Hi,

When running through crontab, the environment is not set (as opposed to you running the script from your shell).

The 1st line of your script should be:
#!/bin/sh

And you might want to replace 'pwd' with '/bin/pwd' or copy the 'PATH' line from your profile and make it the 2nd line of your script.

Cheers,
Wout

Hi,

how did you schedule the job - and is the cron daemon running?

Hello,

1) The script needs a she-bang line at the top (e.g. #!/usr/bin/sh) and should exit at the bottom.

2) Ensure the name of the user whose crontab you added the script to appears in /var/adm/cron/cron.allow.

3) Ensure the user designated to execute the script via cron has read/execute permission on the script as well as the directory hierarchy containing it.

4) Restart cron via '/sbin/init.d/cron stop && /sbin/init.d/cron start'.

5) In this instance, 'pwd' is in '/usr/bin', which is part of cron's default PATH. But if an executable appearing in the script to be executed by cron weren't in '/usr/bin' or '/usr/sbin', you would have to explicitly add its directory to the PATH.

Hi,

maybe the problem is: what should the 'working directory' be, when running this script through cron?

Test with 'cd /tmp' then 'pwd'

...and check the mail to the user of the cron job to be executed; when you do not redirect output - as in your example - output will be mailed to the user.

Hi,

please post the output of the following commands

whoami

ll /tmp/test_script

crontab -l | grep test_script

ps -ef | grep cron

>I have checked log

I assume that was /var/adm/cron/log ?

>PCS: 5) In this instance, 'pwd' is in /usr/bin, which is part of cron's default PATH.

Actually pwd is a shell builtin.

[Rasheed Tamton]

#vi /tmp/test_script
pwd > /tmp/path.txt

Can you also include date command just before the pwd so that you would be able to see whether it is run or not.

#vi /tmp/test_script
/bin/date >> /tmp/path.txt
/bin/pwd >> /tmp/path.txt

chmod 744 /tmp/test_script

and test it. Also check the /var/adm/cron/log file.

hi,

Can you try the following and upload the content of the generated files:

30 16 * * * /tmp/test_script 1>/tmp/output.crn 2>/tmp/error.crn

revert

kind regards
