File descriptor before a command

Welcome to Programming Tutorial official website. Today - we are going to cover how to solve / find the solution of this error File descriptor before a command on this date .

What does this mean? to have the file descriptor before a command line utility.


>&2 echo "Hey there! Something failed"

Afaik, it should have been at the end of a command line utility or a program.

echo "Hey there! Something failed" 1>&2

From the bash manual:

The following redirection operators may precede or appear anywhere within a simple command or may follow a command.
