# The `dir` command
|
||
|
|
|
||
|
|
The `dir` command lists the contents of a directory(_the current directory by default_). **It differs from ls command in the format of listing the content**. By default, the dir command lists the files and folders in columns, sorted vertically and special characters are represented by backslash escape sequences.
|
||
|
|
|
||
|
|
### Syntax:
|
||
|
|
|
||
|
|
```[linux]
|
||
|
|
dir [OPTIONS] [FILE]
|
||
|
|
```
|
||
|
|
|
||
|
|
### Examples:
|
||
|
|
|
||
|
|
1. To list files in the current directory:
|
||
|
|
|
||
|
|
```[linux]
|
||
|
|
dir
|
||
|
|
```
|
||
|
|
|
||
|
|
2. To list even the hidden files in the current directory:
|
||
|
|
|
||
|
|
```[linux]
|
||
|
|
dir -a
|
||
|
|
```
|
||
|
|
|
||
|
|
3. To list the content with detailed information for each entry
|
||
|
|
|
||
|
|
```[linux]
|
||
|
|
dir -l
|
||
|
|
```
|
||
|
|
|
||
