Linux Fundamentals - Where do Process Data Streams Send Data by Default?

The video tutorial explains the concept of data streams in processes, specifically focusing on STD in, STD out, and STD error. It describes how these streams interact with the shell when commands like LS and mkdir are executed. The tutorial also covers how to redirect output from these streams to files and introduces the numeric IDs associated with each stream. Additionally, it discusses processes that accept input via STD in, highlighting that some commands do not utilize this stream.

What are the three data streams every process has?

• READ, WRITE, EXECUTE

• INPUT, OUTPUT, ERROR

• STDIN, STDOUT, STDERR

• IN, OUT, ERR

When you type 'ls' in the terminal, which data stream are you interacting with?

• STDOUT of the 'ls' process

• STDIN of the shell

• STDERR of the shell

• STDOUT of the shell

What happens to the output of the 'ls' command by default?

• It is sent to a file

• It is discarded

• It is redirected to the shell's STDOUT

• It is sent to the shell's STDERR

How can you change the default behavior of a process's STDOUT?

• By using a different shell

• By redirecting it to a file

• By using the 'mkdir' command

• By closing the terminal

Which of the following processes can accept input via STDIN?

• 'ls' command

• 'mkdir' command

• Processes that read from STDIN

• All shell commands
