S6-EXPR(1)

✨ NAME ✨

hey bestie, welcome to the S6-EXPR(1) page from the General Commands Manual 💖. s6-expr evaluates an expression and writes the result to stdout — that's literally the whole job, and it ate ✨.

🎀 SYNOPSIS 🎀

okay so the vibe is:

s6-expr expression...

🦋 DESCRIPTION 🦋

so s6-expr acts as the generic expr[1] utility, except that the : operator (pattern matching) is not supported — nope, not even a little, bestie 🙈.

it accepts an arbitrary number of arguments. arbitrary means "however many you want to give it", fr fr 💅.

🔥 EXIT STATUS 🔥

• 111 — Temporary error. temporary error, so like, try-again vibes.
• 100 — Permanent error, such as a misuse. oof, permanent.
• 127 — Unable to execute program - not found. can't find it 😭
• 126 — Unable to execute program - other reason. other trouble, not the not-found kind.
