rpcclient:tldr:3d3e7

The command "rpcclient $> queryuser ${select}" is used to query user information in a remote system using the RPC (Remote Procedure Call) protocol.

Here's a breakdown of the command:

• "rpcclient": It is a command-line tool used to interact with remote systems using RPC. It allows you to perform various operations and queries on remote systems.
• "$>": This symbol is a representation of the command prompt, indicating that the subsequent command should be executed in the rpcclient shell.
• "queryuser": It is a rpcclient command that is used to fetch information about a specific user or a list of users from the remote system.
• "${select}": Here, "${select}" represents a placeholder or a variable that needs to be replaced with an actual user or a list of users. You should replace it with the desired user or a comma-separated list of users you want to query.

For example, if you want to query information about the user "john", you should replace "${select}" with "john": rpcclient $> queryuser john

This will send a RPC query to the remote system, requesting user information for the user "john". The response from the remote system will be displayed in the rpcclient shell.
