commit 7e863cb9893b96f4ca6e0597572e3df218dd3830 Author: Juraj Lutter <[email protected]> AuthorDate: 2021-02-28 22:07:14 +0000 Commit: Juraj Lutter <[email protected]> CommitDate: 2021-05-23 13:35:51 +0000 newsyslog(8): Implement a new 'E' flag to not rotate empty log files Based on an idea from dvl's coworker, László DANIELISZ, implement a new flag, 'E', that prevents newsyslog(8) from rotating the empty log files. This 'E' flag ist mostly usable in conjunction with 'B' flag that instructs newsyslog(8) to not insert an informational message into the log file after rotation, keeping it still empty.
