augenrules — a script that merges component audit rule files
augenrules [--check] [--load]
augenrules is a script that merges all component audit rules files, found in the audit rules directory, /etc/audit/rules.d, placing the merged file in /etc/audit/audit.rules. Component audit rule files, must end in .rules in order to be processed. All other files in /etc/audit/rules.d are ignored.
The files are concatenated in order, based on their natural sort (see -v option of ls(1)) and stripped of empty and comment (#) lines.
The last processed -D directive without an option, if present, is always emitted as the first line in the resultant file. Those with an option are replicated in place. The last processed -b directive, if present, is always emitted as the second line in the resultant file. The last processed -f directive, if present, is always emitted as the third line in the resultant file. The last processed -e directive, if present, is always emitted as the last line in the resultant file.
The generated file is only copied to /etc/audit/audit.rules, if it differs.
test if rules have changed and need updating without overwriting audit.rules.
load old or newly built rules into the kernel.
