SYD_SH(1)

📦 version 3.51.2, in nixos 26.05

💅 SYD_SH(1) — like, the syd-sh manual page, bestie 🎀

okay so welcome to syd-sh(1), the manual page for the cutest littlest confined shell you ever met ✨ (this is from the General Commands Manual, section 1, iykyk)

🌸 NAME 🌸

syd-sh — a Simple confined shell based on wordexp(3) 🐚💖

✨ SYNOPSIS ✨

syd-sh [-helsx] [--] [command_file [argument...]]

syd-sh [-helx] -c command_string [command_name [argument...]]

like, both forms, literally, exactly like that 🫶

🦋 DESCRIPTION 🦋

so syd-sh is a simple confined shell based on wordexp(3). periodt. 💅

every single command gets executed in its own confined environment — no cap, its own one. the confinement is done using Landlock, namespaces and seccomp 🔥 (yes, all three, the whole squad).

and the command timeout is 3 seconds. three. seconds. so don't be out here running your giant build in it, bestie 😭

👑 OPTIONS 👑

  • -h — displays help. that's it, that's the whole vibe 🎀
  • -c — reads commands from the given command_string operand. and like, no commands are read from standard input at all when you do this. none. zero. 🙈
  • -e — if you're not interactive, exits immediately if any untested command fails. like, no second chances, it's giving main character exit energy 💀
  • -l — ignored. literally ignored. it's just there for login shell compatibility, so like, don't worry about it ✨
  • -s — reads commands from the standard input. and if there are no operands and -c is not specified, the -s option is assumed. so it's the default, lowkey 👀
  • -x — writes each command to standard error (preceded by a "+" ) before it's executed. super useful for debugging, ngl 🔍
