install  -o root -g wheel -m 444 /s/portbuild/usr/ports/ports-mgmt/portmaster/wo                                                      rk/freebsd-portmaster-7359019/files/bash-completions  /s/portbuild/usr/ports/por                                                      ts-mgmt/portmaster/work/stage/usr/local/etc/bash_completion.d/
