  Unpacking the package...

[server]$ wp user create newusername admin@example.com --role=administrator

Changing a password

[server]$ wp user update 3 --user_pass=NEW_PASSWORD

Deleting a user

[server]$ wp user delete 13 --reassign=7

You can use the import and export commands to manage your site data with a WXR file. View the following article for details.

• Importing and exporting a WXR file

Search and replace text in your database. Make sure to use the --dry-run flag the first time to see what will change.

[server]$ wp search-replace http://example.com https://example.com/blog --dry-run

A list of fields that will be updated displays in your terminal. If you'd like to update all output displayed, run the command again without the --dry-run flag.

[server]$ wp search-replace http://example.com https://example.com/blog

1. View the current version of PHP and its location by running the following command:

   [server]$ wp cli info
   OS: Linux 4.14.117-grsec-grsec+ #1 SMP Fri May 10 17:15:47 PDT 2019 x86_64
   Shell: /bin/bash
   PHP binary: /usr/local/php74/bin/php
   PHP version: 7.4.15
   php.ini used: /etc/php74/php.ini

   WP-CLI packages dir:
   WP-CLI global config: /usr/local/wp/config.yml
   WP-CLI project config:

2. To change the version of PHP wp-cli uses, add the following line to your .bash_profile. Change the version as needed. This example uses PHP 8.0.

   export WP_CLI_PHP=/usr/local/php80/bin/php wp

3. Update the .bash_profile:

   [server]$ . ~/.bash_profile

4. Finally, check to confirm wp-cli is using this new version.
