Hi,

I am trying to install a package on solaris and one of the packaging scripts fail unexpectedly. There is a script called "checkinstall" which checks for the /opt space and aborts the installation if /opt is less than 100MB. In my case, even if /opt has enoguh space, the script fails.

This is my script

REQUIRED_SAPCE="100000"
AVAILABLE_SPACE=`df -k /opt | grep -v "avail" | awk '{print $4}'`
if [ "$AVAILABLE_SPACE" -lt "$REQUIRED_SPACE" ]
then
echo "Space available in /opt is ${AVAILABLE_SPACE}KB. ${REQUIRED_SPACE}KB required"
exit 1
fi

The baffling thing here is, we get an error message like this and the installation gets aborted.

Space available in /opt is 450000KB. 100000KB required.

So, obviously /opt has enough space. Then why this gets into the if loop unnecessarily. What could be the problem? Any ideas??

This works fine on our test machines and the issue is happening at one of the customer's machines.

Thanks in advance,
JStone.

I see a SAPCE vs SPACE. Your grep options should be grep -vi instead of grep -v

Try this.

Hi, Thanks for the reply. That was a typo by mistake. I iterate that I have installed the package successfully in our test enviroment so many times, I am just trying to figure out the reason for the failure on the customer's machine. Could that be something related to their machine settings?? By the way, what is the shell used during an install?

The shell used during an install will usually depend on the shebang that is present in the installation script.

Try the following

You should be able to see the commmands being carried out. That should help you. Unless you get access to the customer's box or ask the customer to run the above, I dont think there is a way to debug this.

Hi, Thanks for your suggestion. I will do that.

With AIX, the df command output shows the free space in the field 3 and the field header is'nt 'avail' but 'Free'.
The -P option (Displays information on the file system in POSIX portable format) gives output compatible with your script :
Jean-Pierre.

if the disk space for a single mount is determined, no to check for the word whether it is avail or free ...

either way the disk space with a -k option for a single mount would be displayed only in the following format

header
values for the single mount

now eliminate the first line that is process only the second line
