I want my cron job to run at every 2 minutes interval in all hours,
days, months etc.
OS - Sun Solaris
Release Level -5.10
I tried with */2 * * * * filename but it failed.
How to do that?

Try 'man crontab' on your Solaris box to find out...i need to trigger a script every 20 seconds, but cron will only run every minute
The fastest I can get cron to run is once a minute. But I've got a
script (which logs people out of a chat room) which needs to fire once
every 20 seconds. How do I do this?

Have it three times in your cron script with "sleep 20" in between?

I need to run something from CRON every 10 or 15 seconds for a while. It
appears that the smallest interval I can establish for a CRON entry is once
every minute. Does anyone know how I can get a job to run every 10 or 15
seconds based on a CRON entry?
How about writing a script instead that runs in the background all the
time and uses sleep.
sleep 10 (or 15)

How can I run cron job in Linux, I need to run some job automatically
every night at 12'o clock on my RH Linux machine.
Basically what I want to do in my script is, I need to check out my
code, then build and then send an e-mail, the log of comp, can that be
possible?. also can I keep this script in my home directory or in /etc
Directory?. These four commands I need to place in that script.

I just migrated from RH Linux to Gentoo. I really like Gentoo, but am
not sure I like the default cron configuration. RH uses run-parts in
the cron-tab to activate the scripts contained in the cron.*
directories. This seems like a clear and straightforward way to run
the cron jobs.
Gentoo uses run-cron to do this. Which means that there is a cron job
run every fifteen minutes which runs run-cron and then the appropriate
files are deleted in the lastrun directory when the it is time to
re-run a job. I have a few questions about this.

I have a pressure sensor instrument with a 0 - 5v output relating to the 0 - 25mbar pressure, this is connected via a NI DAQPAD 6016. I want to be able to show the current pressure reading and also have a reading taken every 5 minutes so that I can plot a graph of the pressure change. The readings have to be every 5 mins, no closer together.
Can anyone suggest anything?

Install rancid/clogin  and have a 'clogin -c "clear host *" $router'
fired off by your unix host via cron.

I have a script that can encode a wav file to either an ogg file using

works. If I run the script using a cron job, the oggenc will run, but
the lame won't. Here are the permissions:

Well, here's how I do it (there may be other ways tough).
Define a shell script doing two things:
- set up an IDL_STARTUP environmental variable with the full path to a
IDL program (let's say is called idl_startup.pro)
- start idl
Then, in idl_startup.pro put in
[your initialization for IDL]
This way, you can put the shell script in your cron table,
and this will execute your IDL initializations, then
the program called your_program and exit...unexpected crontab jobs runnings
This may be weird but yesterday I've commented one of my crontab's
entries to avoid a program execution at 9 pm (by including '#' at the
very beginning of the line).
This morning I realized that this program has lauched automatically at
9 o'clock although I did not want it to.
Using '#' is the good way to comment a crontab entry ?
Is there any other way than crontab I don't to run a task automatically

The users' crontabs are located at /var/spool/cron/crontabs.
Maybe your job works, when you call "sh" with its absolute path

I have a Perl application that just unzips a zip file once per day.

because I receive the email every day.

Well this is weird! I'm used to odd problems when you run programs from
cron but these are almost invariably to do with file permissions or
stuff in the environment variables not matching the command line
I'm using ruby 1.8.4 (2005-12-24) [i686-linux] on a RHE 3.0 system.
The program runs fine from command line but gets nonsensical syntax
errors when run from cron.
Any idea where to look for the problem?

In ISO C, the only option, and even then it's not an ideal one, is to
have a busy-loop inside which you check the elapsed time using time()
