Dude, it's UNIX... you can do whatever you want. Here's some functions that should work in ksh or bash. Notice that if you put this in your .bashrc or .kshrc file using
vi, you would create the "^[" by pressing control-V and then the Escape key. ^G is created by control-V and then control-G. All other characters are verbatim, and are the property of their owners.
wt changes the window title on the fly. Use it like: wt anything you want
it changes the window title and the icon title. Usage: it anything you want
defwt is my default window title, it shows you how to put a shell function in the window title.
cls is clear screen. Xterms are like vt100's, so it will work.
These functions work for many other vt100 emulators, I have found.
This is for Sun's echo command, which takes a \c to tell you not to send a carriage return at the end. For Linux you have to use its version. I think echo is deprecated and you want to use printf, but I'm not in front of Linux right now to check if it has printf also.
Code:
# X title stuff
wt ()
{
echo "^[]2;${@}^G\c"
}
it ()
{
echo "^[]0;${@}^G\c"
}
defwt ()
{
echo "^[]2;$(whoami) @ $(hostname)^G"
}
cls ()
{
# works only for vt100's and the like
echo "^[[;H^[[2J"
}
In Real Life, I have yet another function that dynamically modifies my window title to show me my current directory, but that will cost you extra.
Oh, ok... this works on bash but my older version worked on ksh. You would have to figure out how to get it to work with ksh. Better to switch to bash, IMHO.
Code:
PROMPT_COMMAND=pc
titlebar="$myhostname ::: $myname "
tprompt="[$myname@$myhostname]"
if [ "$TERM" != "void" -a "$TERM" != "dumb" ] ; then
bold=`tput bold`
normal=`tput rmso`
PROMPT_COMMAND=pc
#PS1="\!\\[$bold\\]\`promptlen\`\\[$normal\\]\\$ "
fi
function pc
{
pc_wd=`pwd`
if [ \( "$TERM" = "vt100" \) -o \( "$TERM" = "xterm" \) ] ; then
wt "$titlebar << `pwd` >>" > `tty`
fi
# go to a 2-line prompt if >38 chars in path...
case "$pc_wd" in
/)
pc_path="/" ; pc_suffix="\\$ "
;;
$HOME)
pc_path="~" ; pc_suffix="\\$ "
;;
??????????????????????????????????????*)
pc_path=$pc_wd ; pc_suffix="\n\\$ "
;;
*)
pc_path=$pc_wd ; pc_suffix="\\$ "
;;
esac
PS1="\!\\[$bold\\]${tprompt}${pc_path}\\[$normal\\]${pc_suffix}"
return
}
...bold and normal do not work under Linux here. This is from my Sun, sorry. I have a version that works on Linux and Solaris but it's at work and I'm not.
