dmenu:tldr:f1ad8
This command is a combination of two separate commands, "ls" and "dmenu -b", with the "|" symbol acting as a pipe.
-
"ls" command: The "ls" command is a command-line utility in Unix-like operating systems, including Linux, that lists the files and directories in the current directory. It shows the names of all files and directories present in the folder where the command is executed.
-
"dmenu -b" command: "dmenu" is a dynamic menu for X that allows users to select options from a list. It creates a simple graphical menu that appears on top of other windows. The "-b" flag specifies that the menu should appear at the bottom of the screen.
The "|" symbol, known as a pipe, is used to redirect the output of one command (in this case, "ls") as the input to another command (in this case, "dmenu -b"). So, the output of the "ls" command will be passed as input to the "dmenu -b" command.
Combining these two commands with the pipe "|" results in the following action: The "ls" command will list the files and directories in the current directory, and this list of files will be passed as input to "dmenu -b". The "dmenu -b" command will then display a menu at the bottom of the screen, allowing the user to select from the listed files and directories.
Overall, this command combines the functionality of listing files and directories using "ls" and displaying them interactively using "dmenu" for easier selection in a graphical environment.
