ulimit

Get and set resource limits for user processes. It is a shell builtin hence not shell-agnostic. More information: https://www.gnu.org/software/bash/manual/bash.html#index-ulimit.

  • Get the properties of all the user limits:

ulimit -a

  • Get hard limit for the number of simultaneously opened files:

ulimit -H -n

  • Get soft limit for the number of simultaneously opened files:

ulimit -S -n

  • Set max per-user process limit:

ulimit -u 30

  • Display help (Bash only):

help ulimit
