How do I search for software packages to install?

Linode Staff

I'm trying to see if a specific package exists in my package manager's repositories, and am not sure where to look. How can I do this?

You can use your Linux distribution's package manager to search its repositories for a specific package. For example, to find the package for the PHP MBstring extension, you can use commands like the following:


$ apt-cache search mbstring
php-mbstring - MBSTRING module for PHP [default]
php-patchwork-utf8 - UTF-8 strings handling for PHP
php7.3-mbstring - MBSTRING module for PHP


$ yum search mbstring
