  • Rebuilding my terminal from a git clone
    Those four plugins are the ones that survived. Git for the aliases and the branch state, zsh-syntax-highlighting because a command turning red before I press Enter has caught more typos than I would like to admit, z to jump to a directory I visited last week by typing three letters of its name, and fzf-tab to hand tab-completion over to fzf, turning a wall of candidates into a fuzzy-searchable list. - Source: dev.to / 14 days ago
  • Every Claude Code session across all your projects, in one list — hit Enter to resume
    Claude-sessions instead lists every session from every project in one fzf picker, newest first. Hit Enter and the session opens in a new iTerm tab (or tmux window) running claude --resume in the right directory — while the picker stays open for the next one. - Source: dev.to / 2 months ago
  • My Mac crashed with 7 Claude Code sessions open. Never again: a cross-project session picker in one bash script
    Dependencies: fzf (brew install fzf) and python3 (ships with macOS). The tab-opening uses AppleScript for iTerm2 with a Terminal.app fallback; inside tmux it uses plain tmux new-window, which also makes that path Linux-friendly. - Source: dev.to / 2 months ago

    Please please stop spamming up arrow to find that command you ran. Instead you can make this so much simpler with fzf. - Source: dev.to / 4 months ago

  • Banana.dog back from the dead
    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
