As I had pointed out in my post about tmux<\/a> that now I am using tmux to configure and debug multiple servers inside a single window split into panes. Now I ran to another problem I always forgot which pane was meant for which service. Beyond 2 to 3 panes it was getting confusing to remember which pane is monitoring which service. So I remembered my previous post related to tput<\/a> which allows anybody to show a running clock inside a linux terminal. So I decided to provision a small shell script to fix this issue. Basically I wanted a way to label each pane so that I could effortlessly identify the purpose of the pane inside tmux. So here is the code:
\n
\n#!\/bin\/bash
\n#Display Service Name<\/p>\n

function die {
\n echo \"Dying on signal $1\"
\n exit 0
\n}<\/p>\n

function redraw {
\n local width length;
\n width=$(tput cols);
\n str=$1;
\n length=${#str}+10;
\n tput sc;
\n tput cup 0 $((width-length));
\n set_foreground=$(tput setaf 7)
\n set_background=$(tput setab 1)
\n echo -n $set_background$set_foreground
\n printf ' Service:%s ' $str
\n tput sgr0;
\n tput rc;
\n}<\/p>\n

trap 'die \"SIGINT\"' SIGINT
\ntrap 'die \"SIGQUIT\"' SIGQUIT<\/p>\n

trap redraw WINCH;<\/p>\n

while true; do
\n redraw $*;
\n sleep 1;
\ndone
\n<\/code><\/p>\n

This shell script takes a parameter and shows it on the top right column in a red background with white foreground. This script should be invoked in this way.
\n
\n.\/ShowTextInTerm.sh service-name &
\n<\/code><\/p>\n

Invoking this script in every tmux pane with relevant substitution for service-name is giving me this result:
\n\"Screen<\/a><\/p>\n

Please note that this script works well on my MacBook. I am yet to test it on a Linux terminal. <\/p>\n","protected":false},"excerpt":{"rendered":"
