How to handle new shells in Fedora packages
As this file can be edited by any people as default, we need to first determine if relevant lines are already existed. If existed already, then just echo relevant binary path to the file. Thus, here is an example of package with shell "foo" underneath /usr/bin:
%post
if [ "$1" = 1 ]; then
if [ ! -f %{_sysconfdir}/shells ] ; then
echo "%{_bindir}/foo" > %{_sysconfdir}/shells
else
grep -q "^%{_bindir}/foo$" %{_sysconfdir}/shells || echo "%{_bindir}/foo" >> %{_sysconfdir}/shells
fi
%postun
if [ "$1" = 0 ] && [ -f %{_sysconfdir}/shells ] ; then
sed -i '\!^%{_bindir}/foo$!d' %{_sysconfdir}/shells
fi
