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.

  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
		    DBBASE="`pkgparam SUNWsbcdB BASEDIR`/db"	# new DB software
	  DBBASE="`pkgparam SUNWspcdA BASEDIR`/db"	# old DB software
# Now look for the database file we will need for this installation
if [ $DBBASE/specUlatte ]; then
	  exit 0		# all OK
	  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
