How to Gather File System Data

1. Make the directory containing your information files the current working directory.

2. Create a file named checkinstall with your favorite text editor.

3. Save your changes and quit the editor when you are done.

4. Complete one of the following tasks.

   • If you want to create additional installation scripts, skip to the next task, "How to Write Procedure Scripts".

   • If you have not created your prototype file, complete the procedure "How to Create a prototype File Using the pkgproto Command", and skip to Step 5.

   • If you have already created your prototype file, edit it and add an entry for the installation script you just created.

5. Build your package.

   See "How to Build a Package", if needed.

Where to Go Next

After you build the package, install it to confirm that it installs correctly and verify its integrity. Chapter 4, Verifying and Transferring a Package explains how to do this and provides step-by-step instructions on how to transfer your verified package to a distribution medium.

Example--Writing a checkinstall Script

This example checkinstall script checks to see if database software needed by the SUNWcadap package is installed.

# checkinstall script for SUNWcadap
#
# This confirms the existence of the required specU database
 
# First find which database package has been installed.
pkginfo -q SUNWspcdA	# try the older one
 
if [ $? -ne 0 ]; then
   pkginfo -q SUNWspcdB	# now the latest
 
	  if [ $? -ne 0 ]; then	# oops
		    echo "No database package can be found. Please install the"
		    echo "SpecU database package and try this installation again."
		    exit 3		# Suspend
	  else
		    DBBASE="`pkgparam SUNWsbcdB BASEDIR`/db"	# new DB software
	  fi
else
	  DBBASE="`pkgparam SUNWspcdA BASEDIR`/db"	# old DB software
fi
 
# Now look for the database file we will need for this installation
if [ $DBBASE/specUlatte ]; then
	  exit 0		# all OK
else
	  echo "No database file can be found. Please create the database"
	  echo "using your installed specU software and try this"
	  echo "installation again."
	  exit 3		# Suspend
fi
