Description MikeM 2015-02-28 15:52:01 UTC
I just updated php5 via pkg.  I wanted to assure that pkgs dependent upon the php5 pkg were also updated.  So I read the man page for pkg-install and saw the option

     -R, --from-root
                When used with -f, reinstalls any packages that require the
                given package.


When I saw the mention of -f, I scratched my head, what was the man page trying to tell me.  Not liking to force anything, I ran the command without -f.  Here's what I saw:

# pkg install -R php5
Updating FreeBSD repository catalogue...
FreeBSD repository is up-to-date.
All repositories are up-to-date.
The following 8 packages will be affected (of 0 checked):

Installed packages to be UPGRADED:
        php5: 5.4.30 -> 5.4.37
        php5-gettext: 5.4.30 -> 5.4.37
        squirrelmail: 20140420 -> 20141107
        php5-session: 5.4.30 -> 5.4.37
        php5-xml: 5.4.30 -> 5.4.37
        php5-openssl: 5.4.30 -> 5.4.37
        php5-hash: 5.4.30 -> 5.4.37
        php5-mbstring: 5.4.30 -> 5.4.37

The process will require 14 KiB more space.
3 MiB to be downloaded.

Proceed with this action? [y/N]: y
[lots of installation output removed]


That is exactly what I wanted to happen, i.e., install php5 and install all the pkgs that are dependent upon it.

So now I wonder, what is the purpose of the -f option, if I the dependent packages were installed by just specifying -R.

Obviously, I'm confused and may not have read the intent of the -R documentation correctly.  Maybe it can be clarified to better explain what happens with and without the -f being specified?

If you also add the -f flag, it will reinstall packages that depend on PHP, even if there is not a newer version of that package.
Comment 2 MikeM 2015-03-21 16:50:58 UTC
Ahhh... that makes it clearer.  I'm not a wordsmith, but maybe verbiage for the -R option along the lines of:

------------------

reinstalls any out of date packages that require the given package. If you also add the -f flag, it will reinstall dependent packages even if there is not a newer version of that package.

------------------


In any case, thanks for your clarification.
