Lists of Basic Linux Commands for Bash

Linux

Linux has been commonly run almost everywhere in technology, such as your desktop, smartphone, router, web server, IoT and even in the stock market. If you are a web developer, mobile developer, software engineer, hardware engineer or other IT related person, learning Linux can help you have better understanding on collaboration and communication. This article records bunch of lists of basic Linux commands for the beginner needs.

Before we started, since Mac and Linux OS already has its own command editor. For Windows user, you can install one of Linux system, or one of desktop environment for Linux.

There also has a beta light version of “bash on Windows” for 64-bit Windows 10 user. Operating system installation guide can be found in HERE.

In bash on Windows, the current home directory can be found in:

C:\Users\YourUserName\AppData\Local\lxss\home

This directory is marked as a hidden system folder for a very good reason, so avoid creating and/or modifying files in this location using Windows tools and apps!

BASICS:

present current working directory
```
pwd
```
list all the files
```
ls
```
list all the files (include hidden files)
```
ls -a
```
list all the files with detail lists(permission, boolean, capacity, updated time)
```
ls -l
```
go on the document (Case sensitive, type tab in the middle to detect the folder name)
```
cd [folder name]
```
go to the root
```
cd /
```
go to home
```
cd ~
```
open default text editor (nano or vim). For vim advanced usage. Take a look at Vi Cheat Sheet.
```
nano [file name]
```
or
```
vi [file name]
```

read the first 10 lines in file
```
head [yourfile]
```
read the last 10 lines in file
```
tail [yourfile]
```
read the content in file
```
cat [yourfile]
```
Insert some text into file.
```
echo "Hello World!" >> [your file]
```
Insert some text into file and overwrite it. (use it carefully!)
```
echo "Hello World!" > [your file]
```

FILE OPERATIONS:

delete files
```
rm [file name]
```
remove directory
```
rm [file folder]
```
remove directory that has files (be careful!)
```
rm -R [file folder]
```
remove directory
```
rmdir [your folder name]
```
remove file
```
rm [your file name]
```
make directory
```
mkdir [your folder name]
```

move your file (like cut)

mv [file name] [file directory or file folder name]

rename your file
```
mv [file name] [different file name]
```

copy your file

cp [file name] [file directory or file folder name or different file name]

find/search your file by name

find [file directory] -name [file name]

find [where-to-look] [criteria] [what-to-do]

SUDO & USER PERMISSION:

If permission denied, try to add this before all commands. (run as super user administrator)
```
sudo
```
or
```
su
```
By default, the superuser (root) account is disabled and doesn’t have any password. You can create one by running:
```
sudo passwd root
```
add a new user
```
useradd -m -g users [user name]
```
remove home user folder
```
rm -rf /home/[user folder]
```
Give the folder store and all files and folders within the store folder all permissions. (Read -4, write -2, exec -1)
```
chmod 777 [your folder]
```

OTHERS:

Viewing all the configurations. (usually use for wifi and network interface)
```
ifconfig -a
```
clear your terminal interface
```
clear
```
terminal any process (be careful it might close your entire sever, like docker, your should use ctrl+p+q instead of below code)
```
^ C (ctrl+c)
```
