How to find all directory in linux

How To Find Directory In Linux?

Linux provides different ways to find directories. Here we will look at how to find directories in a recursive way. In this tutorial, we will use commands like find and locate .

Find Directories and Files with find Command

Find command is a popular command to used a lot of different purposes like find file and directory, take a backup, copy files. Actually find do not have these abilities it just runs commands over search results like copy and backup.

Syntax

• `LOCATION` is the path or location we will search in
• `SEARCH_TERM` is the term which is the file or directory name we want to search
• `ACTION` is optional which can take actions like print, delete, rename in the search results

We will search for a directory bin in the root file system.

Find Command

Get Detailed Information about The Directories and Files

We can get detailed information about found directories by using -ls parameter for the find command.

Get Detailed Information

Here results will list the size of the directory permission of the directory, owner, last change date, etc.

Only List Directories

Up to now, we have searched for all files and directories. We can search for only directories by providing a type parameter with a directory specifier.

Only List Directories

Locate

Locate command is a non-interactive alternative to find command. Also, locate have restricted capabilities. The advantage of the locate command is that it is fast because locate use database to search. Manually a database for file and directories is created. Manually this database is updated. The search is done directly in this database. Database is located at /var/lib/mlocate/mlocate.db .

We will update our database to search with locate command. To update the locate database we need root privileges.

We will search for files and directories ends with /bin . In this example, we will use the regex option of the locate to specify the end of the line.

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.

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:

Linux list only directories using ls command

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/:

1. First, finds all files and directories and set permission to read-only for security reasons.
2. 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 Find a Directory On Linux Based System

I just switched from MS-Windows server admin to Debian Linux server system administration roles. I need to find a directory called project.images. I was also told that the locate command is the simplest and quickest way to find the locations of files and directories on Linux. But the locate command is not working out for me. How do I find project.images directory using command-line options only?

You need to use find command. It is used to locate files on Linux or Unix-like system. The locate command will search through a prebuilt database of files generated by updatedb.

The find command will search live file-system for files that match the search criteria.

How to find a directory on Linux

The find command syntax is:
find /where/to/look/up criteria action
find /dir/path/look/up criteria action
find /dir/path/look/up -name «dir-name-here»
find /dir/path/look/up -name «pattern»
find /dir/path/look/up -name «dir-name-here» -print
find /dir/path/look/up -name «dir-name-here»
find / -name «dir-name-here»
find / -type d -name «dir-name-here»
find / -type d -name «dir-name-here» 2>/dev/null

Linux find directory command

The following example will show all files in the current directory and all subdirectories:

Finding a directory

To find a directory called apt in / (root) file system, enter:

Alert: When searching / (root) file system, you need to run the find command as root user.

Find will show an error message for each directory/file on which you don’t have read permission

Why don’t you run updatedb and then locate and again you’ll have “simplest and quickest way to find the locations of files and directories on Linux”.

updatedb will update your database.

That only helps for semi-permanent files since it only checks periodically to update the updatedb database. For files that were created recently it will not be found.

Find is a great tool that i use a lot.
You could have talk about the -exec switch wich allows you to process the outpout. ie : find and delete all file in ./ that haven’t been modified since 90 day:

Anyway, great job on this website, keep it on!

I have to second that updatedb is the way to go for a novice linux user. No worries about syntax and whatnot. Its also very useful for when you need to do multiple scans since you only traverse the filesystem once.

In regards to -exec, you should be using -execdir when available due to some security implications… and the above rm -rf is somewhat dangerous since find by default traverses from the top down. Delete would be a much safer (and faster!!) operation than-exec rm.

I have to agree with your update, rm -Rf is maybe too dangerons to use for novice users.

I did not know -execdir wich seems to be very usefull.

Thank you for that update =)

Great article. so useful. since I don’t have root, I get very verbose “no permission” output that is useless and I have to find the actual location through all the muck. Is there a way to only print found paths? Thanks so much for this article!

All those “no permission” messages should be on stderr while the information you want is on stdout. Both stderr and stdout default to printing on the controlling terminal. Tacking “> stdoutfile” on the end of the command would separate them, leaving all the unwanted noise on the terminal and putting the good stuff in stdoutfile. It would make more sense to redirect stderr to /dev/null (throwing it away) and leaving the useful output on the controlling terminal, but that would require finding the instructions for redirecting stderr in the shell docs (again).

To avoid seeing stderr messages, just use something like this:
