|
- 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}}`
