Linux directory and file names are “case sensitive” and can be up to 255 characters in length. To avoid using one of the many (approximately twenty) “illegal” characters, just use the letters a-z, A-Z and the numbers 0-9 for your Linux directory and file names.

Type in exit and press Enter to go back to working as a “regular” user. Example of Using the Linux sudo Command If you’re using Ubuntu or a variation, such as Kubuntu or Edubuntu, then run “sudo -i” (again, without the quotation marks) to start working at the command line prompt as the root user. You will need to type in the password of the first Linux user created on your system (during installation) and press Enter after running the sud...
