The t option shows TCP ports, u shows UDP ports, l shows listening ports, and n shows numerical addresses. Checking listening ports is a crucial step in troubleshooting network issues and identifying potential security risks."
## 19. What is the difference between a hard link and a soft link?
Why you might get asked this:
This tests your understanding of how files are linked in Linux filesystems. Knowing the differences is important for managing files and understanding directory structures. File systems are an important focus in linux administrator interview questions.
How to answer:
Explain that a hard link directly refers to the inode of a file, while a soft link is a pointer to the file path. Hard links cannot span filesystems, while soft links can.
Example answer:
"A hard link is essentially another name for the same file; it points directly to the same inode, which is the data structure that stores the file's metadata. A soft link, or symbolic link, is a pointer to the path of the original file. The key differences are that hard links can't cross filesystem boundaries and deleting the original file makes a soft link invalid, whereas a hard link will still allow you to access the file’s content. It’s something you only really understand once you've been asked linux administrator interview questions about it a few times!"
## 20. How do you assign the umask to a user permanently?
Why you might get asked this:
