Change Title of Terminal Window to Verbose Info useful at Login

echo -ne "\033]0;`id -un`:`id -gn`@`hostname||uname -n|sed 1q` `who -m|sed -e "s%^.* \(pts/[0-9]*\).*(\(.*\))%[\1] (\2)%g"` [`uptime|sed -e "s/.*: \([^,]*\).*/\1/" -e "s/ //g"` / `ps aux|wc -l`]\007"
I usually have 5 or more ssh connections to various servers, and putting this command in my .bash_profile file makes my putty window or x terminal window title change to this easily recognizable and descriptive text. Includes the username, group, server hostname, where I am connecting from (for SSH tunneling), which device pts, current server load, and how many processes are running. You can also use this for your PROMPT_COMMAND variable, which updates the window title to the current values each time you exec a command. I prefix running this in my .bash_profile with [[ ! -z "$SSH_TTY" ]] && which makes sure it only does this when connecting via SSH with a TTY. Here's some rougher examples from http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html # If set, the value is executed as a command prior to issuing each primary prompt. #H=$((hostname || uname -n) 2>/dev/null | sed 1q);W=$(whoami) #export PROMPT_COMMAND='echo -ne "\033]0;${W}@${H}:${PWD/#$HOME/~} ${SSH_TTY/\/dev\//} [`uptime|sed -e "s/.*: \([^,]*\).*/\1/" -e "s/ //g"`]\007"' #PROMPT_COMMAND='echo -ne "\033]0;`id -un`:`id -gn`@`hostname||uname -n 2>/dev/null|sed 1q` `command who -m|sed -e "s%^.* \(pts/[0-9]*\).*(\(.*\))%[\1] (\2)%g"` [`uptime|sed -e "s/.*: \([^,]*\).*/\1/" -e "s/ //g"` / `command ps aux|wc -l`]\007"' #[[ -z "$SSH_TTY" ]] || export PROMPT_COMMAND #[[ -z "$SSH_TTY" ]] && [[ -f /dev/stdout ]] && SSH_TTY=/dev/stdout And here's a simple function example for setting the title: function set_window_title(){ echo -e "\033]0; ${1:-$USER@$HOST - $SHLVL} \007"; }

  • Found another way, more compatible. Tested with xterm, aterm, gnome-terminal and rxvt (where it sets the window title) and guake (where it doesn't - after all, guake does not show the window title).

  • If you are using an xterm emulation capable terminal emulator, such as PuTTY or xterm on Linux desktop, this command will replace the title of that terminal window. I know it is not nice to have seventeen terminals on your desktop with title PuTTY, you can not tell which one is connected to which server and doing what. Even though the string between the quotes is typed as literals, it needs a little more finesse to make it work. Here is how it is done key-by-key: echo "( ctrl-v then ctrl-[ )0;Enter_Title_String_Here( ctrl-v then ctrl-g )"( enter ) ctrl-v : means hold down ctrl key and hit v at the same time like you are pasting in windoze ; also please don't type the parentheses, i.e., ( and )

  • when using Gnome or KDE, you will have a hard time getting a screenshot of something like a login screen, or any other screen that occurs before the desktop environment is up and monitoring the printscreen key. (this probably applies for other DEs as well, but I haven't used them) What this command is meant to do is take a screenshot of an X window using a command you can run from your virtual terminals (actual text terminals, not just an emulator) To do this: Press CTRL+ALT+F1 to go to a virtual (text) terminal once your login window comes up Login to the virtual terminal and enter the command (you'll have to type it in) You should now have a file called screenshot.png in your home directory with your screenshot in it. For those of you who are new to the virtual terminal thing, you can use CTRL+ALT+F7 to get back to your regular GUI From http://www.gnome.org
