Description: `Add a new user to the ntfy user database.
|
|
|
|
A user can be either a regular user, or an admin. A regular user has no read or write access (unless
|
|
granted otherwise by the auth-default-access setting). An admin user has read and write access to all
|
|
topics.
|
|
|
|
Examples:
|
|
ntfy user add phil # Add regular user phil
|
|
ntfy user add --role=admin phil # Add admin user phil
|
|
`,

Description: `Change the password for the given user.
|
|
|
|
The new password will be read from STDIN, and it'll be confirmed by typing
|
|
it twice.
|
|
|
|
Example:
|
|
ntfy user change-pass phil
|
|
`,

Usage: "Changes the role of a user",

UsageText: "ntfy user change-role USERNAME ROLE",
|
|
Before: inheritRootReaderFunc,
|
|
Action: execUserChangeRole,
|
|
Description: `Change the role for the given user to admin or user.
|
|
|
|
This command can be used to change the role of a user either from a regular user
|
|
to an admin user, or the other way around:
|
|
|
|
- admin: an admin has read/write access to all topics
|
|
- user: a regular user only has access to what was explicitly granted via 'ntfy access'
|
|
|
|
When changing the role of a user to "admin", all access control entries for that
|
|
user are removed, since they are no longer necessary.
|
|
|
|
Example:
|
|
ntfy user change-role phil admin # Make user phil an admin
|
|
ntfy user change-role phil user # Remove admin role from user phil
|
|
`,
|
|
},
|
|
{
|
|
Name: "list",
|
|
Aliases: []string{"l"},
|
|
Usage: "Shows a list of users",
|
|
Before: inheritRootReaderFunc,
|
|
Action: execUserList,
|
|
},
|
|
},
|
|
Description: `Manage users of the ntfy server.
|
|
|
|
This is a server-only command. It directly manages the user.db as defined in the server config
|
|
file server.yml. The command only works if 'auth-file' is properly defined. Please also refer
|
|
to the related command 'ntfy access'.
|
|
|
|
The command allows you to add/remove/change users in the ntfy user database, as well as change
|
|
passwords or roles.
|
|
|
|
Examples:
|
|
ntfy user list # Shows list of users
|
|
ntfy user add phil # Add regular user phil
|
|
ntfy user add --role=admin phil # Add admin user phil
|
|
ntfy user del phil # Delete user phil
|
|
ntfy user change-pass phil # Change password for user phil
|
|
ntfy user change-role phil admin # Make user phil an admin
|
|
