We are now at the end of this lesson and at the end of these lessons where we learn so many commands.
I like giving you a command overview. So what have we seen? We talked about Whoami, which is showing your current username.
LS can be used to list files and contents of directories, IPA is showing
your IP address and CAT or allows you to read a text file.
PASSWD allows you to set your password, and even if you
have super user privileges, you can change passwords for other users.
Touch is awesome if you want to verify your writability. So are you allowed to
write in a specific location or not? Use Touch to create an empty file.
PWD is printing the working directory and MAN is the
system that provides help for all of these Linux commands.
Then there is apropos, which is equivalent to man K. Use it. If you are looking for a
man page and you don't know which one to use, then just use apropos followed by a keyword.
MANDB is the administrator command that allows you to generate the mandb.
And finally the info command is an alternative if MAN indicates that the information is not maintained here. Every
now and then you might have to check it up in info, but fortunately current Linux distributions often have
enough documentation already in the man page, which means that you don't have to use info that often.
