How to List Only Directories in Linux
The ls command in Linux is used to list the files and directories in a directory. But if you wish to list directories only using ls command, what are the options?
We learn how to use command chaining (using pipes) to see what directories are present in a given directory.
In this tutorial, I will show you a number of ways to list directories only in Linux.
Listing directories using Wildcards
The simplest method is using wildcards. All the directories end in forward slash.
For the long listing, just add -l option.
Using -F option and grep
The -F options appends a trailing forward slash. So we can grep the directories only by ‘grep’ ing lines ending with a forward slash (/).
or for just the directory names, without -l option,
Using -l option and grep
In the long listing of ls i.e. ls -l , we can ‘grep’ the lines starting with d .
We can extract just the file names by printing only the last columns.
Using echo command
We can use echo command to list the entries trailing with forward slash (/).
Using printf
Similarly, printf can be used to highlight strings ending with forward slash (/).
Using find command
We can always find files based on their file types using find command:
The maxdepth option in the above command specifies that the search is to be performed in specified directory only. Otherwise, find command will find the directories recursively, by traversing each directory and their subdirectories. Also, in this command, the hidden directories are also shown. In all above methods that use ls command, the same can be achieved through -a option. For example,

Linux / UNIX List Just Directories Or Directory Names
You can use combination of ls command, find command, and grep command to list directory names only. You can use the find command too. In this quick tutorial you will learn how to list only directories in Linux or UNIX.
Tutorial details | |
---|---|
Difficulty level | Easy |
Root privileges | No |
Requirements | Linux, macOS, or Unix terminal |
Est. reading time | 5 minutes |
Display or list all directories in Unix
Type the following command:
$ ls -l | grep `^d’
$ ls -l | egrep `^d’
Or better try the following ls command only to list directories for the current directory:
$ ls -d */
Sample outputs:

Run the following ls command:
ls -d */

Linux Display or list only files
Type the following command to display list only files in Linux or Unix:
$ ls -l | egrep -v ‘^d’
$ ls -l | egrep -v ‘^d’
The grep command is used to searches input. It will filter out directories name by matching first character ‘ d ‘. To reverse effect i.e. just to display files you need to pass the -v option. It invert the sense of matching, to select non-matching lines.
Task: Create bash shell aliases to save time
You can create two aliases as follows to list only directories and files.
alias lf=»ls -l | egrep -v ‘^d'»
alias ldir=’ls -d */’
##alias ldir=»ls -l | egrep ‘^d'»
Put above two aliases in your bash shell startup file:
$ cd
$ vi .bash_profile
Append two lines:
alias lf=»ls -l | egrep -v ‘^d'»
alias ldir=’ls -d */’
#alias ldir=»ls -l | egrep ‘^d'»
Save and close the file in vim. Now just type lf – to list files. Again run ldir to list directories only:
$ cd /etc
$ ldir
Sample outputs:
List directory names only:
$ cd /etc
$ ldir
Sample outputs:
Use find command to list either files or directories on Linux
The find command can be used as follows to list all directories in /nas, enter:
Pass the -maxdepth 0 to limit listing to the starting-points i.e. the current working directory only:
find /path/to/dir -maxdepth 1 -type d
find . -maxdepth 1 -type d
find . -maxdepth 1 -type d -ls
Listing only directories using the find command in Linux
Putting it all together
Say you want to find all directories ending with .bak extension and delete it, run the following find command in the current directory:
find . -type d -iname «.bak» -delete
Verify it:
find . -type d -iname «.bak» -ls
The following shell script does two things for Apache/Nginx/Lighttpd Webroot such as /webroot/:
- First, finds all files and directories and set permission to read-only for security reasons.
- Second, it allows our web server to read files regardless of permission so that we don’t get an HTTP/403 error.
In other words, all write permissions are removed from Webroot. The server/web-app can only read files but can not alter any files or upload any files. It helps reduces attack surfaces provided that you configure the rest of the server and web application firewall correctly.

How to List Only Directories in Linux
By default, it lists all the contents, be it a file or a directory or a link or a named pipe.
But what if you want to list only the directories? How do you that?
Like anything in Linux, there are several ways to accomplish the same task. Listing only the directories is no different:
- ls -d */
- ls -l | grep ‘^d’
- find . -maxdepth 1 -type d
- echo */
- tree -d -L 1
Don’t worry. I’ll explain things in detail. Here’s the content of the directory I am going to use in the examples here:
Use ls command to list directories only
It is always good to do it with the familiar ls command because this is the command you use for displaying the content of a directory.
To list only the subdirectories, use the -d option with ls command like this:
Here’s the output it shows:
Why */ ? Because without it, ls -d will only return the directory name. The -d option list directories not its contents (which includes file, directories etc).
The */ is a pattern. With * , you list all the content (including contents of the subdirectories) and the / restricts the pattern to directories.
This picture depicts the difference pretty well.
You may combine it with long listing option -l and most other options:
If you do not want the trailing slash (/) at the end of the directory names, you can use the cut command to cut it out:
List only subdirectories in a specific directory
The above command works in the current directory. What if you are not in the same directory?
In this situation, you can use */ at the end of the path of the directory with ls -d :
Here’s an example where I move out of the Documents directory and then list only the directories inside Documents directory:
Did you notice that it doesn’t list the hidden directory? That’s one shortcoming of this method. You may use ls -d .*/ to display hidden directories, but it only displays hidden directories.
Use combination of ls and grep command
If you long list the contents, you can identify the directories because start with d .
You can use grep to filter the contents that start with d:
But this gives you a lot more fields than just the directory names:
Use find command to list only directories
Here’s how to use the find command to list only the subdirectories:
I hope you are familiar with the find command. I’ll explain it nonetheless.
With type d , you ask the find command to only look for directories.
With maxdepth 1 you ask the find command to keep the search at the current level only (and not go inside the subdirectories).
As you can see in the output above, it also shows the hidden directory.
Use tree command to list only directories
If your aim is to list only the directories, you may also use the tree command.
By default, the tree command gives you the complete directory structure. You can modify it to show only directories and only at the current level.
- d — look for directories only
- a — look for hidden files and directories as well
- i — remove the tree structure from the display
- L 1 — don’t go into the subdirectories
Here’s the output:
Using echo command for listing directories
The unlikely candidate? You’ll be surprised to know that echo command in Linux can also be used for displaying the contents of a directory. Try using echo * and see for yourself.
Similar to the ls command, you can also use the */ pattern to list only the directories in the current working directory.
Here’s the output which is identical to what you got with the ls -d command:
There could be more ways for listing only the directories, not files. In fact, the methods discussed here may have some ifs and buts based on what you are looking for.
If your aim is to just display the directories, most of the commands I discussed would work. If you want something more specific like only getting the directories name with slash etc, you’ll have to do some formatting on your own.
I hope you find this Linux tip helpful. Questions and suggestions are always welcome.

The Linux LS Command – How to List Files in a Directory + Option Flags
Since the creation of Unix in the 1970s, a lot of operating systems have used it as their foundation. Many of these operating systems failed, while others succeeded.
Linux is one of the most popular Unix based operating systems. It’s open source, and is used all over the world across many industries.
One amazing feature of the Linux operating system is the Command Line Interface (CLI) which allows users to interact with their computer from a shell. The Linux shell is a REPL (Read, Evaluate, Print, Loop) environment where users can enter a command and the shell runs it and returns a result.
The ls command is one of the many Linux commands that allow a user to list files or directories from the CLI.
In this article, we’ll go in depth on the ls command and some of the most important flags you’ll need day-to-day.
Prerequisites
- A computer with directories and files
- Have one of the Linux distros installed
- Basic knowledge of navigating around the CLI
- A smile on your face 🙂
The Linux ls Command
The ls command is used to list files or directories in Linux and other Unix-based operating systems.
Just like you navigate in your File explorer or Finder with a GUI, the ls command allows you to list all files or directories in the current directory by default, and further interact with them via the command line.
Launch your terminal and type ls to see this in action:
How to list Files in a Directory with Options
The ls command also accepts some flags (also known as options) which are additional information that changes how files or directories are listed in your terminal.
In other words, flags change how the ls command works:
PS: The word contents used in throughout the article refers to the files and directories being listed, not the actual contents of the files/directories ?
List files in the current working directory
Type the ls command to list the contents of the current working directory:
List files in another directory
Type the ls [directory path here] command to list the contents of another directory:
List files in the root directory
Type the ls / command to list the contents of the root directory:
List files in the parent directory
Type the ls .. command to list the contents of the parent directory one level above. Use ls ../.. for contents two levels above:
List files in the user’s home directory (/home/user)
command to list the contents in the users’s home directory:
List only directories
Type the ls -d */ command to list only directories:
List files with subdirectories
Type the ls * command to list the contents of the directory with it’s subdirectories:
List files recursively
Type the ls -R command to list all files and directories with their corresponding subdirectories down to the last file:
If you have a lot of files, this can take a very long time to complete as every single file in each directory will be printed out. You can instead specify a directory to run this command in, like so: ls Downloads -R
List files with their sizes
Type the ls -s command (the s is lowercase) to list files or directories with their sizes:
List files in long format
Type the ls -l command to list the contents of the directory in a table format with columns including:
- content permissions
- number of links to the content
- owner of the content
- group owner of the content
- size of the content in bytes
- last modified date / time of the content
- file or directory name
List files in long format with readable file sizes
Type the ls -lh command to list the files or directories in the same table format above, but with another column representing the size of each file/directory:
Note that sizes are listed in bytes (B), megabytes (MB), gigabytes (GB), or terabytes (TB) when the file or directory’s size is larger than 1024 bytes.
List files including hidden files
Type the ls -a command to list files or directories including hidden files or directories. In Linux, anything that begins with a . is considered a hidden file:
List files in long format including hidden files
Type the ls -l -a or ls -a -l or ls -la or ls -al command to list files or directories in a table format with extra information including hidden files or directories:
List files and sort by date and time
Type the ls -t command to list files or directories and sort by last modified date and time in descending order (biggest to smallest).
You can also add a -r flag to reverse the sorting order like so: ls -tr :
List files and sort by file size
Type the ls -S (the S is uppercase) command to list files or directories and sort by date or time in descending order (biggest to smallest).
You can also add a -r flag to reverse the sorting order like so: ls -Sr :
List files and output the result to a file
Type the ls > output.txt command to print the output of the preceding command into an output.txt file. You can use any of the flags discussed before like -la — the key point here is that the result will be outputted into a file and not logged to the command line.
Then you can use the file as you see fit, or log the contents of the file with cat output.txt :
.
Conclusion
There are tons of other commands and combinations you can explore to list out files and directories based on your needs. One thing to remember is the ability to combine multiple commands together at once.
Imagine you want to list a file in long format, including hidden files, and sort by file size. The command would be ls -alS , which is a combination of ls -l , ls -a , and ls -S .
If you forget any command or are unsure about what to do, you can run ls —help or man ls which will display a manual with all possible options for the ls command:
