How to Find a Directory in Linux
In Linux, directories are used to organize files and other directories within the filesystem. Every folder you see in a graphical interface is referred to as a directory in Linux.
There are several commands available to locate directories or files quickly from the command line.
Using the locate Command
The locate command searches a prebuilt database and is usually much faster than find.
locate directory_name
Example
locate apache2
This command displays all paths containing the name apache2.
Note: If locate does not return recent results, update the database using:
sudo updatedb
Using the find Command
The find command performs a real-time search in the filesystem and provides more filtering options.
Search for a Directory by Name
find / -type d -name "directory_name"
Example
find /home -type d -name "projects"
This command searches for a directory named projects under /home.
Display Detailed Information
To display detailed information about the matched directory:
find /home -type d -name "projects" -exec ls -lrth {} \;
Parameter Explanation
Search for Files by Name
To search for files instead of directories:
find /home -type f -name "filename.txt"
Case-Insensitive Search
If you're unsure about the exact capitalization:
find /home -type d -iname "projects"
The -iname option performs a case-insensitive search.
Conclusion
The locate and find commands are essential tools for navigating and managing Linux systems. Use locate for fast searches and find when you need more precise filtering and real-time results.
Quick Reference
# Locate a directory or file
locate directory_name
# Find a directory
find / -type d -name "directory_name"
# Find a file
find / -type f -name "filename"
# Case-insensitive search
find / -type d -iname "directory_name"
# Show detailed information
find / -type d -name "directory_name" -exec ls -lrth {} \;
Mastering these commands can save significant time when working with large Linux filesystems and server environments.
