Simply run the following command from the bash terminal prompt, which filters the file listing to only show folders:
ls -l | grep ^d
Since typing that whole command every time you want to show a list of directories might get a little tiring, you can use the alias feature to assign it to something you can more easily remember:alias lsd="ls -l | grep ^d"
Now when you type "lsd" at the prompt, you will see a list containing only the directories, which can be very useful when you are trying to navigate through a messy set of folders.For more on using the command prompt, check out our top 10 command line tools, get your own drop-down Yakuake terminal, or learn to use cron from the command line.
