How do I exclude a directory when using find in Linux?

To exclude a directory when using the find command in Linux, use the -prune option to prevent find from descending into specific directories. Here’s how to do it:

Basic Syntax

find /path/to/search \( -name "directory_to_exclude" \) -prune -o [options/actions]
  • -name "directory_to_exclude": Matches the directory you want to skip.
  • -prune: Tells find not to traverse into the matched directory.
  • -o: Logical “OR” operator to combine conditions.

Examples

1. Exclude a Single Directory

Exclude the node_modules directory when searching for files:

find . -name "node_modules" -prune -o -print

2. Exclude Multiple Directories

Exclude both logs and cache directories:

find /var \( -name "logs" -o -name "cache" \) -prune -o -print

3. Search for Files While Excluding a Directory

Find all .txt files but skip the backup directory:

find /home -name "backup" -prune -o -name "*.txt" -print

4. Exclude a Directory by Path

Exclude an absolute path like /home/user/temp:

find /home -path "/home/user/temp" -prune -o -print

5. Combine with Other Actions

Delete all files except those in the protected directory:

find . -name "protected" -prune -o -type f -delete

Key Notes

  • Grouping Conditions: Use \( ... \) to group multiple exclusion conditions.
  • Case Insensitivity: Use -iname instead of -name for case-insensitive matching.
  • Wildcards: Use wildcards (e.g., *.log) to exclude patterns.

Alternative: Use -not -path (Less Efficient)

This checks every file path, which is slower than -prune:

find . -not -path "./exclude_dir/*" -print

Summary

ScenarioCommand
Exclude one directoryfind . -name "dir" -prune -o -print
Exclude multiple directoriesfind . \( -name "dir1" -o -name "dir2" \) -prune -o -print
Exclude by pathfind . -path "./dir/*" -prune -o -print
Case-insensitive exclusionfind . -iname "DirName" -prune -o -print

Use -prune to efficiently skip directories and avoid unnecessary traversal!
