Quick Description

This script creates the listapps function, that can be used to list all installed programs on the computer.

Currently, it can get the list from the registry, scoop, winget, chocolatey, pip, pipx, npm, yarn and cargo.

Simple To Install

It works as a wrapper for other commands, so it is not necessary to install it.

Just copy the script file listapps.ps1 into your PowerShell profile folder ¹ and add the following line to your profile:

Invoke-Expression (Get-Content -Path .\Documents\PowerShell\listapps.ps1 -Raw)

How To Use It

To see the instructions on how to use this script, run:

listapps --help

It can be powerful when combined with tools like those on the spreadsheet.

Choice	Command	Description
⭐	fzf	Powerful Fuzzy Finder to filter the list
⭐	ripgrep	Powerful RegEx search on the list
⭐	more	Show the list in a pager
	peco	A filtering tool that is similar to fzf
	grep	grepis not available on Windows, but you can use it as an alias to ripgrepor findstr
	findstr	Similar to grep, used on Windows enviroments

And any other command that you can pipe it to!

Examples

• listapps | fzf

• listapps | rg -i "python"

• listapps --choco | fzf

Another possibility is to save the list to a file and use it with other commands:

• listapps --choco > choco_apps.txt

• listapps --yarn > yarn_packages.txt

The functions mentioned above may be implemented on this script in the future, or I may develop a whole new CLI program with a better interface and more features.

But for now, this is a simple script that works well enough for me.
