I just installed mtr
via Homebrew, and it completed seemingly successfully (i.e., nothing unusual).
MBA% mtr
zsh: command not found: mtr
That's odd. I figured I'd try again:
MBA% brew install mtr
Warning: mtr-0.86 already installed
Okay, maybe it's symlinked as mtr-0.86
:
MBA% mtr-0.86
zsh: command not found: mtr-0.86
Nope, okay, maybe it just failed to link:
MBA% brew link mtr
Warning: Already linked: /usr/local/Cellar/mtr/0.86
To relink: brew unlink mtr && brew link mtr
MBA% brew unlink mtr && brew link mtr
Unlinking /usr/local/Cellar/mtr/0.86... 3 symlinks removed
Linking /usr/local/Cellar/mtr/0.86... 2 symlinks created
MBA% mtr zsh: command not found: mtr
However:
MBA% /usr/local/Cellar/mtr/0.86/sbin/mtr
[Success]
What's going on? Why is Homebrew failing to link (and creating fewer symlinks on relinking for that matter..)?
mtr
needs root. Yes. By [Success] I mean it complained about just that, rather than failing to even run.)
