Crontab -e

Hi
On Solaris Sparc 2.6, when I typed crontab -e
I get a number 1 displayed on the terminal.
When I pressed enter, a question mark is shown. I'm confused.
I am guessing that a VI editor for cron is not set. If this is the case, how can I configure a VI editor for crontab -e
Thank you
Cindy

Hi,
Set and export the EDITOR environment variable to use vi to edit
crontab files.
If you are using the Bourne or Korn shell, enter the following:
# EDITOR=vi
# export EDITOR
If you are using the C shell, enter the following:
# setenv EDITOR vi
Revert back.
Thanks.

Java running under linux with crontab

I'm having a problem:
i want to run a java program under linux with crontab.
my classes are in a directory and aren't in a package. i run em by invoking ./start which is a small script that i wrote. The script is in the same dir as the classes and invokes java by "java Main >>logjava.txt " but this doesn't seem to work all i get is an empty logfile
i need to run the program every day at 0800 so i inserted the following in crontab:
0 8 * 1-5 /var/"path"/start > logjava (where path is the path to the classes dir)
if i run the cmdline from anywhere on the prompt i get the result i want. I think it's because the cron runs it from the root dir thus making java unable to find the classes
Any suggestions would be welcome. or can some1 tell me how to make linux executables from the java (i usually use jsmooth for the windows exe)

You can execute several commands in the process started by cron. You separate them using semicolons.
Have you tried a cron entry like this:
0 8 * 1-5 cd /var/"path";pwd;echo $PATH; ./start > logjavaOr, you may need to make sure the process started by cron gets the same environment as your interactive shells do, by explicitly loading your setup or .login scripts:
0 8 * 1-5 . $HOME/.setup;cd /var/"path";pwd;echo $PATH; ./start > logjava

How to schedule a crontab job for a script?

Hi,
Can anyone help me in this?
Actually, i want to schedule a crontab job for a script.
the script needs to check for a file in a diectory.
When ever a particular file in a directory is created, then i need to run that script. (creation time of file and execution time of script must be same)
So, how can i do this?
any suggestions?
Thanks,

crontab manual http://linux.about.com/od/commands/l/blcmdl5_crontab.htm
if you need check files on OS, crontab is good way... to do
Example: checking trace file older 30 days and remove (00.00 -> every days )
file.sh:
........begin file......
#!/bin/sh
find PATH/udump -name '*.trc' -type f -mtime +30 -exec rm {} \;
........end file......
$ chmod 750 file.sh
$ mv file.sh /home/oracle/file.sh
-- edit crontab
$ crontab -e
0 0 * * * /home/oracle/file.sh
-- list crontab
$ crontab -l

Problems of running java program by crontab in Linux

I have a java application program which runs great when started in command line, or in shell script, or Perl. However, when it is started by crontab in Linux, it stops in the middle when images are to be generated. I guess there might be some settings I need to handle in order to run this java application by crontab. We tried to start the shell script or Perl program in which the java program was invoked, but still didn't work.
This may be a littler stretching. Does anyone have similar experience and success?
Thanks in advance.

Scheduling crontab to send an email with an attachement?

(second post, 1st in wrong forum)
Hey everyone,
Does anyone know how to set up a command to send an email with an attachement? From what I've been informed so far, I inputed:
0 22 * * * (cat mailtext; uuencode filename.txt filename.txt) | mail -s 'here is the backup log' [email protected]
#The first filename.txt will also have the file path preceding it.
I done all this and still no email. Do I have to enable smtp or set up the mail server?
Any help would be much appreciated. Thanks!
Xserve Mac OS X (10.4.2)

What you're describing doesn't make any use of Automator.
That being said, using command line "mail" does require that the Unix mail system be set up. This site has a utility for doing that.
If you want to use Automator (the subject of this forum), you might try this:
Create a new Automator workflow with these three actions:
Get Specified Finder Items -- put your desired attachment(s) in the list
New Mail Message -- fill in all appropriate fields
Send Outgoing Messages
Once you confirm that the workflow works, save it as an application. Then you can make it repeat with cron like you specified in your posting, but with the Automator task. E.g., if you saved it to the desktop, and with the name AutoSendDailyReport, edit your crontab:
<pre>0 22 * * * ~/Desktop/AutoSendDailyReport.app/Contents/MacOS/AutoSendDailyReport</pre>
Note that in this example, you'll need to be logged in at the time the cron job runs, so that the applications can run. It will automatically launch Mail, if not already running, and send the email.
Alternatively, you can use iCal to schedule the task: set up a repeating event, with the alarm set to open the workflow app created above. Once again, you'll need to be logged in at the time the mail is to be sent.

Issues with crontab use

I'm running 10.3 and I need to automate several tasks in off-peak hours. I'd like to run these tasks around 4am once/week. I've created a shell script that runs fsck, repairs permissions, updates prebindings, cleans some temp directories, and some other misc stuff. The shell script works fine when I run it manually using:
sudo ./myshellscript.sh
As you can notice my script requires elevated privileges to run most of its tasks. The root user is NOT enabled, but I was wondering if I could still run a cronjob as root. I installed Cronnix and opened the root crontab & of course it gave me an error basically saying the root crontab was empty. At this point, I tried scheduling for various times for testing, but no matter what time that I give it the cronjob never runs. Every line of my shell script outputs to a log file, but when the task is scheduled with a root cronjob the log file is never created. If I run it manually, the log file is created just like I want.
My questions are:
1. Can you run a cronjob as root even if the root user is not enabled?
2. Does anyone else have an idea as to how I can get this to work?
I know it must be possible. Doesn't OS X have a daily, weekly, & monthly cronjob that run automatically? I certainly didn't see those listed under root.
Any help is greatly appreciated.

i'd advise not running any of those tasks every week.
the periodic tasks run on a schedule anyway. why force them each week? if they're running at times your server is busy or interfere with your ability to access services, change the times they run.
updating prebinding is also unnecessary. here's an old link that explains what the function does: prebinding explained. if an app really needs it, the OS will take care of this for you. how many applications are you installing on your server, and how often?
repairing permissions is the same: don't do it unless something is wrong. specifically, only repair perms when you suspect incorrect permissions are your problem. for more on this, see repairing permissions is useless.
and, like davidh said, you can't fsck your boot drive. that will fail every time, so don't do it.
if you have a need for some maintenance scripts that actually may help, please ask. i think some folks on the boards can help. i'll dig up some, as well.

Problem setting up crontab for cyrusimap

Greetings all.
I've just finished setting up OS X Server 10.4.10 on an intel mac, and was trying to setup a crontab for cyrusimap to make sure that all mail for JUNKMAIL and NOTJUNKMAIL users is deleted automatically using ipurge.
I created the following crontab file:
<pre>
0 0 */0 * * /usr/bin/cyrus/bin/cyrus-quota -q
30 1 * * * /usr/bin/cyrus/bin/ipurge -f -d 1 user/junkmail user/notjunkmail
</pre>
And then tried loading it in via:
<pre>
sudo crontab -u cyrusimap <PATHTOCRONTAB>
</pre>
However crontab just hangs hogging 90%+ of the CPU!? The permissions in /var/cron/tabs seem ok, with full read/write for root.
Any ideas? Thanks in advance,
Mezza

Mezza,
cron is not used by default in OS X although it is certainly supported.
See http://www.afp548.com/article.php?story=20050620071558293
Since you did not explicitly state the "path to crontab"
I wonder if you might be trying to run root's crontab as user cyrusimap, which of course won't work. See the crontab manpage for a possible exception although I wouldn't recommend it.
The crontab file for cyrusimap is empty by default in 10.4 server

Shell Script to grep Job File name and Log File name from crontab -l

Hello,
I am new to shell scripting. I need to write a shell script where i can grep the name of file ie. .sh file and log file from crontab -l.
#51 18 * * * /home/oracle/refresh/refresh_ug634.sh > /home/oracle/refresh/refresh_ug634.sh.log 2>&1
#40 17 * * * /home/oracle/refresh/refresh_ux634.sh > /home/oracle/refresh/refresh_ux634.sh.log 2>&1
In crontab -l, there are many jobs, i need to grep job name like 'refresh_ug634.sh' and corresponding log name like 'refresh_ug634.sh.log '.
I am thinking of making a universal script that can grep job name, log name and hostname for one server.
Then, suppose i modify the refresh_ug634.sh script and call that universal script and echo those values when the script gets executed.
Please can anyone help.
All i need to do is have footer in all the scripts running in crontab in one server.
job file name
log file name
hostname
Please suggest if any better solution. Thanks.

Problem Crontab vs Java 1 4 2 & Socket

I've created a shell script that calls the java program :
PATH=/usr/lib/java:/usr/lib/java/bin:/usr/java142:/usr/java142/bin:$PATH ; export PATH
cd /usr/dconn
java -cp DConnection.jar DPackage/DConnection
The jar en script file are in the same directory.
In the java program a socket connection is made and communication is started with the remote system.
When executing this script at the prompt, there is no problem. I can send data and receive.
The following step is to schedule this script :
SHELL=/bin/sh
MAILTO=root
# check scripts every minute
*/10 * * * * /usr/dexxconn/startdexx.sh
At first there was java 131 installed on the linux system. And there was no problem with the program. When I began using java 140 (on windows) because I needed some new String methods, the scheduler mycron didn't properly executed my program.
The output of the program is normally seen in the mail of the root. But nothing gets in the mail. So I killed the process for that java program and I got output in the mail from the root.
I can derrive from that mail that the java program makes a socket connection, but does not communicate with the remote system. I can't send data or receive.
Has anyone any idea to solve this problem, is it because of crontab,java 140, java 142?

Forgot to mention. When I had these problems with java 131 on linux I installed java 142 and then I got the earlier described problem.

[SOLVED] Crontab entry ignored

I'm running cronie. My root crontab has an entry to run tarsnap every night, which is ignored.
The tarsnap line works when run in a terminal and the other entries work as well.
I tested it by altering the time to make it run immediately but nothing happens - no reported errors as far as I can see.
Here is my root crontab:
# backup /etc nightly
30 3 * * * rsync -a /etc/ /databackup/etc
# Correct clock each morning
00 5 * * * rdate -ncv uk.pool.ntp.org ; hwclock --hctosys
# update mlocate database each morning
00 4 * * * updatedb --prunepaths '/tmp /proc /mnt /var/tmp /databackup'
# tarsnap backup
00 3 * * * /usr/bin/tarsnap --exclude /home/ac/.mozilla --exclude /home/ac/.cache -c -f arcadiabackup-`date +%y%m%d` /home/ac
MAILTO=me@mydomain

Are you sure that cronie is running?
# systemctl status cronie.service
Yes.
Also, please use code tags.
Don't know what you mean by this.
Anyway, I found a work-around: I made a bash script in /root and that runs the command without problems.
