How to specify the stderr file in the bash script? [duplicate]

Question

I have a simple bash script:

#!/bin/bash

Some bash code....

And when starting it with:

./myscript.sh

I would like to redirect the error into error.err file, and I would like to specify the name of this file (here: error.err) inside myscript.sh file.

(so I would like to avoid doing: ./myscript.sh 2>error.err)

Is it possible

Thanks a lot

The linked question covers stdout as well, but its answers are trivial to adapt to ignore stdout and redirect stderr only. — Charles Duffy

Just prepend the following line to the script

exec 2>error.err

Read the part "so I would like to avoid doing........"

@ailauli69 you put it inside the script as a line of code. An empty exec changes the destination of your file descriptors for the currently running process.
