This page outlines stuff I stumble upon, remember that I actually know this, but still not use in my daily practice and forgot about. Shame on me, because I should use this!
Use the right tool for the work
Often there is a simple tool that does exactly what you want. Consider this piece of a bash script:
mkdir /etc/systemd/system/podman.service.d chmod 0755 /etc/systemd/system/podman.service.d chown root:root /etc/systemd/system/podman.service.d cp podman.conf /etc/systemd/system/podman.service.d/ chmod 0644 /etc/systemd/system/podman.service.d/podman.conf chown root:root /etc/systemd/system/podman.service.d/podman.conf
The above works perfectly well. Is it readable? Yes, probably. Still, there is a
tool for this. Not often used in the wild, but mandatory for package maintainers,
install. The sole purpose of this is tool is to install files with the
correct mode and ownership in a single command. The above using
then look like:
install -o root -g root -m 0755 -d /etc/systemd/system/podman.service.d install -o root -g root -m 0644 podman.conf /etc/systemd/system/podman.service.d
More elegant, isn't it? So, go and use
install from now on!
