Perplexing Cron Audio Problem

Hi,

i have a small problem on my system... I recently wrote a small bash script and added it via crontab -u root -e and it's executed as it should.
Then a few days after i did edit my bash script, but once it is run by cron it doesn't reflect the changes i made to the script. I did manually restart crond, tryed sync, moved my script, renamed it even rstart the server - no success.
If i run my script manually it returns me the expected output.
part of my script (/root/sd.sh):
Code:

#!/bin/sh

echo -n "Checking Raid... "
RAID=`tw-cli /c0/u0 show status | cut -c17-31 | grep -ci OK`
RAIDSTATUS=`tw-cli /c0/u0 show status | head -n1 | cut -c17-31`
if [ $RAID -eq 0 ]; then
  VERIFYING=`tw-cli /c0/u0 show status | cut -c17-31 | grep -ci VERIFYING`
  REBUILDING=`tw-cli /c0/u0 show status | cut -c17-31 | grep -ci REBUILDING`
  if [ $VERIFYING -eq 1 ]; then
    CURRENTSTATUS=`tw-cli /c0/u0 show verifystatus | head -n1 | cut -c46-49`
  fi
  if [ $REBUILDING -eq 1 ]; then
    CURRENTSTATUS=`tw-cli /c0/u0 show rebuildstatus | head -n1 | cut -c47-50`
  fi
  echo "Raid is busy (Raid $RAIDSTATUS$CURRENTSTATUS)"
  exit 1
fi
echo "Raid is idle (Raid $RAIDSTATUS)"

echo -n "Checking for logged in Users... "
USERS=`who | wc -l`
if [ $USERS -gt 0 ]; then
  echo "Users online"
  exit 1
fi
echo "None logged in"

crontab -l :
Code:

root@monster:~# crontab -l
# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command
*/10 * * * * /root/sd.sh | logger
*/30 * * * * /root/dropbox.sh > /dev/null

syslog:
Code:

Mar 21 09:10:01 monster /USR/SBIN/CRON[3998]: (root) CMD (/root/sd.sh | logger)
Mar 21 09:10:01 monster logger: Checking Raid... Raid is busy (Raid )

Mar 21 09:30:01 monster logger: Checking Raid... Raid is busy (Raid )

when i run sh /root/sd.sh
Code:

root@monster:~# sh /root/sd.sh
Checking Raid... Raid is idle (Raid OK)
Checking for logged in Users... Users online
root@monster:~#

Any ideas why? - any help or thoughts appreciated

Hello,

I cannot understand why the symlink I have put in /etc/cront.daily won't work. It is very possible I am wrong, but my understanding is that cront.{daily,weekly,monthly} works fine with symlinks.

Basically it is double symlink-ed. ls -la on /etc/cron.daily looks like this:

Code:

... 
lrwxrwxrwx  1 root root    49 Nov 27 18:26 rsync_mysql_backups.sh -> /home/myuser/scripts/bash/rsync_mysql_backups.sh
...

Now, ls -la on /home/myuser/scripts looks like this:

Code:

...
lrwxrwxrwx 1 myuser myuser    26 Sep 20  2013 scripts -> /media/md1_storage/scripts
...

I couldn't see anything suspicious in syslog, so I installed postfix in the hope that I will get some sort of information there. Nothing... I also redirected the output of the script to a file in /home/myuser/log.txt but nothing there. The file was not even created.

I am not doing anything mad in the script, I am just synchronising a local directory with a remote one like this:

Code:

/usr/bin/rsync -avzx -e 'ssh -i "/home/myuser/.ssh/myremotehost/id_rsa"' /media/md1_storage/backups/stuff/ myuser@myremotehost:/srv/backups/stuff/ >> /home/myuser/log.txt 2>&1;

As other people suggested in similar threads, I have verified that
Code:

test -x /usr/sbin/anacron

is false, which will result in the execution of the second part of the entry in /etc/crontab:

Code:

25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )

Any input will be much appreciated. I know I am doing something wrong, but I just cannot see it right now... How can I gather more debugging which will help me understand what's going wrong?

Thanks!

Hi Team,

I have setup few jobs with separate log files and separate EMail ID's for each job in my cron.
If something fails in these jobs, cron is delivering a mail to the mail ID that I have configured in cron as MAILTO= ( can be seen in crontab -l).

In this course, few passwords are also being returned as output from failed jobs which are being emailed to MAILTO ID.

I want to suppress the password while sending the cron output to the MAIL ID's.
Can anyone please guide me in this?

Note: I am not root user so I don't have access to /etc/syslog.conf.

Hi

When i run this command manually on Centos 6.6 it works:

Code:

/usr/bin/find /backup/ -type d -mtime +1 -print0 | xargs -0 rm -rf

but as a cron job it doesn't as i can see a folder with files there from Mar 28:

Code:

55 5 * * * /usr/bin/find /backup/ -type d -mtime +1 -print0 | xargs -0 rm -rf

And here are the logs from cron that it is executing this at the correct time :

Code:

Mar 30 05:55:01 server CROND[9526]: (root) CMD (/usr/bin/find /backup/ -type d -mtime +1 -print0 | xargs -0 rm -rf)

Any ideas why?

Thanks

I found this command on my crontab, i know what is "30 3 * * * /usr/bin/php5 /home/super/public_html/index.php" but what is "Cron Delete" ?

"30 3 * * * /usr/bin/php5 /home/super/public_html/index.php Cron delete"

I have a small script1 scheduled via cron to run every 20 mins to invoke script2 if script2 is not running.
When i run script1 from cmd line it works fine but when it is scheduled via cron it doesn't work. Not sure what am i doing wrong here.
I even tried to use absolute path.

Script 1
Code:

#!/bin/sh
/bin/ps -ef |/bin/grep script2.sh |/bin/grep -v $$ > /dev/null 2>&1
if [ $? -ne 0 ]
then
/usr/bin/nohup /home/user1/script2.sh &
fi

Hi All,

I have perl script which I am trying to run on 1st Monday via cron job.
So I scheduled it as follows:

0 0 1-7 * * root ["$(date '+%a')" = "Mon"] && /usr/bin/perl script.pl

But then it didn't run so checked cron log and it seemed like its missing the command. so added a \ in front of %a and then it picked up the whole command as per cron log.

But still it didnt ran the script. I then change the script to just && echo "test">/tmp/test

Still nothing. if I run it as /usr/bin/perl script.pl it runs though

Thanks in advance.

System Info:

I have normal user in CentOS 7 whose name is "mostafa" (the name of the account).

I naturally have another user called root with all privileges. User "mostafa" is put into sudoers file, too.

The OS is installed in VmWare, so the system is all mine.

Problem:

Now I create a file with touch file.sh and put a command in it, but when I want to run it with Code:

sudo ./file.sh

, an error is shown that the command Code:

./file.sh

does not exist. But if I Code:

 sudo chmod 777 ./file.sh

then it gets run. My question is that, why should I use Code:

chmod 777

when I myself have created the file, and I am in sudoers.

Can anyone explain me why shuold I still use Code:

sudo chmod 777

when the creator of the file is me.

I need to clean-up some folder. I have a cron job which uses find command to find and delete 25 days older file.

Code:

find $FOLDER_PATH/$FOLDER -depth -regex  ^$FOLDER_PATH/$FOLDER/[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+$ -type d -mtime +25  -exec ls -ld {} \;   >> /tmp/deleted_folders.log

When this running it occupies 1-3% of cpu. And it may take longer time based on the folder size.

Is it ok to have find command running as cron job ?

Hi,

I have the following entry in crontab.

30 17 * * * rm -rfv /backup/alfresco_bkp/alf_data_backup/`date -d '-2 days' '+%d%m%y'` {} \; >> /backup/alfresco_bkp/alf_data_backup/deletionLog.log 2>&1

This command executes properly when run manually. However, it does not work in crontab. Can some one please tell the reason and solution for this?
There some other entries as well in the crontab and are working fine.

Thank you in advance !!!
