dpkg: List installed packages.

dpkg

$ dpkg -l ${pattern}

try on your machine

The command "dpkg -l ${pattern}" is used to list the installed packages that match a specific pattern.

Here is a breakdown of the command:

"dpkg" stands for "Debian Package Manager." It is a command-line tool in Debian-based Linux distributions (such as Ubuntu) for handling package management tasks.
"-l" is a flag or option for the "dpkg" command. It is short for "list" and is used to display information about installed packages.
"${pattern}" is a placeholder for the pattern that you want to match in the package names. It can be a specific package name or a regular expression pattern.

When you run the command with a specific pattern, it will display a list of installed packages that match that pattern. The output typically includes the package name, version, and a short description.

For example, if you run "dpkg -l vim", it will show information about the installed "vim" package. If you run "dpkg -l 'python'", it will display a list of installed packages containing the term "python" in their package names.
