By examining the first, third and last (seventh) fields of the /etc/passwd file, determine the userid and login shell for your username, the user root, and the user nobody (yes, there is a system user with the username "nobody"). Create simple files in your home directory, called my.uid, my.shell, root.uid, root.shell, nobody.uid, and nobody.shell, which contain only the appropriate information on a single line.
For example, if the user nobody's login shell were /bin/bash, the following command would easily create the appropriate file.
[student@station student]$ echo /bin/bash > nobody.shell
[student@station student]$ cat nobody.shell
I don't know how to find the UID because when I opened the passwd file the first was root, but the third and seventh fields were completely different. Any help?
