're defining the outline of the shape in a counter-clockwise fashion. The fill object is an SWFFill object returned from one of the addFill functions above. This seems to be reversed when you're defining a shape in a morph, though. If your browser crashes, just try setting the fill on the other side. Shortcut for $swfshape->setleftfill($s->addfill($r, $g, $b [, $a]));. RETURN VALUES
No value is returned. SEE ALSO
