Join Kevin Skoglund for an in-depth discussion in this video Creating directories, part of Unix for Mac OS X Users.
I want us to see how we can go back creating directories that we could put our files into.…Directories are essentially folders, but in Unix you are always going to…call them directories.…So start getting use to that terminology.…Instead of calling it a folder, call it a directory.…Making a directory is really simple.…We just say mkdir, space, and then the name of the directory we want.…So I am going to create one called testdir. Hit Return and it created it.…It didn't give me any output there. If I do ls-la you'll see that it created.…If we come down here at the very last entry, you can see there's a directory…because it has this d at the front and that differentiates it from just a…standard file which has a dash.…
Now if you were to try it again and create the same directory again, you'll get…an error letting you know that file exists.…It says File exists but it's actually letting us know that the directory exists…and then makes sure we don't accidentally overwrite something we don't mean to.…
