[comp.binaries.ibm.pc.d] SUMMARY: cron for MS-DOS

mpledger@cti1.UUCP (Mark Pledger) (01/08/91)

The following is a (very) short list of respondents to the following
request I made earlier:

>Does anyone know of a PD program similar to crontab that runs under
>MS-DOS?  If so could they please tell me where I can get it, either
>through ftp or a BBS.


------------------------------------------------------

1)  From Greg Presedo-Floyd

Both PCTOOLS in Washington state and Norton Utilites have "schedulers"
in their latest revs. They are not PD.  They are (I think) TSRs that
use pop up windows. I too (if I understand you) would like a more
"text file" based option.

------------------------------------------------------

2) From Phillip McReynolds

Try downloading Waffle ver 1.63 from Simtel:

PD1:<MSDOS.BBS>WAF163.ZIP

It has a scheduler which exits the bbs (more on that in a sec.) to
execute a list of programs at various times which you have placed in a
file called /waffle/system/schedule.  Very nice.  Unfortunately, you
have to run the bbs in order to get this feature to work.  BTW, I assume
you're using some sort of multi-tasking DOS extender like DESQview since
the cron program would take precedence and stop all current processing
when it executed its crontabs.  I use the DESQview + waffle arrangement
to do various things in the wee hours of the morning:  poll my neighbor
uucp sites, delete all *.bak files on the system, perform disk checks,
archive newsgroups, and so on.

-------------------------------------------------------

SUMMARY:

From the few responses I got, I gather there is no program which emulates
cron for an MS-DOS machine.  I am therefore going to write my own.  I
realize that since MS-DOS is inherently a single user, single task OS some
features of cron will not be able to be implemented.  My goals are to set
up a dayly, weekly, monthly, yearly, or specified event to happen based upon
a given crontab file.  I will probably use the autoexec.bat file to check
and run the crontab.  Since my machine is a 386, I also have use of the
timers which will allow me to schedule events based upon the RTC.

If anybody is interested in providing suggestions or assistance to me, I'd
be more than happy.

Thanks to those who respondent to my question.
