|
||
|
|

|
||
|
|
The `whoami` command displays the username of the current effective user. In other words it just prints the username of the currently logged-in user when executed.
|
||
|
|
|
||
|
|
To display your effective user id just type `whoami` in your terminal:
|
||
|
|
|
||
|
|
```
|
||
|
|
manish@godsmack:~$ whoami
|
||
|
|
# Output:
|
||
|
|
manish

||
|
|
```

|
```

|
|
whoami [-OPTION]
|
||

|

|
|
|
