Problem

How to use the systemctl list-dependencies command: Show a unit's dependency tree in systemd. See also: systemctl list-units. More information: <https://www.freedesktop.org/software/systemd/man/latest/systemctl.html#list-dependencies%20UNIT%E2%80%A6>.

Solution

systemctl list-dependencies — Show a unit's dependency tree in systemd. See also: systemctl list-units. More information: <https://www.freedesktop.org/software/systemd/man/latest/systemctl.html#list-dependencies%20UNIT%E2%80%A6>.

Show the dependency tree of default.target:
systemctl list-dependencies


Show the dependency tree of a specific unit:
systemctl list-dependencies {{unit}}


Include all dependency types (not only Requires= and Wants=):
systemctl list-dependencies {{unit}} {{[-a|--all]}}


Limit the tree to a specific unit type:
systemctl list-dependencies {{unit}} {{[-t|--type]}} {{service|socket|target|mount|...}}


Reverse the direction to show units that depend on the specified unit:
systemctl list-dependencies {{unit}} --reverse


Print output without headers or footers (for scripts):
systemctl list-dependencies {{unit}} --no-legend
