✨ TAC(1) — the General Commands Manual glow-up ✨

okay bestie, pull up a chair because tac is about to become your new fave 🫶 it lives in the General Commands Manual section, and tbh it's giving "reverse uno card for your files" — no cap.

🌸 NAME 🌸

tac — write each file to standard output, last line first. 💅

🦋 SYNOPSIS 🦋

tac [OPTION]... [FILE]...

💖 DESCRIPTION 💖

Write each file to standard output, last line first. That's it, that's the whole vibe. It's cat but walking backwards down the runway, main character energy, flipping the whole script. iconic. ✨

🎀 OPTIONS 🎀

  • -b, --before — attach the separator before instead of after. little pre-game separator moment 🎀
  • -r, --regex — interpret the sequence as a regular expression. fancy mode activated, she's doing pattern math now 🔥
  • -s, --separator <STRING> — use STRING as the separator instead of newline. you pick the divider, she respects it 💜
  • -h, --help — print help. your bestie explaining herself 📖
  • -V, --version — print version. the "who am i" moment 👑
