The logic that was tested in the previous commit is used to implement
the behaviour for unit-shell and other verbs without changes.
The compare-versions synopsis is shortened to "V1 [OP] V2" to make the
verb synopsis fit. Unusual capitalizaition of "Command" is changed to
"COMMAND" (it's a replace arg, not a fixed string), and some help
strings are adjusted. The order of options in --help is based on the
existing order in parse_argv(). The old order in --help was mostly
random. I think it might be good to figure out something more rational
here, but I'm leaving that as a separate step.
The urlification of dot(1) in the --help string is lost. It's hard to
do this with the help string being stored in a read-only section.
I think this is not worth the trouble to reimplement in the current
scheme.
The output of `systemd-analyze exit-status` changed in commit
e04ed6db6b, so that the exit-status class
for EXIT_SUCCESS and EXIT_FAILURE is "libc" instead of "glibc".
This commit makes the example output in the man-page match the actual
output again.
Related to https://github.com/systemd/systemd/pull/37641.
The name "transient settings" was used in docs/TRANSIENT-SETTINGS.md.
Using "setting" helps distinguish this from D-Bus "properties", which are
a much larger set, partially overlapping.
In the troff output, this doesn't seem to make any difference. But in the
html output, the whitespace is sometimes preserved, creating an additional
gap before the following content. Drop it everywhere to avoid this.
After 3b16e9f419, even the libraries are
documented in the man page, it is useful to mention which libraries are
checked in the command output.
Of course, the dependencies are kind of implementation detail, and may
be changed in the future version, but that's especially why I think
showing the library deps in the output is useful.
systemd-analyze is a debugging tool, and already shows many internal
states. I think there is nothing to prevent from showing the deps.
Prompted by #34477.
The verb s not really specific to credential management, it was always a
bit misplaced. Hence move it to systemd-analyze, where we already have
some general TPM related verbs such as "srk" and "pcrs"
Note, `systemd-analyze foo@.service --instance=hoge` is equivalent to
`systemd-analyze foo@hoge.service`. But, the option may be useful when
e.g. passing multiple template units that have restriction on their
instance name:
```
$ ls
template_aaa@.service template_bbb@.service template_ccc@.service
$ systemd-analyze ./template_* --instance=hoge
```
Without the option, we need to embed an instance name into each unit
name, so cannot use globs.
Prompted by #33681.

This adds support in `systemd-analyze capability` for decoding
capability masks (sets), e.g.:
```console
$ systemd-analyze capability --mask 0000000000003c00
NAME NUMBER
cap_net_bind_service 10
cap_net_broadcast 11
cap_net_admin 12
cap_net_raw 13
```
This is intended as a convenience tool for pretty-printing capability
values as found in e.g. `/proc/$PID/status`.
I find myself wanting to check this data with a quick command, and
browsing through /sys/ manually getting binary data sucks. Hence let's
do add a nice little analysis tool.
The command will refuse to write to a TTY, so give a strong hint
that redirecting to a file is recommended. This makes the synopsis,
man page text, and --help output consistent.
Also drop the space after the redirection operator everywhere.
Without `--root` or `--image`, the `security` command inspects all currently
loaded service units if no unit name is specified. But with `--root` or
`--image` with `--offline=true`, the `security` command exits silently if no
unit name is specified.
Also, fixed description of `--root` and `--image` in the man page, and added
missing `--unit` option to help text.
man:
- `verify` requires an argument
- `security` does not require an argument
- `fdstore` requires an argument
- `image-policy` requires an argument
`--help` text:
- missing `image-policy` command
- `cat-config` requires NAME or PATH
This is pretty low-level functionality, hence placed in systemd-analyze.
This is useful for working with systemd-cryptenroll --tpm2-device-key=,
as it acquires the SRK without requiring the full tpm2-tss tool set.
When looking at configuration, often a user wants to suppress the comments and
just look at the parts that actually configure something, roughly equivalent to
systemd-analyze cat-config … | rg -v '^(#|;|$)
This switch implements this natively, skipping lines that start with a comment
character or only contain whitespace.
For formats that have section headers, section headers are skipped, if only
followed by stuff that would be skipped. (The last section header is printed
when we're about to print some actual output.)
Note that the caller doesn't know if the format has headers or not. We do format
type detection in pretty-print.c. So the caller only specifies tldr=true|false, and
conf_files_cat() figures out if the format has headers and whether those should
be handled specially.
The comments that show the file name are always printed, even if all of the file
is suppressed.
This is a partial answer to the discussions in
https://github.com/systemd/systemd/pull/28919,
https://github.com/systemd/systemd/pull/29248. If the default config is shown in
config files, the user can conveniently use '--tldr' to show the relevant parts.
This tries to add information about when each option was added. It goes
back to version 183.
The version info is included from a separate file to allow generating it,
which would allow more control on the formatting of the final output.
Dump*() methods can take quite some time due to the amount of data to
serialize, so they can potentially stall the manager. Make them
privileged, as they are debugging tools anyway. Use a new 'dump'
capability for polkit, and the 'reload' capability for SELinux, as
that's also non-destructive but slow.
If the caller is not privileged, allow it but rate limited to 10 calls
every 10 minutes.
