Modifying User Name and Password
When modifying the username, you will need to use replacement commands. The steps are as follows:
After entering the file in vi mode, use vi commands to make replacements.
:%s/Contents need to be replaced/contents replaced/g //Find and replace all matched items throughout the entire file.
For example: %s/foo/bar/g #Search for "foo" and replace it with "bar" throughout the entire file.
