This is a version of 'cron' that is known to run on BSD 4.[23] systems. It
|
| 28 |
is functionally based on the SysV cron, which means that each user can have
|
| 29 |
their own crontab file (all crontab files are stored in a read-protected
|
| 30 |
directory, usually /var/cron/tabs). No direct support is provided for
|
| 31 |
'at'; you can continue to run 'atrun' from the crontab as you have been
|
| 32 |
doing. If you don't have atrun (i.e., System V) you are in trouble.
|
| 33 |
|
| 34 |
A messages is logged each time a command is executed; also, the files
|
| 35 |
"allow" and "deny" in /var/cron can be used to control access to the
|
| 36 |
"crontab" command (which installs crontabs). It hasn't been tested on
|
| 37 |
SysV, although some effort has gone into making the port an easy one.
|
| 38 |

This is more or less the copyright that USENET contributed software usually
|
| 40 |
has. Since ATT couldn't use this version if they had to freely distribute
|
| 41 |
source, and since I'd love to see them use it, I'll offer some rediculously
|
| 42 |
low license fee just to have them take it. In the unlikely event that they
|
| 43 |
do this, I will continue to support and distribute the pseudo-PD version, so
|
| 44 |
please, don't flame me for wanting my work to see a wider distribution.
|
| 45 |
|
| 46 |
To use this: Sorry, folks, there is no cutesy 'Configure' script. You'll
|
| 47 |
have to go edit a couple of files... So, here's the checklist:
|
| 48 |
|
| 49 |
Read all the FEATURES, INSTALL, and CONVERSION files
|
| 50 |
Edit config.h
|
| 51 |
Edit Makefile
|
| 52 |
(both of these files have instructions inside; note that
|
| 53 |
some things in config.h are definable in Makefile and are
|
| 54 |
therefore surrounded by #ifndef...#endif)
|
| 55 |
'make'
|
| 56 |
'su' and 'make install'
|
| 57 |
(you may have to install the man pages by hand)
|
| 58 |
kill your existing cron process
|
| 59 |
(actually you can run your existing cron if you want, but why?)
|
| 60 |
build new crontabs using /usr/lib/{crontab,crontab.local}
|
| 61 |
(either put them all in "root"'s crontab, or divide it up
|
| 62 |
and rip out all the 'su' commands, collapse the lengthy
|
| 63 |
lists into ranges with steps -- basically, this step is
|
| 64 |
as much work as you want to make it)
|
| 65 |
start up the new cron
|
| 66 |
(must be done as root)
|
| 67 |
watch it. test it with 'crontab -r' and watch the daemon track your
|
| 68 |
changes.
|
| 69 |
if you like it, change your /etc/{rc,rc.local} to use it instead of
|
| 70 |
the old one.
