tmux vs. screen

I am an experienced GNU screen users for many years.  Recently, I learned to use tmux and found it is a great replacement of screen.

Tmux is originally developed in OpenBSD and was ported to many systems.

The configuration is easy with many configurable options. Here is my startup script of tmux.


# basic setup
export LD_LIBRARY_PATH=/home/me/lib

# session related setup


if [ "$ENV" = "" ]; then

$TMUX start-server
$TMUX new-session -d -s leo '/bin/bash'
$TMUX new-window -t leo:1 '/bin/bash'
$TMUX new-window -t leo:2 '/bin/bash'

case $ENV in
        $TMUX send-keys -t leo:0 'cd; ls -lrt' C-m
        $TMUX send-keys -t leo:0 "cd $ENGWEB; vim s.cgi" C-m
        $TMUX send-keys -t leo:1 "cd $LIBPERL; vim" C-m
        $TMUX send-keys -t leo:2 "cd $ENGWEB; ls -l" C-m
        $TMUX send-keys -t leo:0 "cd $HOME; ls -l" C-m
        $TMUX send-keys -t leo:1 "cd $HOME/bin; ls -l" C-m
        $TMUX send-keys -t leo:2 "cd $HOME/stats; ls -l" C-m


$TMUX select-window -t leo:0
$TMUX attach-session -t leo
