[英]Running shell script in Android adb shell
I'm trying to create a script to find and remove my app from the Android emulator through the adb shell. 我正在尝试创建一个脚本,以通过adb shell从Android模拟器中查找和删除我的应用。
This is what I've got: 这就是我得到的:
adb shell "
cd data/app
for app in com.mycompany.*.apk;
do
echo $app
bundle=$(echo $app | sed 's/-[0-9]//g')
echo 'bundle name is $bundle'
if [ '$bundle' != '' ];then
adb uninstall $bundle
else
echo 'No apps found'
fi
done
exit
"
But it doesn't seem to work as expected. 但是它似乎没有按预期工作。
for
loop doesn't iterate through anything. 我的for
循环不会遍历任何东西。 If I manually run the commands exactly as above in the shell, it works, but when I run it from a shellscript then the for
loop doesn't see the files or anything. 如果我在外壳中完全按照上面的命令手动运行命令,则它可以工作,但是当我从shellscript运行命令时, for
循环将看不到文件或任何内容。 Although if I add an "ls", it prints the contents of the folder correctly... So; 尽管如果添加“ ls”,它会正确打印文件夹的内容。 echo $app
prints nothing (an empty string) and; echo $app
输出任何内容(空字符串),并且; echo 'bundle name is $bundle'
prints bundle name is
. echo 'bundle name is $bundle'
打印bundle name is
。 Therefore, it obviously never goes inside my if block, falling in to my else clause and that's it. 因此,它显然永远不会进入我的if块,而落入我的else子句中。
What am I doing wrong? 我究竟做错了什么? I'm not very experienced in shell script, I'd appreciate any ideas. 我对shell脚本不是很有经验,我会很感激任何想法。
My goal with this is to have a shell function that I can call to automate the process of removing my app from the emulator without having to drag it and uninstall it manually. 我的目标是拥有一个shell函数,可以调用它来自动执行从模拟器中删除应用程序的过程,而无需手动拖动和卸载它。 Other ideas are also very much welcome. 其他想法也非常受欢迎。
Thanks! 谢谢!
You should not really go through the /data/app
folder. 您不应该真正浏览/data/app
文件夹。 If you want to uninstall multiple packages with names matching the com.mycompany
pattern with a single adb command use: 如果要使用单个adb命令卸载名称与com.mycompany
模式匹配的多个软件包,请使用:
adb shell "pm list packages com.mycompany | cut -c9- | xargs -n 1 sh /system/bin/pm uninstall"
I'm still curious to know why my approach was "suboptimal" and what could I have done better? 我仍然想知道为什么我的方法“次优”,我能做得更好吗?
Wild guess since I'm not familiar with adb shell but bash: Quotation. 大胆猜测,因为我对adb shell不熟悉,但对bash却很:报价。 Variables can not be inside ticks '...$VAR' but "...$VAR". 变量不能在刻度“ ... $ VAR”内,而应在“ ... $ VAR”内。 Anything inside ticks is taken "as is", ie literally: 滴答中的所有内容均按“原样”进行,即从字面上看:
echo 'bundle name is $bundle'
vs. 与
echo "bundle name is $bundle"
