Script in /etc/cron.daily (Hourly,Weekly) won't Run or Execute
Symptoms:
=> Script won't Run or Execute in these Ubuntu Linux Folders
/etc/cron.hourly
/etc/cron.daily
/etc/cron.weekly
/etc/cron.monthly
Possible Check-Points
1. Make sure NO /usr/sbin/anacron existed
Otherwise, we will run "anacron" first before running "run-parts"
代碼:
$ ls -l /usr/sbin/anacron
ls: cannot access /usr/sbin/anacron: No such file or directory
$ grep "*" /etc/crontab
17 * * * * root cd / && run-parts --report /etc/cron.hourly
25 5 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 7 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
^^^^^^^^^^^^^^^^^^^^^^^^^
2. Rename/Remove "dot" and ".sh" from your script filename
Some run-parts parameters has filename name space constraints:
e.g.
代碼:
$ cd /etc/cron.daily/
$ sudo mv daily_backup_userfolder.sh dailybackupuserfolder
3. Make your script executeable
Of course, make them with +x permission.
代碼:
$ cd /etc/cron.daily/
$ sudo chmod 755 <YOUR SCRIPT>
4. Specify proper shell directives (e.g. #!/bin/sh or #!/bin/bash)
Finally, check if there is shell directives at first line.
代碼:
$ cd /etc/cron.weekly
$ sudo vi <YOUR SCRIPT>
# (... Add a #!/bin/sh at first line ...)
