2. i already check....

/usr/lib/ .... here no cron folder or not cron file..

actully i search cron.allow.... cron.deny...

plz. help....

cron will call syslog to report stats of cron jobs. Where syslog puts the messages depends on your exact setup. For me, cron status log messages go in /var/log/syslog, but you might have a cron specific logfile in your /var/log directory.

Often, cron will send a local email to the root user with cron errors. You'll only see this if you have local mail delivery configured so you get mails for root.

The quick-and-dirty method for seeing error messages would be to change the crontab line to:
...and wait for the program to run again, then look in /tmp/mycronlog.

General hint about cron problems: it's almost always because of the environment settings in general, the PATH variable in particular. When cron launches a job, it does so with a very restricted environment, as defined in the /etc/crontab file.

Make sure that the file you want executed has the correct "execute" permission.

chmod +x test.sh

sir i give only like

chmod 755 test.sh it is right or wrong.
or i want to give
chmod +x test.sh

premission...

plz. sir help me...

They will both set the execute bit. Please read the chmod manual page to understand what each means.

hi,

first u have to #/etc/filename.cron.
then 05 * * * * /db/app/test.sh
save it .
#crontab filename.cron

to check whether cronjob is running or not type crontab -l.

that's it!!

hello sir thank for your reply

but #/etc/filename.cron.

crontab -l just show only content of file not status...
