How to detect and fix why crontab job is not executed?
I have set several cron jobs. I recently added a new cron job that copies a file of last day from another server and is executed each day (for example at 04:00 am) but when I check next day the file hasn't been copied.
I'm working in GNU/Linux CentOS (2.6.32) system.
The files that I need to copy are created in the origin server before 23:00 hours.
I had the cron job like below: (The first line is the job that fails. related script to copy the files is script1.sh)
When I checked next day about 11:00 am I see the file wasn't copied, I edited cron job to be executed at 11:10 am and the file was copied successfully.
The script1.sh content is this:
The files to be copied have in their name the format Logfile.2018-01-17

The .profile file should be read when the user logs in. So, there should be no need to execute .profile file again in a cron job (since the cron job is run after the user logs in). Doesn't the cron require login from the user. Then, from where does the cron execute? Please help!! (1 Reply)

CRONTABS(4) Crontabs users' Manual CRONTABS(4)NAME
crontabs - configuration and scripts for running periodical jobs
SYNOPSIS
run-parts [--list|--test]<directory>
DESCRIPTION
Crontabs is a historical name for the run-parts script and the system crontab. The run-parts script runs all executables in the specified
directory. Run-parts runs all executables in the specified directory. The execution of files can be allowed or denied by creating file
jobs.allow or jobs.deny which worked similar as other allow/deny config files. The file must be created in the specified directory.
--list print names of all files (not limited to executables), but don't run them. This option can't be used with test option.
--test print names of files, which would be run.
Randomization of jobs can be configured in the /etc/sysconfig/run-parts file. To enable randomization of jobs, set the RANDOMIZE
parameter to 1 and set the RANDOM parameter to an integer which determines a random seed. Additionally, you may configure the RAN-
DOMTIME parameter (again, by specifying an integer) to provide an additional level of randomization. Jobs are not randomized when
the RANDOM and RANDOMTIME parameters are set to 0. Values in these two parameters must be set to 1 or larger to provide a good
enough randomization.
Randomization of cron jobs can be useful for shared networks, where multiple cron jobs executed at once can cause spikes in traffic,
especially during daily jobs. With randomized jobs, the workload is evenly distributed throughout the day.
EXAMPLE OF CONFIGURATION FILE
RANDOMIZE=1
RANDOM=4
RANDOMTIME=8
Historically the crontab file contained configuration which called run-parts on files in cron.{daily,weekly,monthly} directories. These
jobs are now run indirectly through anacron to prevent conflicts between cron and anacron. That means the anacron package has to be
installed if the jobs in these directories should be running. Refer to the anacron(8) how to limit the time of day of the job execution.
EXAMPLE
/etc/cron.daily/jobs.deny could contain for example 0logwatch which forbid execution of this script.
