如何在 Chrome 关闭时执行脚本

Question

我想在每次Chrome退出时都使用rsync对书签进行时间戳备份。如何在 Chrome 关闭后立即触发脚本执行？

编辑：

这是使用我尝试实现的解决方案在Linux Mint上启动Chrome的默认执行脚本：

#!/bin/bash

# Let the wrapped binary know that it has been run through the wrapper.
export CHROME_WRAPPER="`readlink -f "$0"`"
HERE="`dirname "$CHROME_WRAPPER"`"

"/opt/google/chrome/chrome" & pid=$!
wait $pid
if ! pgrep chrome > /dev/null; then
  echo "It exited successfully"
fi

# Check if the CPU supports SSE2. If not, try to pop up a dialog to explain the
# problem and exit. Otherwise the browser will just crash with a SIGILL.
# http://crbug.com/348761
grep ^flags /proc/cpuinfo|grep -qs sse2
if [ $? != 0 ]; then
  SSE2_DEPRECATION_MSG="This computer can no longer run Google Chrome because 
its hardware is no longer supported."
  if which zenity &> /dev/null; then
    zenity --warning --text="$SSE2_DEPRECATION_MSG"
  elif which gmessage &> /dev/null; then
    gmessage "$SSE2_DEPRECATION_MSG"
  elif which xmessage &> /dev/null; then
    xmessage "$SSE2_DEPRECATION_MSG"
  else
    echo "$SSE2_DEPRECATION_MSG" 1>&2
  fi
  exit 1
fi
# We include some xdg utilities next to the binary, and we want to prefer them
# over the system versions when we know the system versions are very old. We
# detect whether the system xdg utilities are sufficiently new to be likely to
# work for us by looking for xdg-settings. If we find it, we leave $PATH alone,
# so that the system xdg utilities (including any distro patches) will be used.
if ! which xdg-settings &> /dev/null; then
  # Old xdg utilities. Prepend $HERE to $PATH to use ours instead.
  export PATH="$HERE:$PATH"
else
  # Use system xdg utilities. But first create mimeapps.list if it doesn't
  # exist; some systems have bugs in xdg-mime that make it fail without it.
  xdg_app_dir="${XDG_DATA_HOME:-$HOME/.local/share/applications}"
  mkdir -p "$xdg_app_dir"
  [ -f "$xdg_app_dir/mimeapps.list" ] || touch "$xdg_app_dir/mimeapps.list"
fi

else

您使用的是什么操作系统？在OS X中，这个shell脚本将启动Chrome，然后在Chrome退出时do stuff - 在任何类Unix操作系统中适应您的需求应该很容易。

#! /usr/bin/env sh
"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" & pid=$!
wait $pid
if ! pgrep Chrome > /dev/null; then     # no instances of Chrome are running
  # do stuff
fi

（基于这个答案）

编辑：这在 Ubuntu 中对我有用：

#! /usr/bin/env sh
/opt/google/chrome/chrome & pid=$!
wait $pid
if ! pgrep chrome > /dev/null; then
  # do stuff
fi

由于谷歌浏览器使用进程的方式，监控（PID）特定谷歌浏览器窗口（或实例）的进程通常是一个令人头疼或（几乎）不可能。

但是，有一种解决方法可以使这成为可能。只需使用指向/tmp文件夹 （ --user-data-dir=/tmp ） 的 --user-data-dir 参数

。

下面，为了说明，我创建了一个bash脚本，用于启动http Web服务Gitea，在Google Chrome中打开它，然后在Google Chrome窗口关闭时终止它。

#!/bin/bash
gitea & GITEA_PID=$!
sleep 3
google-chrome-stable --user-data-dir=/tmp --app=http://0.0.0.0:3000/ & CHROME_PID=$!
wait $CHROME_PID
kill -9 $GITEA_PID

基本上我正在使用你同样的想法。只是适应。🥰
