I am facing some problem while executing the process thru cron. My execution
scripts (KORN shell) will be something as below:

echo U$(tput kf9)$(tput kf9)|/prog/bin/prog1.exe M A 1>/prog/log/cron.log

In my cron.log, I can see that the 1st input parameters is not passing in to
the program correctly therefore it is prompting invalid entry. However, when
I execute the program manually thru command line,it is working fine.

Anyone have any clue what cause the problem?

Which OS?

cron usually executes scripts with a Bourne shell (you'll get a warning after running crotab -e), unless you explicitly add something like #!/bin/ksh as the first line of your script.

> I am facing some problem while executing the process thru cron. My execution

When you execute it manually via a telnet/ssh session you probably have
a TERM value set, which defines that `tput kf9` outputs. When it runs
via CRON then TERM is possibly not set or set to some system default.

Try -
(export TERM=vt100; echo U$(tput kf9)$(tput kf9)|/prog/bin/prog1.exe M
A) >/prog/log/cron.log

It also looks like it is looking for a parameter/switch.

When executing from cron, you must specify all aspects of the operating
environment. Cron doesn't know much about anything if you don't tell him.

Thank you for your response.
we are using TERM=wy150. I have checked that and it is exported correctly.
Any other clue to resolve this issue?

I am using UNIX-HP. In my scripts, the first line already stated #!
/usr/bin/ksh. Any other clue to resolve this?

Problems with running Informix programs via cron almost invariably boil
down to environment in some extended sense of the term environment.
Here, that could include current directory, uid, gid, aux gid, umask,
tty device, and so on - as well as the environment variables.

First step - analyze what environment variables are set in the working
environment, from the command line.
Second step - establish what environment variables are set in the cron
environment.
If the problem isn't obvious when you compare the two lists, then try
eliminating variables from the command line environment, heading towards
the simpler cron environment.

If you get to identical environments and the problem still occurs, look
at other aspects of the environment, such as uid, ...
If you still have problems after reconciling all the environment, it is
most likely something to do with the terminal handling - and the tty.
Do ensure that you get the correct output from your echo command - pipe
it through tee perhaps, to trap the output before sending it to the program.

Further analysis done, it is comfirm that the cause was due to the $(tput kf9)
not pass to the calling 4GL program correctly.

after a crontab log showing the following:
stty: : Not a typewriter

Any idea to resolve this?
It seem like the cron process can't recognize the $(tput kf9) correctly.
I am not the unix expert, but you please show me how to handle all these tput
command and terminal setting handling especially in cron process.

Just put it all in a script and run that script from cron instead...
