LINUX learning procedure

LINUX-general technology-Linux technology and application information. For more information, see the following section. Original Author: Look up
Learning Overview: how to learn about LINUX: LINUX installation-> Virtual Machine installation-> File System mounting-> basic commands (File Operations, directory management, permission management, compression and decompression, disk management, system Management, kernel)

Linux video learning:
I. linux installation note: the disk is manually partitioned. It can be divided into three partitions (//,/root, and swap). LINUX can be compatible with WINDOWS file systems, the main features of LINUX are also mentioned in the previous section.

Ii. LINUX Virtual Machine installation: note that the memory should not exceed the host memory.

Iii. Notes after LINUX installation:
1) Identity Authentication: linux uses the shadow (SHADE) technology to make logon authentication more secure. A computer can be used for authentication.

2) load disk devices: MOUNT and UMOUT commands.

3) LINUX is case sensitive.

Iv. LINUX commands
SHELL is an interactive tool between users and the kernel.

Simplified operation method:
1) if the input command in SHELL is too long, because SHELL defaults to "Press ENTER" for execution, a backslash should be used when the command exceeds one line.

2) use the TABLE key to complete the file name, that is, if the file name is too long, sometimes it is unnecessary to finish.

3) use the abbreviated command alias, for example, alias good = 'CD/'. Then, enter "good" in the terminal to actually execute the cd/command. Use the unalias-a good command to delete the abbreviation.

LINUX commands must first understand the concept of environment variables:
Some commands without parameters are system environment variables. Such as (PWD, HISTORY, WHO, who am I, HOME.

LINUX commands are roughly divided:
File Management, disk management, file permission management, print management, user management, software management, startup management, and process management.
