What would you like to do?
A shell function to wrap tmux and make the basic commands a bit easier
#!/bin/bash

echo "$@"|tr "[:upper:]" "[:lower:]"

__menu() {
local result=""
PS3=$1

select opt in "$@" "Cancel"; do

# tmux wrapper
# tm session-name [window-name]
# Names can be partial from the beginning and first match will connect.
# If no match is found a new session will be created.
# If there's a second argument, it will be used to attach directly to a
# window in the session, or to name the first window in a new session.
#
# Update 2019-12-12
# Case insensitive session/window matching
# Allow numeric index for window (by index)
# Create new named window if second argument passed but no existing match
# Replace a bunch of sed and awk crud with -F params
# Add select menus when running without arguments
