Question

我有一个如下所示的别名

alias testalias12569537329="echo it works"

我的问题是：如何通过连接两个字符串在shell脚本中调用testalias12569537329？

x="testalias"
x+="12569537329" #timestamp
exec $x #command not found

我知道我可以在shell脚本中直接调用testalias12569537329。但我想操纵时间戳。谢谢！

你可以这样做：

ToggleButton toggle1, toggle2;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_act);

     toggle1= (ToggleButton) findViewById(R.id.toggleButton1);
     toggle2= (ToggleButton) findViewById(R.id.toggleButton2);

       SharedPreferences spref = getSharedPreferences(null, 0);
        if(spref.getBoolean("one", false)) {
            toggle1.setChecked(true);
            toggle2.setEnabled(false);    
        } else if(spref.getBoolean("two", false)) {
            toggle2.setChecked(true);
            toggle1.setEnabled(false);    
        }

        toggle1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
            {

              toggle2.setEnabled(!isChecked);
              getSharedPreferences(null, 0).edit()
              .putBoolean("one", isChecked)
              .apply();
           startService(new           Intent(MainActActivity.this,LockScreenService.class));
            }
        });
             toggle2.setOnCheckedChangeListener(newCompoundButton.OnCheckedChangeListener() {
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
               toggle1.setEnabled(!isChecked);
               getSharedPreferences(null, 0).edit()
                   .putBoolean("two", isChecked)
                   .apply();
startService(new Intent(MainActActivity.this,PinLockService.class)); }}); }}

如何通过连接两个字符串来调用shell脚本中的别名？
