readlink Basics

Read Link Target

Basic usage:

# Read link target
readlink symlink

# Shows target of symbolic link

Absolute Path

Full path:

# Absolute path
readlink -f symlink

# -f = canonicalize (follows all links)

---

Reading Links

Simple Link

Basic link:

# Read link
readlink /path/to/symlink

# Output: target path

Relative Link

Relative target:

# Relative link
readlink symlink

# Shows relative target path

---

Canonical Paths

Follow All Links

Canonical path:

# Follow all links
readlink -f symlink

# -f = canonicalize (resolves all links)

Real Path

Real file path:

# Get real path
readlink -f /path/to/link

# Returns absolute path to real file

---

Multiple Links

Chain Resolution

Link chains:

# Follow link chain
readlink -f link1

# Resolves: link1 -> link2 -> target

No Follow

Don't follow:

# Don't follow (default)
readlink symlink

# Shows immediate target only

---

Troubleshooting

readlink Not Found

Check installation:

# readlink is part of coreutils
# Usually pre-installed

# Check readlink
which readlink
