cron and hibernate

cron and hibernate

[Paul Y. Peng]

I have two problems with cron:

1. Where can I get cron.README? I found several places where this file is
    referred to. But I can't find it in my installation of cygwin. Running
    setup.exe shows that I have all files in Admin and Doc installed on my
    PC. I thought this file may be important for me to use cron properly.

2. Currently I just go to /usr/sbin/ and run cron directly. It works until
    after the PC is restored from the hibernate state. Both Windows task
    manager and bash+ps show that cron is a running process. But it just
    does not respond to the job in crontab. Does anybody have experience of
    this problem to share?

I am using cron/crontab with a WinXP pro on a Laptop. I checked cygwin list,
Cygwin documents and web and couldn't find answer to these problems.

Thanks.
Paul.

Yes, this is an internal problem of Vixie cron, not related to Cygwin.
AFAIK.  The same can happen on any system when e. g. the system clock is
too fast and it doesn't get corrected for a while.  If you then correct
the setting, cron might suddenly refuse to start any process.  Restarting
cron is the only option I know of.  I heard also about the same problem
when hibernating a laptop under Linux.

Many thanks to all of you who replied my email. My questions have been solved.
I found cron.README. But I also learned that cron won't work properly with
hiberate (thanks to Corinna Vinschen). I tried Igor Pechtchanski's suggestion
of using run.exe and it works perfectly for me. Stephen Powell suggested
WScript. But I am not familiar with it and haven't give it a try yet.

Paul.

How about "C:\Cygwin\usr\X11R6\bin\run.exe /c/somePath/P.sh"?

No, I just got the path wrong.  Actually it is

  /usr/share/doc/Cygwin/cron.README

Running a Visual Basic program under wscript doesn't open a window.

For example to run a sh script:

--Begin P.vbs--

Dim objShell, intErr

Set objShell = CreateObject("Wscript.Shell")
intErr = objShell.Run("C:\cygwin\bin\sh.exe /c/somePath/P.sh", 0, True)
Wscript.Quit(intErr)

--End P.vbs--

and schedule it as

"C:\WINDOWS\SYSTEM32\WSCRIPT.EXE //b c:\somePath\P.vbs"

under the task scheduler.

I should have mentioned it in the last email.

I have been using Windows own TaskScheduler so far. What I don't like it
is that it cannot run jobs silently at background, particularly when a job
is a batch file or a bash script. Whenever such a job is started, an annoying
DOS window pops up and it also occupies my taskbar.

Paul.

How about Windows own TaskScheduler?

Interesting. In my cygwin installation, I don't have cron.README in
/usr/share/doc/. But I have a directory cron and a file README in cron.
Is this the file cron.README?

Thank you for this definitive but negative answer. It saves me time to try
in vain. Are there any alternative ways to do the same thing as cron? I
only heard about WinCron. Thanks.
