- GNU mcron --- README -*-text-*-
- Copyright (C) 2003, 2005, 2006, 2012, 2014 Dale Mellor
- Copying and distribution of this file, with or without modification,
- are permitted in any medium without royalty provided the copyright
- notice and this notice are preserved.
- This is version 1.0.8 of the GNU mcron program. It is designed and written by
- Dale Mellor, and replaces and hugely enhances Vixie cron. It is functionally
- complete, production quality code (did you expect less?), but has not received
- much testing yet. It has only been built on a GNU/Linux system, and will most
- likely fail on others (but you never know...).
- ----------------------------------------------------------------------
- IMPORTANT NOTICES
- Do not (yet) install this software on a machine which relies for its
- functioning on its current set of crontabs.
- For use as a replacement cron daemon on a system, the package must be installed
- by root.
- Before installing this package for the first time, it is necessary to terminate
- any running cron daemons on your system. If your old cron is not Vixie or
- accurately Vixie compatible (files in /var/cron/tabs*, /var/cron/allow,
- /var/cron/deny, /etc/crontab, /var/run/cron.pid) then you will need to clear out
- all old crontabs and make new ones afresh - or else look very carefully at the
- options you pass to the package configure script, as follows.
- It is often the case that GNU/Linux distributions and other Unices hacked the
- cron daemon to use different directories to those above. You can use configure
- options --spool-dir, --socket-file, --allow-file, --deny-file, --pid-file and
- --tmp-dir to make mcron behave similarly. Note that, with the exception of
- tmp-dir, none of these files or directories should be accessible by ordinary
- (non-root) users.
- If your old cron is Vixie, or very similar, mcron should fall right into place
- where your old cron was (the binaries cron and crontab will be replaced, but if
- your existing system has a binary called crond, you should make this a link
- to mcron), and you should be able to continue to use your existing crontabs
- without noticing any changes.
- If you don't want to clobber your existing cron executables, you can specify
- the --program-prefix option to configure with a prefix ending in a
- non-alphabetic character, for example "m.", and then run the programs as
- m.mcron, m.cron (or m.crond) and m.crontab.
- ----------------------------------------------------------------------
- See the file INSTALL for generic building and installation instructions.
- After compilation, read the info file for full instructions for use (typing
- 'info -f doc/mcron.info' at the command line should suffice). Notes for end
- users, sysadmins, and developers who wish to incorporate mcron into their own
- programs are included here.
- Features which might be implemented sometime sooner or later are noted in the
- TODO file.
- Please send all other bug reports to bug-mcron@gnu.org. Other mailing lists you
- could subscribe to are help-mcron@gnu.org (for help and advice from the
- community, including the author) and info-mcron@gnu.org (for news as it
- happens).
- Mcron is free software. See the file COPYING for copying conditions.
- The mcron development home page is at http://www.gnu.org/software/mcron, and it
- can be obtained from ftp://ftp.gnu.org/pub/gnu/mcron.
