PCP-IPCS(1)

💖 pcp-ipcs — the manual page, but make it make sense 💖

okay bestie, so this is pcp-ipcs from the General Commands Manual section of the Performance Co-Pilot crew, and it's genuinely one of the most lowkey useful little tools in the PCP universe. it's giving "tell me everything about IPC" energy. let's get into it 🫶

✨ NAME ✨

pcp-ipcs — provide information on IPC facilities

like, that's it, that's the whole job. it spills the tea on your inter-process communication facilities 🍓

---

🌸 SYNOPSIS 🌸

pcp [pcp options] ipcs [-luV?] [output-format]

yes she's invoked through pcp — she's a subcommand, a little sister to the big pcp(1) moment. pcp options first, then ipcs, then her own flags, then the optional output-format if you're feeling fancy 💅

---

🦋 DESCRIPTION 🦋

pcp-ipcs provides information on the inter-process communication facilities for which the calling process has read access.

that last part is doing a lot of work, so let's repeat it for the people in the back: she only shows you what your process is allowed to read. no read access, no info. that's the vibe check and she's not bending the rules 🙈

---

👑 OPTIONS 👑

so when you invoke her via the pcp(1) command, the -h/--host, -a/--archive, -O/--origin, -Z/--timezone and several other pcp options become indirectly available. they're not hers, they're borrowed from the main character. for the complete description of those, go read PCPIntro(1) — she said so herself.

the additional command line options available for pcp-ipcs are:

• -V, --version — display version information and exit. bye bestie, you got your answer 👋
• -?, --help — display the usage message and exit. when you're lost, she's got you 🥺

🌈 Output formats 🌈

• -l, --limits — show resource limits. the caps, the ceilings, the "you shall not pass" numbers 🚧
• -u, --summary — show status summary. the quick lil recap, no scrolling required ⭐

---

💜 PCP ENVIRONMENT 💜

environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. that's the naming convention, she's committed to it ✨

on each installation, the file /etc/pcp.conf contains the local values for these variables. and listen — the $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf(5). so if you wanna point her somewhere else, $PCP_CONF is your girl 💖

for environment variables affecting PCP tools, see pmGetOptions(3). go read it. i'm serious. iykyk 📖

and that's a wrap bestie — this was Performance Co-Pilot, PCP, manual page PCP-IPCS(1), and she slayed. mwah 🫶💖
