How to redirect both stdout and stderr to a file

I am running a bash script that creates a log file for the execution of the command

I use the following

Command1 >> log_file
Command2 >> log_file

This only sends the standard output and not the standard error which appears on the terminal.

Solution

  • If you want to log to the same file:

    command1 >> log_file 2>&1

    If you want different files:

    command1 >> log_file 2>> err_file
