systemd-id128 - Generate and print sd-128 identifiers
systemd-id128 [OPTIONS...] new systemd-id128 [OPTIONS...] machine-id systemd-id128 [OPTIONS...] boot-id systemd-id128 [OPTIONS...] invocation-id
id128 may be used to conveniently print sd-id128(3) UUIDs. What identifier is printed depends on the specific verb. With new, a new random identifier will be generated. With machine-id, the identifier of the current machine will be printed. See machine-id(5). With boot-id, the identifier of the current boot will be printed. Both machine-id and boot-id may be combined with the --app-specific=app-id switch to generate application-specific IDs. See sd_id128_get_machine(3) for the discussion when this is useful. With invocation-id, the identifier of the current service invocation will be printed. This is available in systemd services. See systemd.exec(5).
The following options are understood: -p, --pretty Generate output as programming language snippets. -a app-id, --app-specific=app-id With this option, an identifier that is the result of hashing the application identifier app-id and the machine identifier will be printed. The app-id argument must be a valid sd-id128 string identifying the application. -h, --help Print a short help text and exit. --version Print a short version string and exit.
On success, 0 is returned, a non-zero failure code otherwise.
