Uninstall all programs installed by Homebrew

I am wondering if there is a way to uninstall all "programs" installed by Homebrew? I was using it and installed programs that corresponded to programming or using C/C++ and used the terminal to compile it but will not be using it in a few months.

According to the homebrew FAQ, to uninstall homebrew you use:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

If you don’t want to completely uninstall home-brew but just want to remove all packages installed by homebrew, I think this will do what you need (I’m not currently in a position to remove all of my packages to check):

while [[ `brew list | wc -l` -ne 0 ]]; do
    for EACH in `brew list`; do
        brew uninstall --force --ignore-dependencies $EACH
    done
done

This will get a list of all the installed packages and loop over them removing one at a time, ignoring any dependencies.

I’ve enclosed the whole thing in a loop double check that after the first run all of the packages have been uninstalled — I’m pretty sure they will be due to the --force and --ignore-dependencies options, but belt and braces...

I usually just do

brew remove --force $(brew list --formula)

and

brew remove --cask --force $(brew list)

The answers didn't work for me, but the following did (Homebrew 2.4.9, Feb 17 2021):

brew list | xargs brew uninstall --force

I also had a few casks installed, this removed them as well:

brew list --cask | xargs brew uninstall --force

Here is what I used:

for f in `brew list`; do 
    brew uninstall --ignore-dependencies --force $f
done

for f in `brew list --formula`; do 
    brew uninstall --ignore-dependencies --force $f
done

Because nowadays it requires brew list --formula or else you will get an error

Error: Invalid usage: this command requires a formula or cask argument
