So if you build your own packages (rpm/dpkg/other), you might have your own repository of packages for your systems. And if you want to tell your hosts to update just the one repository, you might be looking for a solution. A user on Ask Ubuntu had a fantastic answer for Ubuntu/debian flavor: http://askubuntu.com/questions/65245/apt-get-update-only-for-a-specific- repository/197532#197532. For those of you who don't want to click through, here is a summary of the entries, collapsed down to just one file (which might not be the best solution, but it works). Add these lines to ~/.bashrc: update-repo() { for source in "$@"; do sudo apt-get update -o Dir::Etc::sourcelist="sources.list.d/${source}" \ -o Dir::Etc::sourceparts="-" -o APT::Get::List-Cleanup="0" done } _ppa_lists(){ local cur _init_completion || return COMPREPLY=( $( find /etc/apt/sources.list.d/ -name "*$cur*.list" \ -exec basename {} \; 2> /dev/null ) ) return 0 } && complete -F _ppa_lists update-repo With rpm-based systems like RHEL/CentOS/Fedora, you are using yum or dnf. Here's my dnf implementation: _command_dnf=yum which dnf 1>/dev/null 2>&1 && _command_dnf="$( which dnf 2>/dev/null )" # update-repo command for dnf update just one repository update-repo() { case "${_command_dnf}" in *dnf) for source in "$@"; do sudo "${_command_dnf}" check-update -q --refresh --disablerepo=* --enablerepo="${source}" done ;; *yum) for source in "$@"; do sudo "${_command_dnf}" clean metadata -q --disablerepo=* --enablerepo="${source}" -q; yum check-update -q --disablerepo=* --enablerepo="${source}" done ;; esac } # autocomplete for update-repo _repo_lists() { local cur _init_completion || return COMPREPLY=( $( grep -hoiE -- "^\[.*\]" /etc/yum.repos.d/* | tr -d '[]' | grep -E "^${2:-.*}" ) ) return 0 } && complete -F _repo_lists -o filenames update-repo The functions whose names start with an underscore are the auto-complete commands. Who doesn't like a good tab auto-completion? Now that I learned how to do my own bash- completion, I'll be doing it a lot more!
