📦 How to Extract wp-content.tar.gz on Linux

If you’re restoring a WordPress backup or moving files between servers, you may come across archive files like wp-content.tar.gz or wp-content.zip. Here’s how to safely extract them using the command line.

1. For .tar.gz Files

Run the following command to extract a .tar.gz archive in the current directory:
```
tar -xzvf wp-content.tar.gz
```
Explanation of flags:
- x — extract
- z — uncompress gzip
- v — verbose (show progress)
- f — specify filename
To extract into a specific directory:
```
tar -xzvf wp-content.tar.gz -C /home/naomiso/naomisophyblog.com.ng/wp-content/
```
2. For .zip Files

If your archive is a .zip file, use the unzip command:
```
unzip wp-content.zip
```
To extract to a specific folder:
```
unzip wp-content.zip -d /home/naomiso/naomisophyblog.com.ng/wp-content/
```
🔧 Need to Install tar or unzip?

If these commands are missing on your server, install them with:

For Ubuntu
```
sudo apt install tar
sudo apt install unzip

For AlmaLinux
sudo yum install tar
sudo yum install unzip
```
✅ Conclusion

Now you know how to handle both .tar.gz and .zip files when working with WordPress backups on a Linux server. Always make sure you’re extracting into the correct directory and have the right permissions set for www-data or your web user.

Terminal: How to Change a WordPress User Password via MySQL (User: coic)
🔐 How to Change WordPress Admin Password via MySQL (User: coip)
Last updated: July 3, 2025
🧰 Requirements

Access to your Linux server (SSH or terminal)

MySQL root access or database credentials

WordPress database name: zzle_wu
🛠 Resetting the Password Using MySQL

Run the following command to reset the password for the user coic:

mysql -u root -p -e "UPDATE zzle_wu.wp_users SET user_pass = MD5('favour2025') WHERE user_login = 'coip';"

This command uses the MD5 hashing algorithm, which is required by older WordPress versions to store passwords in the database.
⚠️ Security Warning

MD5 is outdated and no longer considered secure. Although WordPress still supports it, newer versions use stronger hashing algorithms like bcrypt.

After logging in with the new password, it’s recommended to immediately update the password again through the WordPress dashboard or WP-CLI to ensure it’s rehashed securely.
✅ More Secure Alternative Using WP-CLI

If WP-CLI is available on your server, use this command instead for modern hashing:

wp user update coip --user_pass=favour2025

This is the preferred and more secure method to reset a WordPress password.
📌 Tip: Always backup your database before performing manual operations.
