Unix: Tutorial One

Tutorial One:

1. Listing all the files:

When you first login, your current working directory is your home directory.

To find out what is in your home directory, type:

ls

(list down all the contents/files at working directory)

ls -a

(list down all Hidden files or dot[.] files)


2. Making Directories:
For making directory/folders under home directory use below command:

mkdir filename

to see the directory you have created, tye:

ls

It will show your created directory/folder

3. Change Directory:
To change the current directory/folder and go to different/into created directory/folder, type:

cd filename

It will go into the directory

4. The . and .. directory:

cd .

You will stay where you are (the same directory)

cd ..

It will take you one directory up (back to home directory)

5. Pathnames:

To know where you are currently in file system, type:

pwd

It means 'print working directory). It will show you the full pathname

6. ~ (tilde) character:

It can be used to specify paths starting to your home directory so typing:

ls ~/homeDirectory

It will list down all the contents of directory (no matter where you are in file system)
