Mac に pstree が入っていなかったのでインストールしたメモ。
コマンド実行環境
$ uname -a Darwin MacBook-Pro.local 20.3.0 Darwin Kernel Version 20.3.0: Thu Jan 21 00:07:06 PST 2021; root:xnu-7195.81.3~1/RELEASE_X86_64 x86_64
Mac で pstree をインストールするには brew install pstree だけ
ps -ef でたくさんあるプロセスから特定したものの、瞬時に起動してすぐいなくなるプロセスが暴れていて
ash-3.2$ kill -9 87425 bash: kill: (87425) - No such process
としても居ないと怒られる。。
じゃあ、親プロセスを kill すればいいんじゃないかなと、おもむろに pstree
を実行するものの、
bash-3.2$ pstree bash: pstree: command not found
不在のようだ。。
brew install pstree
で入れる。
bash-3.2$ brew install pstree To `brew update`, first run: git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow This restriction has been made on GitHub's request because updating shallow clones is an extremely expensive operation due to the tree layout and traffic of Homebrew/homebrew-core and Homebrew/homebrew-cask. We don't do this for you automatically to avoid repeatedly performing an expensive unshallow operation in CI systems (which should instead be fixed to not use shallow clones).
