If desired, you can work without a config file. If you already have a private key (nsec) then you can do simple commands like this:
E.g. fire-and-forget: send a message without a config file and forget everything after message has been sent:
nostr-commander-rs --nsec nsec1SomeStrangeString --add-relay "wss://some.relay.net/" --publish "some text"nostr-commander-rs --nsec $NSEC --add-relay "wss://some.relay.net/" --publish - < SOMETEXTFILE.txt
For more functionality or in order to create a new user you will want to work with a simple JSON credentials file.
You don't need to know any of this. This is just for the curious ones.
The default location of the config file is
$HOME/.local/share/nostr-commander-rs/credentials.json
or equivalent for other platforms.
The config file looks something like this. If you want to do some quick testing, you can copy and paste this config file to get going fast.

Welcome to "nostr-commander-rs", a Nostr CLI client. ─── On the first run use
--create-user to create a user. On further runs you can publish notes, send
private DM messages, etc. Alternatively, you can skip creating a user and do a
fire-and-forget publish like this: nostr-commander-rs --nsec
nsec1SomeStrangeString --add-relay "wss://some.relay.net/" --publish "test".
─── Have a look at the repo "https://github.com/8go/nostr-commander-rs/" and
see if you can contribute code to improve this tool. Safe!
Usage: nostr-commander-rs [OPTIONS]
Options:
--contribute
Please contribute
-v, --version [<CHECK>]
Print version number or check if a newer version exists on crates.io.
Details:: If used without an argument such as '--version' it will
print the version number. If 'check' is added ('--version check')
then the program connects to https://crates.io and gets the version
number of latest stable release. There is no "calling home" on every
run, only a "check crates.io" upon request. Your privacy is
protected. New release is neither downloaded, nor installed. It just
informs you
Possible values:
- check: Check if there is a newer version available
--usage
Prints a very short help summary. Details:: See also --help, --manual
and --readme
-h, --help
Prints short help displaying about one line per argument. Details::
See also --usage, --manual and --readme
--manual
Prints long help. Details:: This is like a man page. See also
--usage, --help and --readme
--readme
Prints README.md file, the documenation in Markdown. Details:: The
README.md file will be downloaded from Github. It is a Markdown file
and it is best viewed with a Markdown viewer. See also --usage,
--help and --manual
-d, --debug...
Overwrite the default log level. Details:: If not used, then the
default log level set with environment variable 'RUST_LOG' will be
used. If used, log level will be set to 'DEBUG' and debugging
information will be printed. '-d' is a shortcut for '--log-level
DEBUG'. If used once as in '-d' it will set and/or overwrite
--log-level to '--log-level debug'. If used twice as in '-d -d' it
will set and/or overwrite --log-level to '--log-level debug debug'.
And third or futher occurance of '-d' will be ignored. See also
'--log-level'. '-d' takes precedence over '--log-level'.
Additionally, have a look also at the option '--verbose'
--log-level <LOG_LEVEL>...
Set the log level by overwriting the default log level. Details:: If
not used, then the default log level set with environment variable
'RUST_LOG' will be used. If used with one value specified this value
is assigned to the log level of matrix-commander-rs. If used with two
values specified the first value is assigned to the log level of
matrix-commander-rs. The second value is asigned to the lower level
modules. More than two values should not be specified. --debug
overwrites -log-level. See also '--debug' and '--verbose'.
Alternatively you can use the RUST_LOG environment variable. An
example use of RUST_LOG is to use neither --log-level nor --debug,
and to set RUST_LOG="error,matrix_commander_rs=debug" which turns off
debugging on all lower level modules and turns debugging on only for
matrix-commander-rs
Possible values:
- none: None: not set, default
- error: Error: Indicates to print only errors
- warn: Warn: Indicates to print warnings and errors
- info: Info: Indicates to to print info, warn and errors
- debug: Debug: Indicates to to print debug and the rest
- trace: Trace: Indicates to to print everything
--verbose...
Set the verbosity level. Details:: If not used, then verbosity will
be set to low. If used once, verbosity will be high. If used more
than once, verbosity will be very high. Verbosity only affects the
debug information. So, if '--debug' is not used then '--verbose' will
be ignored
-c, --credentials <PATH_TO_FILE>
Specify a path to a file containing credentials. Details:: At
--create-user, information about the user, in particular its keys,
will be written to a credentials file. By default, this file is
"credentials.json". On further runs the credentials file is read to
permit acting as this established Nostr user. If this option is
provided, the provided path to a file will be used as credentials
file instead of the default one
[default:
/home/user/.local/share/nostr-commander-rs/credentials.json]
--create-user
Create a new user, i.e. a new key pair. Details:: This is usually
done only once at the beginning. If you ever want to wipe this user,
use '--delete-user' which deletes the key pair. Use this option in
combination with --name, --display_name, --about, --picture, --nip05,
and --nsec. Also highly recommended that you use this option together
with --add-relay. Add --nsec as option to import your existing nsec
private key, otherwise a new private key will be generated for you
--delete-user
Delete the current user, i.e. delete the current key pair. Details::
This will erase the key pair and other associated information like
user name, display name, etc. Afterwards one can create a new user
with '--create-user'
--name <USER_NAME>
Specify an optional user name. Details:: Used together with
'--create-user'. If this option is not set during '--create-user',
the information will be queried via the keyboard. If you want to set
it to empty and not be queried, provide an empty string ''
--display-name <DISPLAY_NAME>
Specify an optional display name. Details:: Used together with
'--create-user'. If this option is not set during '--create-user',
the information will be queried via the keyboard. If you want to set
it to empty and not be queried, provide an empty string ''
--about <DESCRIPTION>
Specify an optional description. Details:: Used together with
'--create-user'. If this option is not set during '--create-user',
the information will be queried via the keyboard. If you want to set
it to empty and not be queried, provide an empty string ''
--picture <URL>
Specify an optional picture or avatar. Details:: Used together with
'--create-user'. Provide a URL like 'https://example.com/avatar.png'.
If this option is not set during '--create-user', the information
will be queried via the keyboard. If you want to set it to empty and
not be queried, provide this URL 'none:'
--nip05 <NIP05_ID>
Specify an optional nip05 name. Details:: Used together with
'--create-user'. Provide a nip05 name like 'john@example.org'. If
this option is not set during '--create-user', the information will
be queried via the keyboard. If you want to set it to empty and not
be queried, provide an empty string ''
--nsec <PRIVATE_KEY>
Provide one private key. Details:: It has the form
'nsec1SomeStrangeString'. Alternatively you can use the Hex form of
the private key. Since this is your private key, you must protect it.
Don't put this key into a script, into Github, etc. If --nsec is
provided it will be used instead of the private key in the
credentials file. This argument is used e.g. in combination with
argument --publish. If you are using --nsec without a credentials
file most likely you want to also use -ad-relay argument. If --nsec
is used without --create-user then the credentials file will not be
modified or will not be created
-p, --publish [<NOTE>...]
Publish one or multiple notes. Details:: Notes data must not be
binary data, it must be text. Input piped via stdin can additionally
be specified with the special character '-'. If you want to feed a
text message into the program via a pipe, via stdin, then specify the
special character '-'. If your message is literally a single letter
'-' then use an escaped '\-' or a quoted "\-". Depending on your
shell, '-' might need to be escaped. If this is the case for your
shell, use the escaped '\-' instead of '-' and '\\-' instead of '\-'.
However, depending on which shell you are using and if you are
quoting with double quotes or with single quotes, you may have to add
backslashes to achieve the proper escape sequences. If you want to
read the message from the keyboard use '-' and do not pipe anything
into stdin, then a message will be requested and read from the
keyboard. Keyboard input is limited to one line. The stdin indicator
'-' may appear in any position, i.e. --publish 'start' '-' 'end' will
send 3 messages out of which the second one is read from stdin. The
stdin indicator '-' may appear only once overall in all arguments.
'-' reads everything that is in the pipe in one swoop and sends a
single message. Similar to '-', another shortcut character is '_'.
The special character '_' is used for streaming data via a pipe on
stdin. With '_' the stdin pipe is read line-by-line and each line is
treated as a separate message and sent right away. The program waits
for pipe input until the pipe is closed. E.g. Imagine a tool that
generates output sporadically 24x7. It can be piped, i.e. streamed,
into nostr-commander, and nostr-commander stays active, sending all
input instantly. If you want to send the literal letter '_' then
escape it and send '\_'. '_' can be used only once. And either '-' or
'_' can be used
--publish-pow [<NOTE>...]
Publish one or multiple notes with proof-of-work (POW). Details:: Use
also '--pow-difficulty' to specify difficulty. See also '--publish'
to see how shortcut characters '-' (pipe) and '_' (streamed pipe) are
handled. Disabled since version nostr-commander-rs 0.2.0 (nostr-sdk
0.21)
--dm [<KEY+MSGS>...]
Send one or multiple DMs to one given user. Details:: DM messages
will be encrypted and preserve privacy. The single recipient is
specified via its public key, a string in the form of 'npub1...', a
Hex key, or an alias from one of your contacts. The first argument is
the recipient, all further arguments are texts to be sent. E.g. '-dm
"npub1SomeStrangeNumbers" "First msg" "Second msg"' or '--dm joe "How
about pizza tonight?"'. See also '--publish' to see how shortcut
characters '-' (pipe) and '_' (streamed pipe) are handled
--send-channel-message [<HASH+MSGS>...]
Send one or multiple messages to one given channel. Details:: The
single destination channel is specified via its hash. See here for a
channel list: https://damus.io/channels/. The first argument is the
channel hash, all further arguments are texts to be sent. E.g.
'-send_channel_message "SomeChannelHash" "First msg" "Second msg"'.
See also '--publish' to see how shortcut characters '-' (pipe) and
'_' (streamed pipe) are handled. Optionally you can provide a relay
to be used for the channel send by using --relay. See --relay. If
--relay has values the first value from --relay will be used as
relay. If --relay is not used, then the first relay in the relay list
in the credentials configuration file will be used
--add-relay [<RELAY_URI>...]
Add one or multiple relays. Details:: A relay is specified via a URI
that looks like 'wss://some.relay.org'. You can find relays by
looking at https://github.com/aljazceru/awesome-nostr#instances.
Sampler relay registries are: https://nostr-registry.netlify.app/,
https://nostr.info/, or https://nostr.watch/. Examples:
"wss://relay.damus.io", "wss://nostr.openchain.fr". See also
'--proxy'
--proxy <PROXY>
Specify a proxy for relays. Details:: Used by --add-relay. Note that
this proxy will be applied to all of the relays specified with
--add-relay. If you have 3 relays with 3 different proxies, then run
the --add-relay command 3 times with 1 relay and 1 proxy each time.
An example proxy for the Tor network looks something like
"127.0.0.1:9050". If you want to use Tor via a proxy, to assure that
no information leaks you must use only one relay, i.e. the Tor relay.
If more then one relays are configured, data will be communicated to
and from all relays. A possible relay that you can use together with
a Tor proxy is
"ws://jgqaglhautb4k6e6i2g34jakxiemqp6z4wynlirltuukgkft2xuglmqd.onion"
--remove-relay [<RELAY_URI>...]
Remove one or multiple relays from local config file. Details:: See
--add-relay
--tag <TAG>
Specify one or multiple tags to attach to notes or DMs. Details:: Not
yet implemented
--show-metadata
Display current metadata. Details:: shows data in your config file
--change-metadata
Modify existing metadata of the user. Details:: Use this option in
combination with --name, --display_name, --about, --picture, and
--nip05
--pow-difficulty <DIFFICULTY>
Specify optional proof-of-work (POW) difficulty. Details:: Use with
'--publish_pow' to specify difficulty. If not specified the default
will be used
[default: 20]
--show-public-key
Show public key. Details:: Displays your own public key. You can
share this with your friends or the general public
--show-secret-key
Show private, secret key. Details:: Protect this key. Do not share
this with anyone
--whoami
Print the user name used by "nostr-commander-rs". Details:: One can
get this information also by looking at the credentials file or by
using --show-metadata
-o, --output <OUTPUT_FORMAT>
Select an output format. Details:: This option decides on how the
output is presented. Currently offered choices are: 'text', 'json',
'json-max', and 'json-spec'. Provide one of these choices. The
default is 'text'. If you want to use the default, then there is no
need to use this option. If you have chosen 'text', the output will
be formatted with the intention to be consumed by humans, i.e.
readable text. If you have chosen 'json', the output will be
formatted as JSON. The content of the JSON object matches the data
provided by the nostr-sdk SDK. In some occassions the output is
enhanced by having a few extra data items added for convenience. In
most cases the output will be processed by other programs rather than
read by humans. Option 'json-max' is practically the same as 'json',
but yet another additional field is added. In most cases the output
will be processed by other programs rather than read by humans.
Option 'json-spec' only prints information that adheres 1-to-1 to the
Nostr Specification. Currently this type is not supported. If no data
is available that corresponds exactly with the Nostr Specification,
no data will be printed
[default: text]
Possible values:
- text: Text: Indicates to print human readable text, default
- json: Json: Indicates to print output in Json format
- json-max: Json Max: Indicates to to print the maximum anount of
output in Json format
- json-spec: Json Spec: Indicates to to print output in Json format,
but only data that is according to Nostr Specifications
-l, --listen
Listen to events, notifications and messages. Details:: This option
listens to events and messages forever. To stop, type Control-C on
your keyboard. You want to listen if you want to get the event ids
for published notices. Subscriptions do not automatically turn
listening on. If you want to listen to your subscriptions, you must
use --listen
--add-contact
Add one or more contacts. Details:: Must be used in combination with
--alias, --key, --relay. If you want to add N new contacts, use
--add-contact and provide exactly N entries in each of the 3 extra
arguments. E.g. --add-contact --alias jane joe --key
npub1JanesPublicKey npub1JoesPublicKey --relay
"wss://janes.relay.org" "wss://joes.relay.org". Aliases must be
unique. Alias can be seen as a nickname
