Understand how to display the current path in Linux

In the Linux operating system, the current path refers to the current working directory of the user. Knowing the current path is very important for users to operate in a command line environment, because users need to know which directory they are in so that they can correctly locate and operate files. This article will introduce several methods to display the current path in Linux systems, and attach specific code examples.

Method 1: Use the pwd command

pwdThe command is the simplest and most direct way to view the current path in the Linux system. Users can directly enterpwdin the command line, and then press the Enter key, and the system will return the absolute path of the current path.

The sample code is as follows:

pwd

After executing the above command, the system will display the absolute path of the current path, such as/home/user/documents.

Method 2: Use echo combined with the PWD environment variable

The Linux system has a built-in environment variablePWD, which saves the directory path of the current user. Users can use theechocommand to display the value of this environment variable, which is the current path.

The sample code is as follows:

echo $PWD

After executing the above command, the system will output the absolute path of the current path, such as/home/user/documents.

Method 3: Use the cd command combined with the pwd command

Users can also view the current path through a series of command combinations, such as first using thecdcommand to switch to the desired path, and then use thepwdcommand to view the current path.

The sample code is as follows:

cd /home/user/documents pwd

After executing the above two commands, the system will display that the user has switched to the/home/user/documentsdirectory.

Method 4: Use the readlink command

readlinkThe command can be used to view the absolute path of the symbolic link. If there is a symbolic link in the current path, you can use thereadlinkcommand combined with thepwdcommand to display the absolute path of the current path.

The sample code is as follows:

readlink -f .

After executing the above command, the system will display the absolute path of the current path, such as/home/user/documents.

The above are several ways to display the current path in the Linux system. Users can choose the appropriate method to view the current path according to their own habits and needs. By mastering these methods, users can more conveniently operate files and perform other operations in the command line environment.
