MARIADB-WAITPID(1)

💫 MARIADB-WAITPID 💫

okay bestie, welcome to mariadb-waitpid(1), straight out of the MariaDB Database System manual 💖 she's a tiny little tool but she does exactly one job and she does it flawlessly, which honestly is main character energy.

---

🌸 NAME 🌸

mariadb-waitpid — kill a process and wait for its termination 🫶

(and yes, the plot twist: mariadb-waitpid is now a symlink to mariadb-waitpid — iconic, no notes, that's literally what it says ✨)

---

🎀 SYNOPSIS 🎀

mariadb-waitpid [options] pid wait_time

---

🦋 DESCRIPTION 🦋

so here's the vibe: mariadb-waitpid signals a process to terminate, and then it waits for that process to actually exit. patient queen behavior 💅

it does this using the kill() system call and Unix signals — so like, this is a Unix and Unix-like systems situation only, no cap. 🌈

you invoke her like this:

shell> mariadb-waitpid [options] pid wait_time

mariadb-waitpid sends signal 0 to the process identified by pid, then waits up to wait_time seconds for that process to terminate. and listen — pid and wait_time must be positive integers. that's non-negotiable, she's not doing decimals. 😤

here's the scoring system, bestie:

• if the process termination happens within the wait time, or if the process doesn't exist at all → she returns 0 ✨
• otherwise → she returns 1 💀

and one little technical note iykyk: if the kill() system call cannot handle signal 0, then mariadb-waitpid() uses signal 1 instead. she's got a backup plan, obviously. 🔥

mariadb-waitpid supports the following options:

• --help, -?, -I — display a help message and exit. the "wait what does this do again" button 🙈
• --verbose, -v — verbose mode. displays a warning if signal 0 could not be used and signal 1 is used instead. she'll literally tell you when she had to switch it up 👑
• --version, -V — display version information and exit. the "who even are you" button 💖
