Change uninstall script for OS X

Status: Declined
Moved to CAR database: CAR 467281

Hi,

 

I have some suggestions for the Uninstall.sh script that comes with the OS X installer:

 

1) Copy it on installation into the main LabView application folder so that users don't need to find (or redownload, in my case) the original installer just to remove a seven-day evaluation copy (grrrr....).

 

2) Lines 85-88 need modification. They read:

 

[from the file Uninstall.sh]

echo "pid=\$( ps -axww | grep nisvcloc | grep -v grep | awk '{print \$2}')"
echo "if [ \$pid ]; then"
echo "sudo kill -6 $pid"
echo "fi"

 

When I ran the script, the $pid was omitted in the screen output:

 

[from the screen output of Uninstall.sh]

pid=$( ps -axww | grep nisvcloc | grep -v grep | awk '{print $2}')

if [ $pid ]; then

sudo kill -6 

fi

 

It looks like the "$" should be changed to "\$' on line 87:

 

[Corrected line 87 for the file Uninstall.sh]

echo "sudo kill -6 \$pid"

 

3) For my OS, there is an error in both the documentation lines 85-88 and the associated code on lines 189-193: the process ID is associated with the first variable of the grep expression, not the second. The second variable returns the TTY for the process, which for nisvcloc is given as "??".

 

[from the file Uninstall.sh]

echo "Stopping the NI Service Locator..."
pid=$( ps -axww | grep nisvcloc | grep -v grep | awk '{print $2}')
if [ $pid ]; then
sudo kill -6 $pid
fi

 

[from the screen output of Uninstall.sh]

Stopping the NI Service Locator...

kill: illegal process id: ??

 

[Corrected line 190 for the file Uninstall.sh]

pid=$( ps -axww | grep nisvcloc | grep -v grep | awk '{print $1}')

 

[Corrected line 85 for the file Uninstall.sh]

echo "pid=\$( ps -axww | grep nisvcloc | grep -v grep | awk '{print \$1}')"

Continuing the previous post (sigh...):

 

4)  Put directions for uninstalling NI-VISA and NI-488.2 where you say they should be:

 

[from the screen output of Uninstall.sh]

How to remove NI-VISA: 

---------------------- 

Follow the directions located at:

/Applications/National Instruments/NI-VISA/Uninstall.txt

 

How to remove NI-488.2: 

----------------------- 

Follow the directions located at:

/Applications/National Instruments/NI-488.2/Uninstall.txt

 

Perhaps the uninstaller did all of this for me and deleted those files, but it doesn't look like it. The NI-488.2 and NI-VISA directories still have applications in them.

And finally....

 

It would be helpful to have a complete, easily accessible list of the OSX system files that are installed with LabView. Uninstall.sh left loads of LabView-related files in my /Library directory, and while I could identify most of them as part of LabView, I am wary of deleting ones that I'm not sure about.

 

For example, does anyone know if the following directory is part of LabView? A google search doesn't turn up anything conclusive.

 

/Library/Frameworks/lvxerces.framework

jsdodge, 

 

Thank you so much for trying out LabVIEW on Mac. In LabVIEW 2014 we are making several improvements to the Uninstall process. I've routed the issues you mentioned to our new Mac installer developer (who has been making terrific improvements).

 

Issue #1 has definitely been resolved in 2014 (see if you can get on the 2014 beta, ni.com/beta)

 

We'll evaluate the other issues and see if we can get improvements in 2014 for those.

 

I really appreaciate your feedback.
