PWD - To check current working location/directory:
Before you create any File or Folder you need to know where you are currently present. To check current/present working location, you can use pwd command.
[user1@pc1 ~]$ pwd
/home/user1
[user1@pc1 ~]$
Where "/home/user" means you are currently available in user1 directory which is already created under /home directory.
mkdir - To create a directory/folder:
Syntax: mkdir <directory name>
[user1@pc1 ~]$ mkdir folder1
[user1@pc1 ~]$
In above example we created a folder/directory called "folder1" in current location.
cat - To create a file:
Though there are many ways to create file, here to begin with, in below example we are using cat command to create a file called file1.
Syntax: cat>filename
Note: after cat>filename press enter key and then type the content of file and when you are finished press ctrl+D (Press and hold ctrl key then press d) to save and exit.
[user1@pc1 ~]$ cat>file1
This is my first file.
[user1@pc1 ~]$
cat - To view/display the content of file: Syntax: cat <filename>
[user1@pc1 ~]$ cat file1
This is my first file.
[user1@pc1 ~]$
touch - To create an empty file:
[user1@pc1 ~]$ touch emptyFile
[user1@pc1 ~]$
Exercise:
1. Create a Folder called "Year".
2. Create a file called "Months" with names of every months.
[user1@pc1 ~]$ mkdir Year
[user1@pc1 ~]$ cat>Months
