Redirect stdout and stderr

Redirect stdout and stderr

This is an always reoccuring issue for me, how to redirect the standard output and standard error into a file. Hence, a short overview as a reminder:

stdout -> File

program > file.txt

stderr -> File

program 2> file.txt

stdout AND stderr -> File

programm &> file.txt

stdout -> File AND stderr -> File

programm > file_stdout.txt 2> file_stderr.txt

stdout -> stderr

program 1>&2

stderr -> stdout

program 2>&1
