This is taken care of in my .zshrc file with something like this pseudo code: case ${HOST} in (host1) PS1=<substitute your favorite prompt here> ;; (host2) PS1=<different colored prompt here> ;; esac I don't want to take the focus of this discussion off of zsh, but if you're using OS X and Terminal, you can set up a Terminal window to have the characteristics that you like (i.e. color of background), then save it as a .term file which you launch only when you want to ssh to a particular host. You can even set it so that just by launching a particular .term file, the ssh command will be carried out for you.

One remaining thing I want to accomplish is to set colors specifically for when I'm logged in as root (something subtle like a BRIGHT RED BACKGROUND and a flashing prompt saying YOU ARE ROOT!) However, I am starting to use 'sudo' instead of logging in as root, so that's probably a moot point now. Thanks for the pointers on the .term files, that's a good solution for the time being.

I have this on my /etc/zshenv: if [[ $USERNAME == root ]]; then export PS1=$'[%n@%m] %{\e[0;35m%}[%~] %{\e[0m%}%# ' else export PS1=$'[%n@%m] %{\e[0;32m%}[%~] %{\e[0m%}%# ' fi But it only sets the foreground color. You'll need to put another escape sequence to change the background too. regards, -- David Gómez Jabber ID: davidge@jabber.org ^ permalink raw reply [flat|nested] 11+ messages in thread

Depends on what the program is, but probably not. From the shell you can set the attributes of the text that is displayed (which is what MMJ is getting at in his reply) but not the color of the entire terminal. > I'm often logged into to 3 different computers (ssh), and it would be > handy to be able to quickly look for the color of one to know that it > was the one where I was connected to X [I wrote everything that follows while thinking "connected to X" meant "connected using an X11 terminal emulator", but now I think it means "to the host named X" so this may all be irrelevant. Having written it down, though, I'm going to send it anyway.] This is really an X11 question, and it depends on how you run your terminal emulators, but I'll do my best to turn it into a zsh question anyway. Let's assume xterm for discussion. If you run xterm locally and invoke the remote login from xterm, then you have to do something like this: ---- 8< ---- typeset -A xterm_colors xterm_colors=( host1 red host2 blue host3 green ) function xterm { setopt localoptions extendedglob noksharrays nokshglob # Fast crude command line parsing here, could be better if [[ " $*" = [[:space:]]-(fg|foreground) ]] then command xterm "$@" else local rshell='(ssh|rlogin|telnet)' local userpat='(|*@|-l[[:space:]][^[:space:]]#[[:space:]])' local remotepat="* -e ${rshell} ${userpat}(#b)([^[:space:]@]#)*" local color=white if [[ " $*" = ${~remotepat} && -n "${xterm_colors[${match[1]}]}" ]] then color=${xterm_colors[${match[1]}]} fi command xterm -fg $color "$@" fi } ---- 8< ---- However, if you instead run "xon host xterm ..." or the equivalent, then you can just put an appropriate X resource file, e.g. one named XTerm, in your home directory on the remote machine, and set the foreground color in that file. (Unless you have the same NFS-mounted home directory everywhere, in which case you're back to the first plan.) ^ permalink raw reply [flat|nested] 11+ messages in thread

But if you find that, you might be interested in my solution, which is to hash the hostname and generate a color from the result. I get a probably-different background color every time I connect to a new host. My code is on http://zshwiki.org/WishList and repeated here: # tint the terminal for each host bgcolor=`hostname | md5sum | /usr/local/bin/python -c "c1=raw_input(); col=[int(c1[x:x+2],16) for x in 0,2,4]; print '#%02x%02x%02x'%tuple([40*x/max(col) for x in col])"` print "\x1b]49;$bgcolor\x07" ^ permalink raw reply [flat|nested] 11+ messages in thread
