Redirect output. More information: https://gnu.org/software/bash/manual/bash.html#Redirecting-Output.

• Redirect stdout to a file:

{{command}} > {{path/to/file}}

• Append to a file:

{{command}} >> {{path/to/file}}

• Redirect both stdout and stderr to a file:

{{command}} &> {{path/to/file}}

• Redirect stderr to /dev/null to keep the terminal output clean:

{{command}} 2> /dev/null

• Clear the file contents or create a new empty file:

> {{path/to/file}}

• Redirect stderr to stdout for piping them together:

{{command1}} 2>&1 | {{command2}}

• Open a persistent file descriptor:

exec {{3}}>{{path/to/file}}

• Write to a custom file descriptor:

{{echo text}} >&{{3}}
