Off the top of my head:

 git clone --depth=1 git://git.sv.gnu.org/coreutils.git
 cd coreutils
 ./bootstrap && ./configure --quiet && make -j$(nproc)
 git checkout -b my-branch
 vim src/ls.c
 make
 # make install # to install to /usr/local/... by default
 # (which is adjustable with ./configure options).
