Understanding ln

What is ln?

ln (link) creates links to files.

Link types:

  • Symbolic links: Point to file path
  • Hard links: Direct file reference

Uses:

  • Shortcuts: Create file shortcuts
  • Organization: Organize files
  • Multiple access: Access file from multiple locations
  • System management: Manage system links

Symbolic Links

Create Symlink

Basic usage:

# Create symbolic link
ln -s target.txt link.txt

# -s = symbolic

Absolute vs Relative

Path types:

# Absolute path
ln -s /absolute/path/target.txt link.txt

# Relative path
ln -s ../target.txt link.txt

Hard Links

Create Hard Link

Basic usage:

# Create hard link
ln target.txt link.txt

# No -s flag = hard link

Hard Link Properties

Characteristics:

  • Same inode: Shares inode with original
  • No distinction: Original and link are equal
  • File system: Must be on same filesystem
  • Directory: Cannot hard link directories

Link Management

List Links

Find symlinks:

# Find symbolic links
find . -type l

# Or
ls -la | grep "^l"

Remove Links

Delete link:

# Remove link
rm link.txt

# Only removes link, not target

Troubleshooting

Broken Links

Fix broken symlinks:

# Find broken links
find . -type l ! -exec test -e {} \; -print

# Remove broken links
find . -type l ! -exec test -e {} \; -delete
