This command combines the output of the "ls" command with the "dmenu" command using the pipe "|" operator.
The "ls" command lists the files and directories in the current working directory. The output of the "ls" command consists of a list of file and directory names.
The "|" (pipe) operator takes the output of the preceding command ("ls" in this case) and sends it as the input to the following command ("dmenu" in this case).
The "dmenu" command is a dynamic menu for X, which means it's a tool that allows you to select an item from a list of options displayed in a graphical interface. In this case, the output of the "ls" command is used as the input for the "dmenu" command, so the list of file and directory names appear in the "dmenu" interface for the user to select from.
Overall, this command lets you select a file or directory from the current working directory using a graphical menu presented by "dmenu".
