Hi,
On our systems the /bin/ksh link is created when ksh is installed. It uses the
alternatives system:
$ rpm -q --scripts ksh
postinstall scriptlet (using /bin/sh):
if [ ! -f /etc/shells ]; then
echo "/bin/ksh" > /etc/shells
else
if ! grep -q '^/bin/ksh$' /etc/shells ; then
echo "/bin/ksh" >> /etc/shells
fi
fi
/usr/sbin/alternatives --install /bin/ksh ksh \
/bin/ksh93 50 \
--slave /usr/share/man/man1/ksh.1.gz ksh-man \
/usr/share/man/man1/ksh93.1.gz
#if not symlink we are updating ksh where there was no alternatives before
#so replace with symlink and set alternatives
if [ ! -L /bin/ksh ]; then
/usr/sbin/alternatives --auto ksh
ln -sf /etc/alternatives/ksh /bin/ksh
ln -sf /etc/alternatives/ksh-man /usr/share/man/man1/ksh.1.gz
fi
preuninstall scriptlet (using /bin/sh):
if [ $1 = 0 ]; then
/usr/sbin/alternatives --remove ksh /bin/ksh93
fi
postuninstall scriptlet (using /bin/sh):
if [ ! -f /bin/ksh ]; then
sed -i '/^\/bin\/ksh$/ d' /etc/shells
fi
verify scriptlet:
echo -n "Looking for ksh in /etc/shells... "
if ! grep '^/bin/ksh$' /etc/shells > /dev/null; then
echo "missing"
echo "ksh missing from /etc/shells" >&2
else
echo "found"
fi
