tx

03.02.2023

I have recently been trying to do a proper setup of tmux and as a part of it i made this little shell function to make re-attaching sessions a bit easier. It will give fzf prompt with available sessions if called without a session name. On the other hand when called with a session name it will check if it exists and attach or create based on the result.

tx() {
  if [ -z ${1+x} ]; then
    session=$(tmux list-sessions | fzf | awk '{print $1}' | sed 's/:$//' )
    tmux a -t $session
  else
    if tmux list-sessions | grep $1 2>&1 > /dev/null; then
      tmux a -t $1
    else
      tmux new -s $1
    fi
  fi
}

_tx() {
  sessions=$(tmux list-sessions 2>/dev/null)
  if [[ -z "$1" ]]; then
     echo $sessions | awk '{split($0,a,":"); print a[1]}'
  else
    echo $sessions | awk '{split($0,a,":"); print a[1]}' | grep --color=never $1
  fi
}
