inotifywait:tldr:18f90

This command is using the inotifywait tool to monitor a specific file for a specific event, and upon detecting that event, it will execute a given command.

Here is a breakdown of the command:

• inotifywait is a Linux command-line tool that can monitor file system events.
• --event is an option for inotifywait that allows you to specify the event to watch for. In this case, ${access} is a placeholder for a specific event variable. The actual event to monitor is not clear without knowing the value of ${access}.
• ${filename} is another placeholder for the name of the file you want to monitor.
• && is a shell operator that allows you to execute a command after the successful execution of the preceding command.
• ${command} is a placeholder for the command you want to execute when the specified event occurs.

So, in summary, this command uses inotifywait to watch for a specific event (${access}) on a given file (${filename}). When that event occurs, it will execute the ${command}. The actual behavior and functionality of this command depend on the values assigned to ${access}, ${filename}, and ${command}.
