== Deleting partitions ==

sh -c 'set -x; for i in `cd /dev/; ls *p*`; do echo gpart delete -i ${i##*p} ${i%p*}; done'
sh -c 'set -x; for i in `cd /dev/; ls ad*p*`; do echo gpart delete -i ${i##*p} ${i%p*}; done'
sh -c 'set -x; for i in `cd /dev/; ls da[0-9]* | grep -v s`; do gpart destroy -F $i; done'

== Loading the usr-tests.md.xz mfsroot at boot ==

load -t mfs_root /usr-tests.md.xz

== Getting FreeBSD ports to compile on FreeBSD 7 for pain and profit (directions worked with CURRENT @ ~r267851) ==

1. echo `'.include <bsd.own.mk>' > /usr/share/mk/src.opts.mk`.
2. Export the following variables:

   # Not sure how to get things to work with gcc; ran into -Wshadow problems
   # with libarchive and times(3), and gcc on the OS didn't support all of the
   # keywords that clang did (restrict for instance).

   export CC=clang FORCE_PKG_REGISTER=1 MK_ICONV=no MK_GCC=yes MK_GNUCXX=yes MK_SHARED_TOOLCHAIN=yes MK_TESTS=no MAKESYSPATH=/usr/share/mk NO_WARNING_PKG_INSTALL_EOL=1

3. Install the latest version of gcc/binutils.
4. Turn off spawn.h/posix_spawn support in lib/libarchive/freebsd_config.h.
5. Revert FreeBSD @ r252231 so sed will compile again.
6. Install `usr.bin/bmake lib/lzma lib/libarchive lib/libedit usr.bin/sed usr.bin/tar`
7. Remove RUN_DEPENDS for info in bsd.port.mk.
8. Install `devel/autoconf devel/automake devel/m4`

== Figuring out how many commits a FreeBSD developer has using git between two timeframes ==

Requirements:
- Commit notes for SVN revision numbers.
- The `upstream` remote be set [to github.com/freebsd/freebsd.git or an
  equivalent].

author=ngie
branches='master stable/10 stable/9'
start_date='2015-09-01'
end_date='2016-01-01' # This is inclusive

git fetch upstream;
for branch in master $branches; do
    # Commit notes
    num_commits=$(git log --author $author --pretty=format:"%ai %N" --after="$start_date" --before="$end_date" upstream/$branch | sed -e '/^[:space:]*$/d' | wc -l);
    printf "%24s: %4d\n" "$branch" "$num_commits";
