What does the pwd command do in UNIX?
a) Prints the working directory
b) Changes the current directory
c) Displays process information
d) Prints file contents
Answer:
a) Prints the working directory
Explanation:
The pwd command in UNIX stands for “print working directory,” and it displays the absolute path of the current directory. This is useful when navigating through a complex directory structure and wanting to verify your current location in the file system.
When you use the pwd command, it shows the full path starting from the root directory. For example, if you are in the /home/user/documents directory, typing pwd will display /home/user/documents as the output.
Knowing the pwd command is essential for effective navigation in UNIX environments. It ensures that users always know their location in the file system, preventing confusion and errors when working with files and directories.
