Title: Learn how to view the current path in Linux and code examples

In the Linux operating system, it is often necessary to view the current path in order to better understand Locate and manipulate files and directories. This article will introduce several methods to view the current path in Linux and provide specific code examples. I hope it can help readers become more proficient in performing path operations in the Linux environment.

1. Use the pwd command

pwdis the abbreviation of Print Working Directory and is used to display the full path of the current working directory. By entering thepwdcommand in the terminal, the current path can be displayed.

Sample code:

pwd

2. Use the echo command

pwdxcommand to display the working directory of the specified process. By passing the PID (Process ID) of the current process as a parameter to thepwdxcommand, the working directory of the current process can be displayed.

Sample code:

pwdx $(echo $$)

The above are several methods and code examples for viewing the current path in Linux. By mastering these methods, you will be able to perform path operations in the Linux system more conveniently and improve work efficiency. I hope that readers can become more comfortable managing files and directories in the Linux environment by applying these methods in practice.
