#
#
# Save mount point of floppy (INSPATH) and package name (PKGNAME)
#

INSPATH=/install/new
PKGNAME=`cat ${INSPATH}/usr/options/ksh.name`

echo "Installing the ${PKGNAME}."
echo "Copyright (c) 1984 AT&T Technologies, Inc."
echo "All Rights Reserved"


cd ${INSPATH}
echo "The following files are being installed:"
find . -print | cpio -pduvm /

#
# Give user closing message
#

chmod 1755 /bin/ksh
echo "Installation of the ${PKGNAME} is complete."
exit

UNINSTALL Example

# UNINSTALL a 3B2 Package
#
# Save mount point of floppy (INSPATH) and package name (PKGNAME)
#

INSPATH=/install/new
PKGNAME=`cat ${INSPATH}/usr/options/ksh.name`

#
# Remove the files found in the Rlist file from the hard disk.
#

echo "Removing the ${PKGNAME}."
echo "The following files are being removed:"
for i in `cat /install/install/Rlist`
do
    echo $i
    rm -f $i
done
echo "The ${PKGNAME} has been removed."

Rlist Example

Assuming the package name is foo, and it installs a single binary file in /usr/bin, then an example might be:

/usr/bin/foo
/usr/options/foo.name

new Directory

This directory holds all the files to be installed.

Note that there must be a file named /usr/options/<pkg>.name. This file identifies the package, and should contain a single line with a human-readable format, e.g. “AT&T Foo Shell”
