In a Linux hierarchy, users can use the mkdir command to create a new directory under any authorized directory, or they can use the CD command to convert from one directory to another. However, there is no prompt to tell the user which directory is currently in. To know the current directory, you can use the PWD command, which displays the entire path name. Name Print Working Directory Use Displays the path name of the working directory. Grammar

Stores pointer information pointing

Linux uses the PWD command to view the full path of the current working directory. Simply put, every time you operate on a terminal, you have a current working directory.When you are unsure of the current position, you use PWD to determine the exact location of the current directory within the file system. 1. Command format:PWD [Options] 2. Command function:View the full path to the current working direct

"Always back, you can reach the root directory3. "Current User home Directory" and "system root directory" are two different concepts. There are two ways to access the current user home directory. 1, CD, 2, CD ~4. CD-Returns the directory where it was before entering this directoryDaily one command:

1. PWD ModuleThe PWD module provides an operating interface for the UNIX password database,/etc/passwd, which contains local machine user account informationCommon operations are as follows:Pwd.getpwuid (UID): Returns sample information for the corresponding UIDExample:>>> pwd.getpwuid (0) pwd.struct_passwd (pw_name='root', pw_passwd ='x', Pw_uid=0, pw_gid=0, pw_gecos='root', pw_dir=' /root', pw_shel

In Linux, it is estimated that you often use the PWD command, which is to print the current working path, that isPRINTWOrkingDIrectroy, today we also come to the C language to implement this command.To implement this function, you need to use the following system call:# Include Char * getcwd (char * Buf, size_t size ); This system call returns the absolute path of the current working directory. The absolute path value is retained in the size Buf. If
