Diving Into Bash
Introduction to Linux(Linux 4 n00bs)
Where am I?
At this point you should have your shell open and ready for input.
To find which directory you are in, type the following command.
pwd
This will output the directory that you are currently working in.
pwd stands for Print Working Directory.
Make a directory
Now, let's make a new directory!
Type the following command:
mkdir myNewDirectory
mkdir stands for Make Directories.
If you type ls, you will see the directory you just created.
ls
The ls command will list the contents of a directory.
Change Directory
To navigate between directories, you will need to use the Change Directory command. Take note of the output of pwd:
cd myNewDirectory pwd cd .. pwd cd / pwd cd /home/linux101 pwd ls -l
Notice that we've added a parameter to the end of the ls command. Passing parameters to a command can allow you to make that function behave differently.
If you compare the difference between ls and ls -l , you will see that ls -l gives you a more detailed view of this data (i.e. a long list.) You can discover more parameters of a command by looking at it's man page.
Yo dawg, take a look at the man page of the man command.
man man
A man page will typically give you a synopsis, description, examples of the command and what options(parameters) it will take.
cd / cd ~ pwd ls -l
chmod 777 myNewDirectory ls -l rmdir myNewDirectory
