So, what's in
"/cardprod/batches/LiveSync.sh", and is it
(somehow) doing a bunch of commands (like,
say, "stty") which make sense only with an
interactive terminal (which a "cron" job does
not have)?

Previously this was working fine. Any way the script is:
----------------------------
#This script must be invoked by crontab once every minute to process HPS embossing files
. /.profile > /dev/null

export PROC_EXEC=/cardprod/batches

#while true
#do
sleep 10
echo -----------------------------------
java -classpath /cardprod/batches/ LiveSync
echo -----------------------------------
sleep 30
java -classpath /cardprod/batches/ LiveSync
#done
-------------------------------------------

So, I'll guess that "Previously" involved a
different "/.profile" (or "/etc/profile", or
some other thing which gets sucked in
directly or indirectly by this ".profile").

Wow. I would not use a hard-coded name of
"/.profile", either. Around here, root's
home is "/root", so there is no "/.profile".
I'd think that "~root/.profile" would be more
reliable (especially on a Linux system, where
"/root" is common).

A search for keywords like, say,
cron stty
might find some examples of popular ways to
restrict execution of commands like "stty" to
interactive situations.

How do you know it's not running? Other than the extra output, it might be working fine?

>. /.profile > /dev/null

If you don't want to fix your ~/.profile, you could redirect stderr too:
. ~/.profile > /dev/null 2>&1

>This script must be invoked by crontab once every minute

Looks like it only needs to be invoked once by cron and then it does runs every 10 then 30 seconds.

Hi Denis,

The script is for moving the file from one folder to the other folder. We colud see the files are available in the generated path itself.

What is the issue with the profile? Earlier the same script was working fine. Any modification required, please let me know.

Did you redirect stderr as I mentioned?
. ~/.profile > /dev/null 2>&1

If your script isn't moving the files, change the "#!" line to add "-x" to the end. This will trace execution and may give an idea where it fails.

I tried Google with:

cron stty "Not a typewriter"

and found (among many):

which looked reasonable.

Dear All,

Issue resolved. Above mentioned file is calling a configuration file for the details. In that IP mentioned was wrong. We have changed the same.

Once again thanks....
