🎀 RCTL.CONF(5) 🎀

okay so this is the manual page for rctl.conf — it lives in File Formats Manual, and honestly? underrated.

✨ NAME ✨

rctl.conf — the resource limits database defaults, bestie. that's the whole vibe.

💖 DESCRIPTION 💖

so like, the /etc/rctl.conf file gets read in when the system goes into multi-user mode, and its whole job is to set the default contents of the RCTL database. main character energy, truly. 👑

and the way /etc/rctl.conf is formatted? it's literally in the format of the rctl(8) command, i.e.

subject:subject-id:resource:action=amount/per

comments are denoted by a # at the beginning of a line — yes bestie, that's the move. 🫶 but also!! comments can exist at the end of a line too, as seen in the EXAMPLES section below. iykyk.

🦋 FILES 🦋

  • /etc/rctl.conf — initial settings for rctl(8). that's it, that's the file. 💅

🌸 EXAMPLES 🌸

so say you wanna limit the number of processes for users in login class "testing" — you'd use a rule like this:

# Resource limits for the "testing" class.
loginclass:testing:maxproc:deny=100/user # At most 100 processes per user

see how the comment sits right there at the end of the line? iconic. no cap. 🔥
