IFNE(1)

💅 IFNE(1) — the moreutils girlies know 💅

okay bestie, welcome to ifne from the moreutils collection ✨ she's tiny, she's iconic, she's literally one job and she does it flawlessly 🎀

🌸 NAME 🌸

ifne — run command if the standard input is not empty 🫶

like. that's it. that's the whole girl. no cap.

✨ SYNOPSIS ✨

ifne [-n] command

🦋 DESCRIPTION 🦋

so here's the vibe: ifne runs the following command if and only if the standard input is not empty 💖

that's the entire plot. no plot twists. main character energy, minimal dialogue, ate. 👑

🎀 OPTIONS 🎀

• -n — reverse operation, bestie 🙈 run the command if the standard input is empty instead.

⚠️ heads up though: if the standard input is not empty, it gets passed through ifne in this case. so like, it still flows on through. don't forget that part, it's giving sneaky 💀

🌈 EXAMPLE 🌈

the classic, the blueprint, the one that makes you go "ohhhh that's why":

find . -name core | ifne mail -E 'set escape' -s "Core files found" root

like yes, find your core files, and only bother mailing root about it if there's actually something there 💌 no empty emails, no wasted drama, periodt.
