How, from a Terminal, do I make a plain text file and a folder?
A directory can be made using the mkdir command. To make a child directory of the current directory it's simply:
This will create a directory (shown as a folder in Finder) named
A text file can be created in a few different ways. The simplest being the echo'ing of text and redirecting it in to a file like so:
echo This is some text > myfile.txt
This will create
myfile.txt and its contents will be the string
This is some text.
You can also use a command line text editor such as vim or emacs or nano to start a new text file. The following start a new text file and open them in the editor for each of the aforementioned editors:
vim myfile.txt emacs myfiles.txt nano myfile.txt
The nano text editor is probably the most new-user-friendly of those three choices.
