What order are the limits files in the limits.d directory read in?

Solution Unverified - Updated -

Environment

  • Red Hat Enterprise Linux 5,6

Issue

  • What order are the limits files in the limits.d directory read in?
  • What is the order in reading system limit entries?

Resolution

After reading /etc/security/limits.conf, individual files from the /etc/security/limits.d/ directory are read. The files are parsed one after another in the order of "C" locale. So the order will be special characters, numbers in ascending order, uppercase letters and lowercase letters in alphabetical order. If two files have same entry, then the entry read last will be taken in effect. Only files with *.conf extension will be read from this directory.
