android - adb 无法在 bash 中使用变量

Question

我正在尝试从我的 android 手机(root)中导出所有 apk。

我已经使用 adb shell pm list 将所有包转储到一个文件中。

com.google.android.earscom.android.voicedialer...

Now I want to download them, but it doesn't work:

#!/bin/bash

while read line; do
        echo "Name: $line"
        # get package path
        p=$(adb shell pm path $line);
        # remove package: prefix
        p=$(echo $p | grep -Po "(?<=package:).*" | xargs)
        echo "Path: $p"
        # download it
        adb pull $p
done;

我得到这样的东西:

Name: com.google.android.earsPath: /system/app/GoogleEars.apk' does not exist/system/app/GoogleEars.apkName: com.android.voicedialerPath: /system/priv-app/VoiceDialer.apk' does not exist/system/priv-app/VoiceDialer.apkName: com.android.defcontainer^C

当我在终端中手动执行时，它工作得很好。

为什么它在这里不起作用？

正如评论中所指出的，adb 命令以 \r 结尾。你也必须从这一行中删除它

p=$(adb shell pm path $line)

用类似的东西

p=$(adb shell pm path $line | tr -d '\r')

我看到另一个问题:很多apks会被覆盖为base.apk

Name: com.google.android.youtube
Path: /data/app/com.google.android.youtube-1/base.apk
Name: net.mx17.overridedns
Path: /data/app/net.mx17.overridedns-2/base.apk
Name: com.android.email
Path: /system/app/Email/Email.apk

所以我想我会用类似的东西来做

#!/bin/bash

while read line; do
  echo "Name: $line"
  # get package path
  p=$(adb shell pm path $line | sed 's/^package://;s/\r$//')
  echo "Path: $p"
  # get package name
  name=$(echo $p | awk -F/ '{print $(NF-1)}')
  echo "Package name: $name"
  # download it
  adb pull $p ${name}.apk
done < <(adb shell pm list packages | sed 's/^package://;s/\r$//')
