Exercise 9: Making Empty Files (Touch, New-Item)

In this exercise you learn how to make an empty file using the touch (new-item on Windows) command.

Do This


$ cd temp
$ touch iamcool.txt
$ ls


> cd temp
> New-Item iamcool.txt -type file
> ls

    Directory: C:\Users\zed\temp

Mode                LastWriteTime     Length Name

You Learned This

You learned how to make an empty file. On Unix touch does this, and it also changes the times on the file. I rarely use it for anything other than making empty files. On Windows you don't have this command, so you learned how to use the New-Item command, which does the same thing but can also make new directories.

Do More

  • Unix: Make a directory, change to it, and then make a file in it. Then change one level up and run the rmdir command in this directory. You should get an error. Try to understand why you got this error.
  • Windows: Do the same thing, but you won't get an error. You'll get a prompt asking if you really want to remove the directory.
