Description of issue

What happen when the command is same for different formulas?

Brew documentation mention this but it seem about name conflict rather the command conflict

When Homebrew already has a formula called foo we typically do not accept requests to replace that formula with something else also named foo. This is to avoid both confusing and surprising users’ expectations.

For example if there is two formulae named, foo and better-foo but use the same command foo how does brew handle it?

When I say 'command' I am referring to [1] part

┌1┐
git checkout master

As a general rule of thumb, we may try to install a binary/command by a different name for one of the formulae. One example of this is in the fcrackzip formula, where zipinfo is renamed to fcrackzipinfo to avoid conflicts with zipinfo provided from unzip.

In cases where it is not sensible to rename the binary/command in either of the formulae, the conflicts_with stanza can be used to indicate that the two formulae can't be installed simultaneously (brew install would otherwise fail on the link step, refusing to overwrite the symlink to binary of the other formula). One example of this is the conflict marked between yq and python-yq. Note that the conflict must be denoted on both sides (or, in the case of a three-way conflict, all three formulae must declare a conflict with the other two).
