macos - 尝试在脚本中使用“rm”

问题描述

我编写了这个 bash 脚本来删除旧版本的 Mac 应用程序并安装新版本。一切正常，除了在安装新应用程序之前似乎没有删除应用程序 - 相反，它似乎覆盖了它的顶部，这在您尝试启动应用程序时会导致一些问题。想知道我的脚本哪里出错了 - 任何帮助都将不胜感激。

#!/bin/sh

#Script to remove the old version of 8x8 Virtual Office and the install the latest version.


APP=/Applications/8x8\ -\ Virtual\ Office.app
VERSION=$(defaults read /Applications/8x8\ -\ Virtual\ Office.app/Contents/Info | grep CFBundleShortVersionString | cut -c35-39)
#See Script options in JSS for $4 value
LATEST="$4"
pid=$(ps -fe | grep '8x8 - Virtual Office' | grep -v grep | awk '{print $2}')

if test -e "$APP" ; then

  if [ "$VERSION" \< "$LATEST" ] ; then
    echo "8x8 Virtual Office $VERSION found"
    echo "Application needs updating..."

    if [[ -n $pid ]]; then
      echo "Quitting application first..."
      kill $pid
      sleep 5s
      echo "Removing old version..."
      rm -f $APP
      sleep 5s 
      echo "Installing new version..."
      jamf policy -event install88
    else
      echo "Application not running, removing old version..."
      rm -f $APP
      sleep 5s 
      echo "Installing new version..."
      jamf policy -event install88
      exit 0
    fi

  else
    echo "No update required"
    exit 0
  fi

else
  echo "8x8 Virtual Office not found, installing..."
  jamf policy -event install88
    exit 0
fi

解决方案

APP=/Applications/8x8\ -\ Virtual\ Office.app

您的路径包含空格。所以删除命令应该是rm -f "$APP"

演示：

:=>APP=/Applications/8x8\ -\ Virtual\ Office.app
:=>echo $APP
/Applications/8x8 - Virtual Office.app
:=>rm $APP
rm: cannot remove '/Applications/8x8': No such file or directory
rm: cannot remove '-': No such file or directory
rm: cannot remove 'Virtual': No such file or directory
rm: cannot remove 'Office.app': No such file or directory
:=>rm "$APP" 
rm: cannot remove '/Applications/8x8 - Virtual Office.app': No such file or directory
:=>

在上面的演示中，当我们执行rm 命令时， 由于路径中有空格，rm $APP 所以需要 4 个参数Applications/8x8, -, Virtual , 。Office.app`
