💖 INTERVAL(1) 💖

okay bestie, so this is the manual page for interval — aka the numinterval girlies' moment to shine ✨ (user contributed perl documentation, we love to see it) 💅

🌸 NAME 🌸

numinterval — bestie, it shows you the numeric intervals between each line in a file. like, the gaps. the deltas. the what happened between these two numbers. iconic behavior honestly 🦋

🎀 SYNOPSIS 🎀

numinterval [-dhV] <FILE>

| numinterval [-dhV]    (Input on STDIN from pipeline.)

numinterval [-dhV]      (Input on STDIN.  Use Ctrl-D to stop.)

so basically three ways to pull up: hand it a <FILE>, pipe into it like the pipeline girlboss you are, or just run it bare and type at it — then hit Ctrl-D to stop. periodt 💅

✨ DESCRIPTION ✨

numinterval will calculate and display the numeric interval between one number and the next on an input stream. that's it, that's the whole job, and she does it flawlessly 😌

ngl this is highkey useful for showing quantities of increase or decrease of data when the numbers themselves aren't providing you with what you want. the numbers are giving nothing but numinterval is giving everything 💖

fr fr, the author literally wrote this program after wanting to see the rate of change in box office ticket sales for movies on imdb.com. ;-) — not me writing an entire unix utility because of movie ticket sales 😭 that's main character energy and I respect it deeply 🍓

👑 OPTIONS 👑

  • -h — Help: You're looking at it. 🫶 (yes bestie, the help is literally this page, very meta, we stan)
  • -V — Increase verbosity. she gets chatty 💬✨
  • -d — Debug mode. For developers 🧚 (only for the ones who write the code, not the ones who just vibe with it)
  • -q — Don't print any warnings. Quiet mode. 🤫 no thoughts, no warnings, just output 🌸
side note: the synopsis shows them all smushed together as -dhV, so yes you can absolutely stack them and have a little moment 💅
