There are some tricks we have not mentioned yet about the
pkg- files that
come in handy sometimes.*
To display a message when the package is installed,
place the message in pkg-message. This
capability is often useful to display additional installation
steps to be taken after a pkg install or to
display licensing information.
When some lines about the build-time knobs or warnings
have to be displayed, use ECHO_MSG.
pkg-message is only for
post-installation steps. Likewise, the distinction between
ECHO_MSG is for printing
informational text to the screen and ECHO_CMD
is for
command pipelining:
update-etc-shells:
@${ECHO_MSG} "updating /etc/shells"
@${CP} /etc/shells /etc/shells.bak
@( ${GREP} -v ${PREFIX}/bin/bash /etc/shells.bak; \
${ECHO_CMD} ${PREFIX}/bin/bash) >/etc/shells
@${RM} /etc/shells.bakDo not add an entry for pkg-message
in pkg-plist.
