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
