The command "tail $(svcs -L apache)" is composed of two parts: "svcs -L apache" and "tail".

1. "svcs -L apache": This command lists the state of the "apache" service using the "svcs" command with the "-L" flag. The "svcs" command is a Solaris command that displays the status of system services. By specifying "apache" after the "-L" flag, it filters and only shows information about the "apache" service.

2. "tail": This command is used to display the last few lines of a file or output. By default, it displays the last ten lines.

Putting it all together, the "$(svcs -L apache)" part is a command substitution, which means the output of the "svcs -L apache" command will be passed as an argument to the "tail" command. So, it will output the last few lines from the status of the "apache" service.
