That being said, it's a three letter name. It's very unlikely NOT to run into naming conflicts here.
edge - taken by Microsoft
jpm - JPMorgan
ppm - taken by Perl package manager: https://en.wikipedia.org/wiki/Perl_package_manager
fpm - taken by Effing package management: https://github.com/jordansissel/fpm
bpm - beats per minute
ayp - terrible to type, although taken by "Adequate Yearly Progress": https://en.wikipedia.org/wiki/Adequate_Yearly_Progress
nnm - What happens when it's no longer new?
Just in Germany for example there are a ton of companies called ISIS (just google "ISIS GmbH"). Being offended by a three letter shell command seems a bit over the top to me to be honest.
Edit: I won't respond to further comments on the naming issue. It wasn't my intention to name it after a weapon. As I said earlier, I will change the name as soon as anyone proposes a better one.
