BASH Shell Redirect Output and Errors To /dev/null

In the Bash shell, you can redirect the output and errors of a command to /dev/null to suppress them. /dev/null is a special file that discards all data written to it, so redirecting output or errors to /dev/null effectively discards them.

Here is an example of how you can redirect the output and errors of a command to /dev/null:

command > /dev/null 2>&1

The > /dev/null part of the command redirects the standard output (stdout) of the command to /dev/null, and the 2>&1 part redirects the standard error (stderr) to /dev/null.

You can also use the &> /dev/null syntax to redirect both stdout and stderr to /dev/null:

command &> /dev/null
