Bash - output redirection

Question

I am trying to redirect the error output to a file and terminal and throw away the standard output, but I cannot figure it out. Does anyone know how to do this?

Answer 1

myCommand 2>&1  1>/dev/null | tee /path/to/some/file.txt

STDOUT goes black in / dev / null

STDERR redirects to STDOUT

tee receives STDOUT and repeats its echo, and also writes it to a file

Answer 2

See this post. You will need to use the tee command to direct in several directions.
