Mail Everyday Without Cron

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 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.

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... "

if [ $USERS -gt 0 ]; then
  echo "Users online"
  exit 1
fi
echo "None logged in"

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

Any ideas why? - any help or thoughts appreciated

Hi All,

I have facing a problem with cron job.
Actually on the client server there are some cronjob scheduled
as follows:

@daily sh_file.sh 2>&1>> /dev/null #Contact: vali.zachia@gmail.com
@hourly php demo.php 2>&1 >> /dev/null
10 2 * * * wget --no-check-certificate url 2>&1 > /dev/null #Cron IE
10 2 * * * wget --no-check-certificate url 2>&1 > /dev/null #cron EN
@daily sh script.sh
@daily sh script.sh
@daily sh script.sh
@hourly wget --no-check-certificate url 2>&1 > /dev/null
@daily wget --no-check-certificate url 2>&1 > /dev/null #Cron Poland
@daily wget --no-check-certificate url 2>&1 > /dev/null #Cron Norway
@daily wget --no-check-certificate url 2>&1 > /dev/null #Cron Portugal
10 2 * * * wget --no-check-certificate url 2>&1 > /dev/null #Cron GR
@daily wget --no-check-certificate url 2>&1 > /dev/null
@daily wget --no-check-certificate url 2>&1 > /dev/null
@daily wget --no-check-certificate url 2>&1 > /dev/null #Denmark



Cronjobs are scheduled daily/hourly.

But what happends after every hour/day there is a blank file created in a folder .

like :
hourly.1

hourly.2
hourly.3
hourly.4

and so on similary for daily scripts.

I am not sure whether these are created by cron job
So please clarify whether cronjob provides some thing like above or it is the code problem

Hi,

In Solaris, I submit cron job using "cron -e". In RedHat Linux, how to submit a cron job?

Thanks in advance.

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

CRON LOG :

Hi All,

I have two scripts, the aim of these two scripts is, to check whether a particular script is running or not, if it wont runs, then throw a mail.

How i Achieved this output is, I wrote first script.

I created an infinite while loop which performs below steps

1. It creates a touch file
2. Triggers the script which needs to be monitored if its working or not.
3. Removes the touch file.

If the second step fails, then the remove file command will not happen and the script will stuck there itself.

I created an another script which checks the creation time of the touch file and if it is more than ten minutes, it means the second step in the first script is hanged, which also means that particular script is not working.

So if the creation time is more than 2 minutes the second script will throw a mail.

Below are the two scripts.

Code:

#!/bin/ksh



userid="chansd"

filename="/apps/log/check.txt"

while true ;do
touch $filename
pass=`/apps/eDMZ/call_st.ksh $userid`
sleep 20
rm $filename
done

Below script checks the file creation time and throws email if it is older than 2 minutes
Code:

#!/bin/ksh


filename="/apps/log/check.txt"

if [ -f "${filename}" ]
then
if test "`find $filename -mmin +2`"
then
echo "script is not working ! Please act on it" | mail -s "Script  is not working" Example@mail.com
fi


else

        exit 1

fi

What im going to do is

1. I am going to run the first script in background so it runs forever.
2. I am going to run the second script in cron forevry 5 mins to check the file creation time.

3. So if the first script hangs . I will kill the process using process id and after the issue resolves with the inner script, I will run the main script again.

I am new to Linux, Please let me know if this approach will work as expected.

I'm running LinuxLite 2.0 32bit on a Dell 3000.

I have never come across anything like this and to tell you, I am stumped.

Here are the contents of my crontab file:

Code:

# 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 * * * * /usr/bin/arecord -t wav -f cd -d 42 /home/randy/Music/lanting$(date "+\%^b\%d\%y").wav

If I run this from the terminal, everything is fine. It properly records the audio:

Code:

/usr/bin/arecord -t wav -f cd -d 42 /home/randy/Music/lanting$(date "+\%^b\%d\%y").wav

If I run this as it is shown in my crontab file, it records but there is no audio recorded.:


Code:

*/10 * * * * /usr/bin/arecord -t wav -f cd -d 42 /home/randy/Music/lanting$(date "+\%^b\%d\%y").wav

What could be causing this? I tried different cron settings for example 15 14 * * 2

This recorded at 2:15pm on Tuesday (today) but no audio. Yet if I run the code as mentioned above, from the terminal without the cron settings, the recording is fine.

Any ideas what I should do?

I added a cron job , but I found that even set * * * * * ~my_cronjob , it only only it at EVERY MINUTE , if I want it run at every 20 second , can advise what can i do ? thx

hello

first year of learning linux and bash script
Now i wrote a bash script with a function.
Today i recieved a email from my teacher that 1 function only can have 1 command and no more then 1?

thats a part of the script

Code:

function tx_unreachable_msg()
{
LOGLINE="[$DATE] no ip service unreachable"
typewriter "$NOIPSERVICE niet bereikbaar" .1
sleep 1 
typewriter "Mail wordt verzonden naar $email" .1
mail -s "NO ip mail error" "$email"<<EOF
dynupdate.no-ip.com niet bereikbaar @ $DATE
EOF
}

it's part dutch part english but the point is that the first LOGLINE is forbidden in the function because i use the functie to send a mail end not to write a logline but that's a part of the command in my case?

So what does this function?
If the no ip service is unreachable then it's write to /etc/var/log/no-ip and after the sleep it's send a simpel mail to the adres in the variabele mail.

i read here at the first line:
Quote:
Shell functions are a way to group commands for later execution using a single name for the group.
so is it true that my function is wrong and so no can someone point me to a website where it's say that more commands are allow in 1 function0
