Tmux sessionizer

May 5, 2025

I came across tmux-sessionizer today, and this has become handy in how I’m managing tmux sesisons.

For my workflow, I added an alias that’ll launch tmux-sessionizer. tmux-sessionizer

I’ve made some slight modifications to fit my dev setup.

#!/usr/bin/env bash

if [[ $# -eq 1 ]]; then
    selected=$1
else
    selected=$(find ~/Dev ~/Dev/personal ~/Dev/work ~/Dev/personal/projects ~/Dev/personal/opensource ~/Dev/personal/learning -mindepth 1 -maxdepth 1 -type d | fzf)
fi

if [[ -z $selected ]]; then
    exit 0
fi

selected_name=$(basename "$selected" | tr . _)
tmux_running=$(pgrep tmux)

if [[ -z $TMUX ]] && [[ -z $tmux_running ]]; then
    tmux new-session -s $selected_name -c $selected
    exit 0
fi

if ! tmux has-session -t=$selected_name 2> /dev/null; then
    tmux new-session -ds $selected_name -c $selected
fi

if [[ -n $TMUX ]]; then
  tmux switch-client -t $selected_name
else 
  tmux attach-session -t $selected_name
fi
