The command "gem list" is used in the Ruby programming language to list all the gems (software packages or libraries) that are installed on your system.
When you run "gem list" in the terminal or command prompt, it will display a list of all the gems installed on your system along with their versions. This command is helpful when you want to check which gems are currently installed and their respective versions, especially if you are working on a Ruby project and want to ensure all necessary dependencies are met.
The output of the command typically includes information such as the gem name, version, and a brief description of each gem.
