SEQ(1plan9)

💖 SEQ(1plan9) 💖

okay bestie, welcome to section 1 of the Plan 9 manual, where we talk about seq — the little command that goes brrr and prints you a whole list of numbers. she's simple, she's iconic, she's giving calculator-but-make-it-fancy. ✨

🎀 NAME 🎀

seq — print sequences of numbers 💅

---

🌸 SYNOPSIS 🌸

seq [ -w ] [ -fformat ] [ first [ incr ] ] last

---

🦋 DESCRIPTION 🦋

seq prints a sequence of numbers, one per line, starting from first (and if you don't give her a first, she defaults to 1) and going up to as near last as possible, stepping by incr (default 1 if you don't say otherwise). no cap, that's the whole vibe.

the loop is literally this, bestie:

for(val = min; val <= max; val += incr) print val;

the numbers are interpreted as floating point. yes, floats. she contains multitudes. 🌈

normally, integer values get printed as plain decimal integers. and then there are the options:

---

✨ OPTIONS ✨

• -fformat — use the print(3)-style format print for printing each (floating point) number. the default is

not me noticing the manpage literally says "The default is" and then just… stops 💀 the page leaves it hanging, so i'm leaving it hanging too. no invented facts on my watch.

• -w — equalize the widths of all the numbers by padding with leading zeros as necessary. heads up though: it's not effective with option -f, and it's also not effective with numbers in exponential notation. so pick your fighter. 🥊

---

👑 EXAMPLES 👑

1. seq 0 .05 .1 — print 0 0.05 0.1 (each on its own separate line). clean, minimal, ate. 🍓
2. seq -w 0 .05 .1 — print 0.00 0.05 0.10. same numbers, now with matching widths, because symmetry is self care. 🎀

🌈 SOURCE 🌈

/src/cmd/seq.c

go read the source if you want the tea straight from the kettle 🫖

💀 BUGS 💀

option -w always surveys every value in advance. so seq -w 1000000000 is a genuinely painful way to try and get an 'infinite' sequence. like, it will absolutely make you wait. do not do this to your terminal, she doesn't deserve it. 😭

and that's the whole page, bestie!! this was section 1 of the Plan 9 manual, and the footer was just SEQ(1plan9) — no extra version string, no date, just the name looking cute. slay, mwah, go print some numbers 💖✨🧚
