Solaris packaging - "build" class action script

Question

I tried to create a package with a build class action script but having problem with it. I am wondering if any one could give me hint on how to solve this problem? I tried to follow the example on the Solaris tutorial but it didn't work either.
In the prototype file, I have added: e build /etc/randomtable=etc/randomtable ? ? ?
In the pkginfo I have added: CLASSES=�none build�
Content of etc/randomtable in my build directory:
!install
# randomtable builder
if [ -f $PKG_INSTALL_ROOT/etc/randomtable ]; then
echo "/etc/randomtable is already in place.";
else
echo "# /etc/randomtable" > /etc/randomtable
echo "1121554 # first random number" >> /etc/randomtable
fi
!remove
# randomtable deconstructor
if [ -f $PKG_INSTALL_ROOT/etc/randomtable ]; then
# the file can be removed if it's unchanged
if [ egrep "first random number" /etc/randomtable ]; then
rm /etc/randomtable;
fi
fi
The error I got after running pkgadd on that package:
Modifying /etc/randomtable
/var/sadm/pkg/BPCttdb.2/save/build/etc/randomtable: !install: not found
/var/sadm/pkg/BPCttdb.2/save/build/etc/randomtable: !remove: not found
/var/sadm/pkg/BPCttdb.2/save/build/etc/randomtable: test: unknown operator first random number
pkgadd: ERROR: class action script did not complete successfully

Answer 1

I looked at the build script (/usr/sadm/install/scripts/i.build and r.build), and didn't see anything that parses the "!" directive. I'm not very familiar with build scripts, and the documentation is actually inherited from the original SVR4 documentation (not originating from Sun). But in looking at an example of a script that uses the build class, it expects the first argument to be either "install" or "remove" when called. So your example would look like this below. Note that my comment about the escaped comment can be ignored. It's surrounded by quotes, so is okay.
if [ $1 = install ] ; then
# randomtable builder
if [ -f $PKG_INSTALL_ROOT/etc/randomtable ]; then
echo "/etc/randomtable is already in place.";
else
echo "# /etc/randomtable" > /etc/randomtable
echo "1121554 # first random number" >> /etc/randomtable
fi
else
# randomtable deconstructor
if [ -f $PKG_INSTALL_ROOT/etc/randomtable ]; then
# the file can be removed if it's unchanged
if \[ egrep "first random number" $PKG_INSTALL_ROOT/etc/randomtable \]; then
rm /etc/randomtable;
fi
fi
So basically the SVR4 Applications Developers Guide incorrectly tries to use the "!install" and "!remove" commands.
