logrotate:tldr:4471c

This command invokes the logrotate utility with the specified logrotate configuration file (${path-to-logrotate-conf}). The logrotate utility is responsible for managing and rotating log files to prevent them from becoming too large and consuming excessive disk space.

The "--state" option is used to specify the state file for logrotate. The state file keeps track of the last log files rotation timestamp. In this command, "/dev/null" is specified as the state file. "/dev/null" is a special device file in Unix-like systems that discards everything written to it without storing any data. By specifying "/dev/null" as the state file, logrotate will not retain any historical rotation information or timestamp records.

In summary, this command executes logrotate using a specified configuration file, and discards the state information (rotation timestamps) by directing it to "/dev/null".
