  • Script in crontab did not run

    Posted on

    Hello,

    I have some trouble running scripts via cron. I like to run two scripts via cron. My /etc/crontab looks like:

    root@host>cat /etc/crontab
    SHELL=/bin/bash
    PATH=/sbin:/bin:/usr/sbin:/usr/bin
    
    # For details see man 4 crontabs
    
    # Example of job definition:
    # .---------------- minute (0 - 59)
    # |  .------------- hour (0 - 23)
    # |  |  .---------- day of month (1 - 31)
    # |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
    # |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
    # |  |  |  |  |
    # *  *  *  *  * user-name  command to be executed
    1 0 * * * root /root/bin/do_reposync.sh
    2 1 * * * root /root/bin/update_rhel-e-stage.sh && /root/bin/update_rhel-i-stage.sh
    
    

    The first script runs as expected. The second one not. When I run the second command in bash like:

    root@host>/root/bin/update_rhel-e-stage.sh && /root/bin/update_rhel-i-stage.sh
    

    It works just fine.

    My first guess was to check if there is a linebreak after the second command and it is. The second guess was, that I have an issue with the '&&'. So I wrote a short wrapper-script and changed the crontab to:

    root@host>cat /etc/crontab
    SHELL=/bin/bash
    PATH=/sbin:/bin:/usr/sbin:/usr/bin
    
    # For details see man 4 crontabs
    
    # Example of job definition:
    # .---------------- minute (0 - 59)
    # |  .------------- hour (0 - 23)
    # |  |  .---------- day of month (1 - 31)
    # |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
    # |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
    # |  |  |  |  |
    # *  *  *  *  * user-name  command to be executed
    1 0 * * * root /root/bin/do_reposync.sh
    2 1 * * * root /root/bin/update_multiple_stages.sh
    
    

    But again the second command was not executed via cron while running correct when executed in bash. I use vim to edit the /etc/crontab.

    The log (filtered for CROND) shows the following for the timeframe:

    Jun 16 09:10:01 rpm-repo CROND[28708]: (root) CMD (/usr/lib64/sa/sa1 1 1)
    Jun 16 09:15:01 rpm-repo CROND[28717]: (root) CMD (/root/bin/update_rhel-e-stage.sh && /root/bin/update_rhel-i-stage.sh)
    Jun 16 09:20:01 rpm-repo CROND[28732]: (root) CMD (/usr/lib64/sa/sa1 1 1)

    Jun 16 10:05:01 rpm-repo CROND[28995]: (root) CMD (/root/bin/update_multiple_stages.sh)
    Jun 16 10:10:01 rpm-repo CROND[29009]: (root) CMD (/usr/lib64/sa/sa1 1 1)
    Jun 16 10:20:01 rpm-repo CROND[29047]: (root) CMD (/usr/lib64/sa/sa1 1 1)
    

    Do anyone have an idea what is causing this issue or how to debug it?

    Best regards,
