The fundamental UNIX commands necessary for development
- The command line is a tool for interacting with a computer using only text (also known as a text interface) rather than other methods like clicking and scrolling.
- If you press the Tab key while entering a file name or folder name, the rest of the name gets auto-completed.
- The directory that you're currently in, is called the current directory.
- In the file structure of a computer, there is a root directory at the very top. The root directory is represented by /.
#### Commands
##### File and Directory Structures
+ touch file_name.extension => Create new file
```sh
$ touch begin.txt
```
+ cat file_name => Displays the content of a file
```sh
$ cat begin.txt
```
` [` If you specify a file that does not exist using the cat command, you will get an error, as the command is invalid `]`
+ mkdir directory_name => Creates a new directory
```sh
$ mkdir code
```
+ cd directory_name => Moves to specified directory
```sh
$ cd html
```
` [` You'll get an error if you specify a directory that does not exist `] `
+ pwd (print working directory) => To know the directory you are currently working in
```sh
$ pwd
```
+ ls (Listing files) => Displays the directories and files that are direct children of the current directory
```sh
$ ls
```
+ `..` => Moves to the parent directory
```sh
$ cd ..
```
` [ ` If you execute cd without specifying a directory, you can move to what is called a home directory (represented by ~) `] `
##### Working with Files and Directories
+ mv directories/file_to_move/ destination_directory => Moves to directories/file
```sh
$ mv begin.txt html
```
+ mv old_file_name new_file_name => Renames a file
```sh
$ mv begin.txt end.txt
```
+ cp file_to_copy new_file_name. => To copy files
```sh
$ cp begin.txt copy.txt
```
+ cp -r directory_to_copy new_directory_name => Copy a directory ( r - Recursive copy)
```sh
$ cp -r code html
```
` [ ` If you try to copy a directory without adding the -r option, you will get an error `]`
+ rm file_to_remove => Removes a file
```sh
$ rm begin.txt
```
+ rm -r directory_to_remove => Removes a directory
```sh
$ rm -r code
```
#### Other Important Commands
+ man => Opens reference manual of a Linux operating system (help document)
```sh
$ man
```
+ history => Shows all the commands that you have used in the past for the current terminal session
