cron running but not executing user crontab

cron running but not executing user crontab

[Chris Johnson]

Bit of a conundrum here.  Running WIN7 and cygwin64.  Have the terminal 
running and Perl is installed and runs.  AFAIK, that all works.  Used 
cygrunsrv to get cron going.  I can see cron in a ps -af in the 
terminal.  I set up a crontab for my user and it's in /var/cron/tabs by 
using crontab -e.

Doesn't seem to be running anything in the crontab.  I had wanted to run 
a Perl script in a Windows Directory outside the cygwin structure but 
using the /cygdrive/c etc path.  Ain't working.  Even tried the simplest 
thing I could think of and created a line date > dt.txt on it.  
Normally, under *nix this  would put the results of date in dt.txt in 
the home directory.  Not there.

Just isn't running anything as far as I can tell.

Any suggestions.  I'd like to get this working.  Want am I missing? 
Help  appreciated.  Thank you

Use /proc/cygdrive/c/... in case it ever changes, and specify absolute paths for
scripts and commands, as only minimal environments are setup, and
non-interactive shell startup scripts run.
Might need to specify other environment variables required in the crontab.
Ensure your perl script has Cygwin +x permissions and hashbang line.

Add cron users to /var/cron/cron.allow (and maybe also a cron group), or touch
/var/cron/cron.deny to allow all users: see crontab(1).
Check /etc/crontab and /etc/cron.d/* are owned and writable only by the crond
user if they exist; /var/run/cron.pid and /var/log/cron.log exist and are owned
and writable only by the crond user; /var/cron/tabs/* exist and are owned by
their users and writable only by their owners; /var/run/cron.pid contains the
cron pid, and see what's in /var/log/cron.log.

Not sure if I remember this right, but there is a cron-config in the
package, and that is what you are supposed to use to install it as a
service (and set a proper daemon user, file & dir access, etc.)  You
probably will have to undo whatever you did with cygrunsrv.

Better read /usr/share/doc/Cygwin/cron-4.1-65.README to be sure.

Hope this helps.
