Useful Linux commands for new users, get information about packages.

A Linux installation contains many useful manual pages that provide much useful information to help you find your way around your Linux file-system. The man hier command will load the hier(7) manual page that contains a full listing of all directories on your Linux system and what their role is in the file-system hierarchy. The man intro command is perfect for a new Linux user wanting to learn the command-line. It will give you a simple primer on the bash shell and useful commands that a Linux user will be using day to day.

The apropos command is used to search the manual pages on the system for a certain keyword. In this case we are searching for tutorials.

If you are needing to find out what a command does quickly, then the whatis command will help you. The output shows you what manual page is associated with the certain command.

localhost% whatis ls
ls (1p)              - list directory contents
ls (1)               - list directory contents

I am not sure what use this is but Linux has a quote command that will insert a word in quotes.

[jason@localhost ~]$ quote Supercalifragilisticexpialidocious
'Supercalifragilisticexpialidocious'

The shell-quote command allows you to pass text unmodified through a shell script. Install this by typing: this command on Fedora 25.

[root@localhost jason]# dnf install perl-String-ShellQuote-1.04-19.fc25.noarch

Then type this command to get information on this useful script.
