Cron Delete ?

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.

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?

Hi,

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

Thanks in advance.

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 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:

when i run sh /root/sd.sh

Any ideas why? - any help or thoughts appreciated

What I did in windows was create images of my drive and restore them.

in linux I am running

Code:

rsync -aAXv --exclude={"/home/*","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /* /path/to/backup/folder

and this creates a folder for me with all my files, and apparently saves meta data like permissions and paths...

Since I'm using arch and things break sometimes,I'm booted into a CLI with errors and cannot figure my way out since I'm a noob... would I be able to just delete my entire root and replace it with the rsync backup without a problem?

Hi all,
Im trying to tidy up a web scrape txt file so it just shows the URL's..
As below, I've got most with just the url but struggling to work out how to delete extra txt within a line, without deleting the whole line.
i.e a command that says.. delete from this word.. till end of line .. or delete everything between word1 and word2

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.

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
