Unix安装程序找不到文件的路径，即使我输入了确切的路径

Question

我正在尝试修改更新Flash的现有脚本，但安装程序不起作用。

我不断收到以下错误。

安装程序：错误的指定包路径无效："/卷/Flash Player/安装 Adobe Flash Player.app/Contents/MacOS/Adobe Flash Player 安装管理器"。

如果我将其修改为在文件路径的末尾说包含.pkg，它也不起作用。

以下是脚本的其余部分：

#!/bin/sh
# Script to download and install Flash Player.
# Only works on Intel systems.
#
dmgfile="flash.dmg"
volname="Flash"
logfile="FlashUpdateScript.log"
echo "Updating Flash player…"
# Are we running on Intel?
if [ '`/usr/bin/uname -p`'="i386" -o '`/usr/bin/uname -p`'="x86_64" ]; then
    # Get the latest version of Flash Player available from Adobe's About Flash page.
    latestver=`/usr/bin/curl -s http://www.adobe.com/software/flash/about/ | sed -n '/Safari/,/</tr/s/[^>]*>([0-9].*)<.*/1/p'`
    # Get the version number of the currently-installed Flash Player, if any.
    if [ -e "/Library/Internet Plug-Ins/Flash Player.plugin" ]; then
    currentinstalledver=`/usr/bin/defaults read /Library/Internet Plug-Ins/Flash Player.plugin/Contents/version CFBundleShortVersionString`
    else
    currentinstalledver="none"
    fi
    echo "Installed version:                 $currentinstalledver"
    echo "Currently last version to install: $latestver"
# Compare the two versions, if they are different of Flash is not present then download and install the new version.
if [ "${currentinstalledver}" != "${latestver}" ]; then
    echo "UPDATING…"
    /bin/echo "`date`: Current Flash version: ${currentinstalledver}" >> ${logfile}
    /bin/echo "`date`: Available Flash version: ${latestver}" >> ${logfile}

    newlyinstalledver=`/usr/bin/defaults read /Library/Internet Plug-Ins/Flash Player.plugin/Contents/version CFBundleShortVersionString`
        if [ "${latestver}" = "${newlyinstalledver}" ]; then
            /bin/echo "`date`: SUCCESS: Flash has been updated to version ${newlyinstalledver}" >> ${logfile}
            echo "SUCCESS: Flash has been updated to version ${newlyinstalledver}"
        else
            /bin/echo "`date`: ERROR: Flash update unsuccessful, version remains at ${currentinstalledver}." >> ${logfile}
            /bin/echo "--" >> ${logfile}
            echo "ERROR: Flash update unsuccessful, version remains at ${currentinstalledver}."
        fi
    # If Flash is up to date already, just log it and exit.       
    else
        /bin/echo "`date`: Flash is already up to date, running ${currentinstalledver}." >> ${logfile}

echo "ERROR: This script is for Intel Macs only."
fi

您需要确认路径的每个段都具有允许您写入该目录及其下的任何目录的权限。将以下脚本保存到 PATH 中的目录中（/usr/local/bin合适），或将其保存到 /tmp 目录中并将其与完整路径一起使用。

cat pathChecker.sh    
#!/bin/bash
path2chk="${@?usage:${0##*/} /path/to/check}"
if ! [[ -d "${path2chk}" ]] ; then
   echo "no directory access to ${path2chk}"
   echo "checking all elements anyway"
fi
echo "${path2chk}"
| sed 's///n/g' 
| while read pathElem ; do
    testPath="${testPath+${testPath}/}${pathElem}"
    #dbg echo "ls -ld "$testPath""
    ls -ld "$testPath"
done

chmod +x pathChecker.sh
pathChecker.sh '/Volumes/Flash Player/Install Adobe Flash Player.app/Contents/MacOS/Adobe Flash Player Install Manager'

应该显示这样的列表

drwxr-x-r-x ..... /Volumes
drwxr------ ..... /Volumes/Flash Player   # bzt!
. . . .
