This is a good book to get a tour of Linux/Unix operating system from the beginning. It is easy to read and is good for using look up all the commands, options along with tips that put those commands in context.
I will write down the summary and main points here to save and use later.
Introduction
Chapter 1: Getting Started with Unix
- Change password: passwd
- Listing directories and fliles: ls
- Changing directories: cd
- Moving up one level in the directory tree: cd .. (the current directory: .)
- Listing current directory: pwd
- Combining the ls and pwd commands to request the directory's contents and names
- Pipe symbol between the two commands, with or without a space on both sides of the pipe (|)
- Greater-than (>) indicates that the output of the program is to be redirected to the location (or filename) you specify after the symbol.
- Appending output to an existing file, adds to the end of an existing file.
- Use ? as a placeholder for one character or number, * as a placeholder for zero or more characters or numbers.
- Type more plus the name of the file you want to view. spacebar to see the next screen of information, B to move back through previous screens. Q to go back to the shell prompt.
- Displaying file contents: cat. The tac command is just like cat, but backward.
- cd /usr/bin where most installed programs are.
- ssh: type the name of any program you want to run; ssh, in this case, allows you to connect to another system.
- man: type followed by a command name to learn more about Unix programs.
