Version 0.17 released

For the fourth WP-CLIWP-CLI WP-CLI is the Command Line Interface for WordPress, used to do administrative and development tasks in a programmatic way. The project page is release of 2014, we have a number of enhancements that will make you go “oooh” and “ahhh”.


Use wp search-replace while migrating large databases? You should submit a pull request to WP-CLI with your newly-found free time 🙂

Historically, this command performed the search and replace operation in PHPPHP PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML., as to not break arrays and objects serialized in the database.

Now, this command performs a check to see if there is any serialized data in the column it’s about to transform. If there isn’t, the command will perform a SQL search and replace. If there is serialized data, the command falls back to PHP search and replace.

One happy developer reported this new approach took 20 minutes on a large test database, compared to 8-12 hours previously — a 3,000% performance increase.

Manage languages

WordPress 4.0 lets a user pick a language on installation, or later through General Settings. WP-CLI now lets you see available languages, and install / activate one of your choosing.

$ wp core language list

Checking updates

v0.17.0 introduces two commands for checking for updates.


$ wp cli version
WP-CLI 0.16.0
$ wp cli check-update
| version | update_type | package_url                                                                   |
| 0.17.0  | minor       |        |

Or for WordPress coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress.:

$ wp core version
$ wp core check-update
| version | update_type | package_url                               |
| 4.0     | major       |   |
| 3.9.2   | minor       | |

php-cli-tools v0.10.0/1

In the recent past, we took over maintainership of php-cli-tools. WP-CLI makes use of many of its features, so we were honored to be considered when jlogsdon was looking for a new home for the project.

During the course of this release cycle, we released two new versions of php-cli-tools, v0.10.0 and v0.10.1. Together, the changeset includes:

  • cliprompt() includes an option to hide input (useful for passwords, etc.).
  • cliTable auto-wraps contents of a cell based on TTY width.
  • SHELL_PIPE environment variable can be defined for determining whether TTY is piped.
  • Fix: Add fallback for mb_strlen() when PHP mbstring extension isn’t enabled (bug introduced in v0.9.5)
  • Fix: cliColors::length() now returns correct lengths for colorized strings

Going forward, php-cli-tools’ release cycle will be tied to WP-CLI’s — and WP-CLI will run php-cli-tools dev-master to help test out new features.

Other changes


  • Full compatibility with WordPress 4.0.
  • wp core update: Caches package locally, for improved performance when updating multiple sites on the same server.
  • wp import: Import a directory of WXR files.
  • wp scaffold package-tests: Use WP-CLI’s Behat framework to add functional tests to your own command. See wiki for implementation details.
  • wp search-replace: Supports --quiet flag for verbosity.
  • wp term list: List terms for multiple taxonomies.
  • wp user import-csv: Create users from a remote CSV (e.g. stored in Dropbox or Google Drive).

  • Thanks to improvements in php-cli-tools, long strings in tables will be wrapped, instead of breaking output. See in action with wp theme get twentyfourteen.

You can browse the full list of resolved issues on GithubGitHub GitHub is a website that offers online implementation of git repositories that can easily be shared, copied and modified by other developers. Public repositories are free to host, private repositories require a paid subscription. GitHub introduced the concept of the ‘pull request’ where code changes done in branches by contributors can be reviewed and discussed before being merged be the repository owner.
