# The `rm` command
|
|
|
|
`rm` which stands for "remove" is a command used to remove *(delete)* specific files. It can also be used to remove directories by using the appropriate flag.
|
|
|
|
### Example:
|
|
```
|
|
rm filename.txt
|
|
```
|
|
### Syntax
|
|
```
|
|
rm [OPTION] [FILE|DIRECTORY]
|
|
```
|
|
|
|

|<center>-</center>|`-preserve-root[=all]`|do not remove `/` (default) <br>with 'all', reject any command line argument on a separate device from its parent|
|
|

|
|
|
|

|
***IMPORTANT NOTICE:***
|
|
1. `rm` doesn't remove directories by default, so use `-r`, `-R`, `--recursive` options to remove each listed directory, along with all of its contents.
|
|
2. To remove a file whose name starts with `-` such as `-foo`, use one of the following commands:
|
|
- `rm -- -foo`
|
|
- `rm ./-foo`
|
|
3. To ensure that files/directories being deleted are truly unrecoverable, consider using the `shred` command. |
