I’ve written a script to automatically send email notifications to users who have access to a specific file or folder. However, I’m encountering issues retrieving the user details. Is it possible to achieve this through the backend or API?

What user details exactly? What issues exactly?

There are several occ commands to retrieve user information:

user@box:~# occ user:info --help
Description:
  show user info

Usage:
  user:info [options] [--] <user>

Arguments:
  user                   user to show

Options:
      --output[=OUTPUT]  Output format (plain, json or json_pretty, default is plain) [default: "plain"]
  -h, --help             Display help for the given command. When no command is given display help for the list command
  -q, --quiet            Do not output any message
  -V, --version          Display this application version
      --ansi|--no-ansi   Force (or disable --no-ansi) ANSI output
  -n, --no-interaction   Do not ask any interactive question
      --no-warnings      Skip global warnings, show command output only
  -v|vv|vvv, --verbose   Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

that one gives you various user informations about one specific user.

and

user@box:~# occ user:list --help
Description:
  list configured users

Usage:
  user:list [options]

Options:
  -l, --limit[=LIMIT]    Number of users to retrieve [default: "500"]
  -o, --offset[=OFFSET]  Offset for retrieving users [default: "0"]
      --output[=OUTPUT]  Output format (plain, json or json_pretty, default is plain) [default: "plain"]
  -i, --info             Show detailed info
  -h, --help             Display help for the given command. When no command is given display help for the list command
  -q, --quiet            Do not output any message
  -V, --version          Display this application version
      --ansi|--no-ansi   Force (or disable --no-ansi) ANSI output
  -n, --no-interaction   Do not ask any interactive question
      --no-warnings      Skip global warnings, show command output only
  -v|vv|vvv, --verbose   Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

that gives you the information of ALL users.

Here an example to get one big json object with all the information of all users:

user@box:~# occ user:list -i --output=json

… the json object can then be parsed with jq or other json tools and is an ideal source for further use in a script.

Much and good luck,
