[techtalk] cron.hourly vs cron.daily timing

[Nancy Corbett]

It depends on how the cron is set up. The exact hour of the day is set
in the crontab file.  You can check it out yourself by entering crontab -e
at the command line.  It will bring up the list of scheduled cron jobs.
Below I have an example of how crons are scheduled.  There are 3 cron jobs
set up in the example for 1am, 2am and 3am, respectively, at exactly the
hour.  Since there is no designation for month, day or day of the week,
the cron will run every time the clock turns to 1, 2 or 3am.

Hope this helps.

Example:

# Six fields per line, as follows
#
#  minute (0-59),
#  hour (0-23),
#  day of the month (1-31),
#  month of the year (1-12),
#  day of the week (0-6 with 0=Sunday).
#  command
0 1 * * * /test/nancy/bin/cleanlogfiledir      -P /test/nancy/outdir
0 2 * * * /test/nancy/bin/cleandatasourcefiles -P /test/nancy/outdir
0 3 * * * /test/nancy/bin/cleandatabasetables  -P /test/nancy/outdir
