How to Find Folders in Linux ?

Introduction

Searching for files and directories is a daily task for Linux users. Whether you’re cleaning up disk space, tracking down an old project, or exploring a new system, knowing how to find folders efficiently—and stop a command when needed—is essential.

In this post, we’ll walk through:

• How to find directories by name
• How to limit searches to avoid long waits
• How to safely stop a command that’s taking too long

Finding Directories by Name

The most common tool for searching in Linux is find.

To search for directories whose name contains projectX:

1

find ~ -type d -iname "*projectX*"

What this does:

• ~ searches only in your home directory (faster and safer)
• -type d limits results to directories
• -iname makes the search case-insensitive
• *projectX* matches any directory containing that word

Searching the Entire System (Use with Care)

If you really need to search everywhere:

1

find / -type d -iname "*projectX*" 2>/dev/null

The 2>/dev/null part hides permission errors, but be warned: this can take a long time on large systems.

Faster Searches with locate

If available, locate is much faster because it uses an index:

1

locate -i projectX

If it returns nothing, update the database:

1

sudo updatedb

How to Stop a Running Command

If a search is taking too long or producing too much output:

The universal solution

1

Ctrl + C

This immediately stops the command.

If the Command Won’t Stop

Suspend it:

1

Ctrl + Z

Then terminate it:

1

kill %1

Avoid Flooding Your Terminal

Pipe results to a pager:

1

find ~ -type d -iname "*projectX*" | less

Navigate with arrow keys and exit with:

1

q

Limit Search Depth

To prevent find from scanning endlessly:

1

find ~ -maxdepth 4 -type d -iname "*projectX*"

This limits how deep find will go into subdirectories.
