Good day! I don't know what's the problem with this, I have two (2) entries in Crontab, these 2 entries are scripts which I've created. I need these 2 for automatic backup and maintaining only 3 files under a given directory. Here are my entries below, and they are NOT executing:
Any advise please. Btw my Cron is Version V5.0
Thanks in advance!

To add-up to, I've tried entering this below in Cron and YES it worked, but not for my 2 scripts. All permissions were already set to 777 even the sub-directory itself.
I was wondering if itīs possible to cron job not to run on a certian day and time. Iīve got a job that runs everyday at 08:00
but would like it not to run on the 20:th between 08:00 and 10:00
Anyone know if this is possible, and if. How do i do it?
regards...

Where can someone find info on Cron Jobs? Very new to UNIX and the PC I inherited looks to have several of them. Looks like they are some kind of background program that runs automatically at specified times. Would like to delete some of them and know more about them. (6 Replies)

cron
CRON(8) System Manager's Manual CRON(8)NAME
cron - daemon to execute scheduled commands (ISC Cron V4.1)
SYNOPSIS
cron [-l load_avg] [-n]
DESCRIPTION
Cron should be started from /etc/rc or /etc/rc.local. It will return immediately, so you don't need to start it with '&'. The -n option
changes this default behavior causing it to run in the foreground. This can be useful when starting it out of init.
Cron searches /var/spool/cron for crontab files which are named after accounts in /etc/passwd; crontabs found are loaded into memory. Cron
also searches for /etc/crontab and the files in the /etc/cron.d directory, which are in a different format (see crontab(5)). Cron then
wakes up every minute, examining all stored crontabs, checking each command to see if it should be run in the current minute. When execut-
ing commands, any output is mailed to the owner of the crontab (or to the user named in the MAILTO environment variable in the crontab, if
such exists).
Additionally, cron checks each minute to see if its spool directory's modtime (or the modtime on /etc/crontab) has changed, and if it has,
cron will then examine the modtime on all crontabs and reload those which have changed. Thus cron need not be restarted whenever a crontab
file is modified. Note that the Crontab(1) command updates the modtime of the spool directory whenever it changes a crontab.
Daylight Saving Time and other time changes
Local time changes of less than three hours, such as those caused by the start or end of Daylight Saving Time, are handled specially. This
only applies to jobs that run at a specific time and jobs that are run with a granularity greater than one hour. Jobs that run more fre-
quently are scheduled normally.
If time has moved forward, those jobs that would have run in the interval that has been skipped will be run immediately. Conversely, if
time has moved backward, care is taken to avoid running jobs twice.
Time changes of more than 3 hours are considered to be corrections to the clock or timezone, and the new time is used immediately.
PAM Access Control
On SUSE LINUX systems, crond now supports access control with PAM - see pam(8). A PAM configuration file for crond is installed in
/etc/pam.d/crond . crond loads the PAM environment from the pam_env module, but these can be overriden by settings in the crontab file.
SIGNALS
On receipt of a SIGHUP, the cron daemon will close and reopen its log file. This is useful in scripts which rotate and age log files.
Naturally this is not relevant if cron was built to use syslog(3).
CAVEATS
In this version of cron, /etc/crontab must not be writable by any user other than root. No crontab files may be links, or linked to by any
other file. No crontab files may be executable, or be writable by any user other than their owner.
