Understanding dirname

What is dirname?

dirname extracts directory from path.

Uses:

• Get directory: Extract directory path
• Remove filename: Strip filename
• Path manipulation: Process paths
• Scripts: Use in automation

Why it matters:

• Path processing: Extract directories
• Scripting: Process file paths
• Directory operations: Work with directories

dirname Basics

Extract Directory

Basic usage:

# Extract directory
dirname /path/to/file.txt

# Output: /path/to

Multiple Paths

Process several:

# Multiple paths
dirname /path/to/file1.txt /path/to/file2.txt

# Directory for each

---

Extracting Directories

From Variable

In scripts:

#!/bin/bash
FILE="/path/to/file.txt"
DIR=$(dirname "$FILE")
echo "Directory: $DIR"

From Command

With command:

# From find
find . -name "*.txt" | xargs -I {} dirname {}

# Gets directories

---

Path Manipulation

Combine with basename

Together:

#!/bin/bash
FILE="/path/to/file.txt"
DIR=$(dirname "$FILE")
NAME=$(basename "$FILE")
echo "Directory: $DIR"
echo "Filename: $NAME"

---

Troubleshooting

dirname Not Found

Check installation:

# Check dirname
which dirname

# Usually in coreutils
# Install if missing
sudo pacman -S coreutils
