This article mainly introduces how to write linux into the directory command, has a certain reference value, interested friends can refer to, I hope you read this article after a great harvest, the following let Xiaobian with everyone to understand.

Linux is a free-to-use and freely distributed UNIX-like operating system, is a POSIX-based multi-user, multitasking, multi-threaded and multi-CPU operating system, using Linux to run major Unix tools, applications and network protocols.

Linux directory entry command is "cd", the role of the command is to switch to the specified directory, syntax format is "cd [dirName]". The parameter "dirName" indicates the target directory to be switched, which can be an absolute path or a relative path; if the directory name is omitted, it is converted to the user's home directory.

This tutorial will operate on Red Hat Enterprise Linux 6.1, Dell G3 computers.

The linux directory entry command is "cd."

Linux cd command can be said to be the most basic command statement in Linux, other command statements to operate, are based on the use of cd command.

Therefore, to learn Linux common commands, we must first learn the use of cd command skills.

cd [dirName]

dirName: Target directory to switch.

2. Command function:

The dirName notation can be absolute or relative. If the directory name is omitted, it is changed to the user's home directory (i.e., the directory where login was first located).

Also,~ means home directory. It is the current location of the directory,.. It represents the directory one level above the current directory location.

Example 6: Return to parent directory

Example 7: Using the arguments from the previous command as cd arguments

[root@lianxi tmp]# cd !$ cd .. [root@lianxi /]#Thank you for reading this article carefully.
