transmission-remote:tldr:327d6

This command is using the 'transmission-remote' tool to interact with a Transmission BitTorrent client running on a remote host. Here is a breakdown of the command:

1. 'transmission-remote': This is the command to run the 'transmission-remote' tool.

2. '${hostname}': This is a variable representing the hostname or IP address of the remote machine where the Transmission client is running. Its value should be substituted before executing the command.

3. '-t "${1,2}"': This part selects multiple torrent files to perform actions on. "${1,2}" is a placeholder for the values of parameters one and two passed when executing the command. It means the command will operate on torrents numbered 1 and 2.

4. '--start': This flag is used to start the selected torrents (specified by '-t "${1,2}"').

5. '-t ${3}': This selects another torrent file, identified by the value passed as the third parameter, to perform an action on.

6. '--stop': This flag is used to stop the selected torrent specified by '-t ${3}'.

In summary, the command starts torrents 1 and 2 and then stops the torrent specified by the third parameter. The specific values for ${1}, ${2}, and ${3} need to be provided before executing the command.
