/opt/OV/bin/ovdumpevents > events
echo "now processing events"
more events |grep OVpatternDelete >list
Value=$(tail -1 list|awk '{print $8}')
EvDate=$(tail -1 list|awk '{print $3, $4, $5, $6, $7}'|cut -c -8,10-)
if [ ${Value} = "OVpatternDelete" && ${Date} = ${EvDate} ]
then
echo "processing mail"
else
echo "no action"
fi

Hi,
replace
if [ ${Value} = "OVpatternDelete" && ${Date} = ${EvDate} ]
by
if [ ${Value} = "OVpatternDelete" -a ${Date} = ${EvDate} ]

now processing events
ecschk.sh[10]: Jan: A test command parameter is not valid.

Also please tell me the diff in && and -a.i dont have any experience in this.i just simply followed some sytax from google.

THANKS

one of the variables you set is probably evaluating to nothing - so you might want to try:

if [ "${Value}" = "OVpatternDelete" -a "${Date}" = "${EvDate}" ]

The && syntax for "and" doesn't work in a test statement in the HP-UX POSIX shell - the code you got from google was probably for another shell which supports both syntaxes...

If you want to use &&, you need to use [[ ]]:
if [[ "${Value}" = "OVpatternDelete" && "${Date}" = "${EvDate}" ]]; then

Typically bin isn't a real user. How are you logged into bin?)

>"/usr/sbin/evdel.sh" returned standard error data:
/usr/sbin/evdel.sh[5]: /tmp/ActionNNM/events: Cannot create the specified file.

Does the directory /tmp/ActionNNM exist? If not, you can always use "mkdir -p /tmp/ActionNNM" to make sure.
Does that directory have the right permission?
ll -d /tmp/ActionNNM

Hi

Thanks for the quick response.

I didn't logged in as user bin.But when my application executes command as bin.

ll /tmp/ActionNNM/
total 112
-rw-r--r-- 1 bin bin 19140 Jan 5 13:19 action.log
-rw-r--r-- 1 bin bin 2580 Jan 5 13:19 action1.log
drwxr-xr-x 2 root sys 8192 Jan 5 12:44 back
-rwxr-xr-x 1 bin bin 655 Jan 5 12:51 evdel.sh
-rw-r--r-- 1 bin bin 382 Jan 5 12:54 list

Please check the permissions

That's pretty strange. It would make more sense to create a special user and not use one of the system UIDs.

>drwxr-xr-x 3 root sys 8192 Jan 5 12:54 /tmp/ActionNNM

This does not allow user bin to create the file events. root must create the file and chown it to bin:bin, then bin can write to it.
Or maybe you should have bin own the directory?

Hi:

> But when my application executes command as bin.

Do you mean that you want files created by your application to be owned by 'bin'?

If so, you can have the _group_ ownership set to 'bin' simply by setting the 'setgid' bit on the parent directory:

# chgrp bin /tmp/ActionNNM
# chmod g+s /tmp/ActionNNM

Now files createed in the directory will automatically have a group ownership of 'bin'. The file's owner will remain that of the effective uid of the process creating them, but this is a way to grant group visability.
