What the other said, is correct, so you already know what is happening here.
However, here is just another example for you:
# ~/.bash_profile: executed by bash(1) for login shells.
[...snipped...]
set_prompt ()
{
local SAVE_CRS=`tput sc 2> /dev/null`
local RESET_CRS=`tput rc 2> /dev/null`
local CLOCKPOS=`tput cup 0 $(($HZ-10)) 2> /dev/null`
local FOREG=`tput setaf 6 2> /dev/null` #4
local ALT_FOREG=`tput setaf 3 2> /dev/null` #4
local BACKG=`tput setab 0 2> /dev/null` #6
local NORMAL=`tput sgr0 2> /dev/null`
local BOLD=`tput bold 2> /dev/null`
PS1="\[${NORMAL}${SAVE_CRS}${CLOCKPOS}${FOREG}${BACKG}${BOLD} \@ [EMAIL
PROTECTED]:\w\$ "
}
set_prompt
This is will display a yellow username, (in normal colors) "@" + hostname, ":"
+ path, "$"
and a cyan clock in the upper right corner, 10 columns from the line end.
The clock will only be updated when you enter a new command, though (or
press return). The clock is annyoing when scrolling up or cutting and
pasting. However, it is just a demonstration how to do cursor movements.
Note that you don't need to enter _any_ escape commands, because I use tput
to get them. See "man 5 terminfo" for a list of terminal capabilities.
bye,
Marcus
