HOWTO: populate your term’s title automatically

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic.

g33k When you’re running a ton of termial windows or tabs, it helps to have the title of the box name, along with some environment values, easily available to keep you orientated. Here’s a quick script I created to do this automatically when called via your .profile file in your home directory.

#!/bin/bash
HOST_NAME=`hostname -f`
if [ `id -u` = 0 ]; then
OPT="`uname` (`uname -a | cut -f12 -d' ' -`) - ROOT USER"
else
OPT="`uname` (`uname -a | cut -f12 -d' ' -`)"
fi
REPLACE="${HOST_NAME} - ${OPT}"
echo -n -e "\033]0; $REPLACE \007 "
echo "${REPLACE}"
exit 0

When I run this script in my term here at work, the title or tab becomes:

nldg-8 (Linux / x86_64)

Drop this into a bin directory your user can hit – I always put on in my home directory and append ~/bin to my PATH in my .profile. For Solaris fans/users, it needs to be done a bit differently:

#!/usr/local/bin/bash
HOST_NAME=`uname -a | cut -f2 -d' ' -`
OPT="(`uname -a | cut -f1 -d' ' -` / `uname -a | cut -f6 -d' '`)"
REPLACE="${HOST_NAME} - ${OPT}"
echo -n -e "\033]0; $REPLACE \007 "
echo "${REPLACE}"
exit 0

Seems to work.
Have you considered putting this into a shell function in your .bashrc,
titled something like, “set_title”.
Then. If you were to create a “_cd” function that did “cd” $@ first thing, then executed your set_title with a parameter, you could even figure out how to get your current working directory in your title bar.
If you wanted to, that is.
I usually combine the title setting with the setting of my PS1 variable in my _cd().
Hope this finds you well,
cas

Nice, I never thought of that, the way I do it is have my PS1 contain this info:
[11:04:49] [fak3r@chavez /home/faj3r/build/bin]$
This has all the info I need, plus it truncates the path if it get’s too long, keeping my prompt at least a big consistant. Here’s my .bashrc:
bash_prompt_command() { # How many characters of the $PWD should be kept local pwdmaxlen=25 # Indicate that there has been dir truncation local trunc_symbol=".." local dir=${PWD##*/} pwdmaxlen=$(( ( pwdmaxlen} local pwdoffset=$(( ${#NEW_PWD} - pwdmaxlen )) if [ ${pwdoffset} -gt "0" ] then NEW_PWD=${NEW_PWD:$pwdoffset:$pwdmaxlen} NEW_PWD=${trunc_symbol}/${NEW_PWD#*/} fi } # bash_prompt() { local NONE='\[\033[0m\]' # unsets color to term's fg color
# regular colors local K='\[\033[0;30m\]' # black local R='\[\033[0;31m\]' # red local G='\[\033[0;32m\]' # green local Y='\[\033[0;33m\]' # yellow local B='\[\033[0;34m\]' # blue local M='\[\033[0;35m\]' # magenta local C='\[\033[0;36m\]' # cyan local W='\[\033[0;37m\]' # white
# empahsized (bolded) colors local EMK='\[\033[1;30m\]' local EMR='\[\033[1;31m\]' local EMG='\[\033[1;32m\]' local EMY='\[\033[1;33m\]' local EMB='\[\033[1;34m\]' local EMM='\[\033[1;35m\]' local EMC='\[\033[1;36m\]' local EMW='\[\033[1;37m\]'
# background colors local BGK='\[\033[40m\]' local BGR='\[\033[41m\]' local BGG='\[\033[42m\]' local BGY='\[\033[43m\]' local BGB='\[\033[44m\]' local BGM='\[\033[45m\]' local BGC='\[\033[46m\]' local BGW='\[\033[47m\]'
local UC=$C # user's color [ $UID -eq "0" ] && UC=$R # root's color
PS1="${W}[\t${W}] ${Y}[${R}\u${R}@${R}\h ${EMB}\${NEW_PWD}${Y}]${W}\\$ ${NONE}" } # PROMPT_COMMAND=bash_prompt_command bash_prompt unset bash_prompt
Appreciate the advice!
