When I install a port, I am often presented with a menu screen to select configuration options. If I'm going to install a really big package with lots of dependencies, that will be extremely inconvenient. Is there a make flag for accepting the default answers for all such prompts?
BATCH, described in ports(7), is what you're looking for:
# cd /usr/ports/sysutils/screen # export BATCH=yes # make rmconfig # make install clean (no configuration menu is displayed)
make rmconfig removes
OPTIONS config for this port, and you can use it to remove
OPTIONS which were previously saved when you configured and installed
screen(1) the first time.
OPTIONS are stored to directory which is specifed via
PORT_DB_DIR (defaults to
If you use bash,
BATCH can be set automatically every time you log in:
# echo 'export BATCH=yes' >> ~/.bash_profile
I think it's worth mentioning that you might not always want to do this. I seem to remember, for instance, needing to config emacs to add xft support. If you want to bypass the prompts for a single build,
make install clean BATCH=yes
will work as well.
This doesn't automatically accept defaults like you're asking, but I like the "make config-recursive" method which runs you through any options for the port you want as well as options for all dependencies. You don't have to change anything if you don't want to, but you go through all selection screens at once rather than whenever the building process arrives at them.
Once that's done, your "make install clean" should go pretty much unattended.
