pythonのsubprocess.callでchromeを終了させたい

Question

pythonのスクリプトのsubprocess.callで
現在動いているchoromeを終了させたいです．

以下のコマンドを実行しましたが，どちらも
エラー：FileNotFoundError: [Errno 2] No such file or directory:
となってしまいます．

cmd = "/usr/bin/pkill Chrome"
returncode = subprocess.call(cmd)

cmd = "/bin/ps aux | /usr/bin/awk '/Chrome/ { print $2 } ' | /usr/bin/xargs /bin/kill -9"
returncode = subprocess.call(cmd)

ご教示願います．

-追記-
Chrome実行時のps

$ ps

OSは何でしょうか?

[apeirogon0813]

Macのbig Surになります．

Answer 1

shell=True を指定しない場合、コマンドラインは以下のようにリストで指定します。

cmd = ["/usr/bin/pkill", "Chrome"]
returncode = subprocess.call(cmd)

shell=True はOSコマンドインジェクション脆弱性を混入させやすいので、上記のようにリスト指定がお勧めです。

ありがとうございます，
上記のコードで実行しても，同じエラー：FileNotFoundError: [Errno 2] No such file or directory:
がでます．おそらくChromeのパスの指定がうまくいっていないような気がします

[ockeghem]

FileNotFoundError: [Errno 2] No such file or directory は、おそらく/usr/bin/pkill の方だと思います。パス名のスペルミスと、/usr/bin/pkill が存在することのチェックをしてみたらどうですか? 私の手元の環境では動きましたよ。

[apeirogon0813]

ありがとうございます．
$ which pkill
/usr/bin/pkill
でpkillは問題ないです．
また，試しに
cmd = ["/usr/bin/pkill"]
として実行したところ
usage: pkill [-signal] [-ILfilnovx] [-F pidfile] [-G gid]
[-P ppid] [-U uid] [-g pgrp]
[-t tty] [-u euid] pattern ...
と表示されたので問題ないようです．
一方, $ which Chromeとしても
パスが表示されませんでした．
また，$ which chromeでも同様に表示されませんでした．
追記にChromeを実行中のpsを添付しておきます．

[apeirogon0813]

ちなみに，ターミナル上では
pkill Chromeで動作します．
ただ，スクリプト上で実行するとエラーになります．
