This is version 0.99.1 of the mcron program, designed and written by Dale
|
|
Mellor, which replaces and hugely enhances Vixie cron. It is functionally
|
|
complete, production quality code (did you expect less?), but has not received
|
|
much testing yet and contains known bugs. It has only been built on a GNU/Linux
|
|
system, and will most likely fail on others (but you never know...).
|
|
|
|
Mcron is supposed to be 100% Vixie compatible. However, in the current release
|
|
this is broken, and by default only 50% compatibility is installed.

|
IMPORTANT NOTICES
|
|
|
|
Read the BUGS file.
|
|
|
|
By default, the cron and crontab programs are not installed, and mcron will
|
|
happiliy coexist alongside any existing cron programs you have on your
|
|
system. The Vixie-style programs can be installed by specifying --enable-vixie
|
|
to the configure command, in which case you must take heed of the following
|
|
notes.
|
|
|
|
|
|
Do not (yet) install this software on a machine which relies for its
|
|
functioning on its current set of crontabs.
|
|
|
|
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
|
|
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.
|
|
|
|
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), and you should be able to continue to use your existing crontabs
|
|
without noticing any changes. Bear in mind that if you use /etc/crontab,
|
|
then changes to this file will *not* take immediate effect (this is the 1%
|
|
incompatibility between mcron and Vixie cron); you may want to add a comment
|
|
to this file with a note to this effect. Alternatively, use the new mcron
|
|
program, it's better!
|
|
|
|
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 and m.crontab.

|
After installation, read the info file for full instructions for use (type
|
|
`info mcron' at the command line).

|
Known bugs are noted in the BUGS file, and features which might be implemented
|
|
sometime sooner or later are noted in the TODO file.
