2 tmux-aliases.sh

# Some tmux-related shell aliases

# Attaches tmux to the last session; creates a new session if none exists.
alias t='tmux attach || tmux new-session'

# Attaches tmux to a session (example: ta portal)
alias ta='tmux attach -t'

# Creates a new session
alias tn='tmux new-session'

# Lists all ongoing sessions
alias tl='tmux list-sessions'

3 tmux-session-setup.sh

#!/bin/bash

SESSION='my_session'

# Example of tmux session setup script. This particular example starts several
# rails servers on a development machine. The session we create is named "my_session".
 
# Tests to see if the session already exists. If it does, just skip everything and reattach.
if [ "$(tmux list-sessions 2> /dev/null | grep -o $SESSION)" != "$SESSION" ]; then
 
  tmux new-session -d -s $SESSION

  # NOTE: We have to call bash (or $SHELL) after every command, or else the window will quit.
  #       This is not necessary if you don't run any commands.

  tmux new-window -t $SESSION:1 -n '(Q)scheduler' "cd ~/Code/queue_service; VERBOSE=1 bundle exec rake resque:scheduler; $SHELL"
  tmux new-window -t $SESSION:2 -n '(Q)worker' "cd ~/Code/queue_service; QUEUE=* VERBOSE=1 bundle exec rake resque:work; $SHELL"
  tmux new-window -t $SESSION:3 -n '(D)keywords' "cd ~/Code/data-collection; bundle exec ruby run_keywords.rb; $SHELL"
  tmux new-window -t $SESSION:4 -n '(D)follow' "cd ~/Code/data-collection; bundle exec ruby run_follow.rb; $SHELL"
  tmux new-window -t $SESSION:5 -n '(R)app' "cd ~/Code/app; bundle exec rails server -p 3000; $SHELL"
 
  # Gets rid of window 0, which is not accessible right away (hence sleep 1)
  sleep 1
  tmux unlink-window -k -t $SESSION:0
 
else
  tmux attach -t $SESSION
fi

Attaches tmux to the last session; creates a new session with a panel split into left and right

alias t='tmux attach || tmux new-session\; split-window -h'

By default tmux ls is alias of tmux list-sessions
