Apart from using exec.Command, is there a better way to check version of any external system app in /usr/local/bin like fzf or nodejs using go?

• go-mtree

  7 73 5.5 Go

  File systems verification utility and library, in likeness of mtree(8)

SHA1 is dead, and there is a better dedicated tool mtree(8) for such tasks (which by the way exists as implementation in Go as go-mtree ) but I believe OP wants to check versions (like fzf --version) not an integrity of files

• sha1collisiondetection

  7 1,288 0.0 C

  Library and command line tool to detect SHA-1 collision in a file

I'm saying that Git is on my side of opinion, that's why Git added collision detection (hardened SHA1) and added support for more stronger hashes and Git's goal is transition out of SHA1. The same is with fossil, that added hardened SHA1 since 2017 and by default uses SHA3 for new repositories.
