You might have come across these two words often STDOUT and STDERR and wondered what is this. So in this post, we are going to see what is STDOUT and STDERR in Linux and how to use them and how to echo to STDERR and how to use the output redirections like>&2and2>&1to redirect...
In a similar vein, when talking aboutstdin,stdout, andstderrit is convenient to trot out the accepted axiom that a process neither knows nor cares where its three standard streams are terminated. Should a process care whether its output is going to the terminal or being redirected into a file?

Python’s CLI uses threedata streams to handle shell commands: stdin for input data, stdout for output data, and stderr for error messages. Internally these are designated as 0, 1, and 2. The shell code now uses the dup2 command of the Python os module, which interacts with the operati...
Understanding the difference between stdout and stderr is important when you want to work with a program's output. For example, if you try to grep the output of the find command, the error messages are not filtered, because only the standard output is piped to grep.find / -name '*...
