The command "${ls} | wl-copy" is a combination of two separate commands, using the pipe "|" symbol to connect them.

1. ${ls}: This is using the command "ls" to list the contents of the current directory. The "${}" syntax is often used to interpret the output of a command, and in this case, it indicates that the output of the "ls" command will be used as input for the next command.

2. | (pipe symbol): This is used to redirect the output of the previous command to the input of the next command. It creates a pipeline between the commands, allowing data to flow from one to the other.

3. wl-copy: This is a command used in the Wayland display server system. It copies the input provided to it and saves it in the clipboard.

Putting it all together, the command "${ls} | wl-copy" lists the contents of the current directory using the "ls" command, and then it pipes that output to the "wl-copy" command, which copies the output and saves it in the clipboard. So, essentially, this command copies the list of files and directories in the current directory to the clipboard.
