本文转自: 个人建议 Ubuntu下修改目录权限命令如下:chmod 600 name (只有所有者有读和写的权限)chmod 644 name (所有者有读和写的权限,组用户只有读的权限)chmod 700 name (只有所有者有读和写以及执行的权限)chmod 666 name (每个人都有读和写的权限)chmod 777 name (每个人都有读和写以及执行的权限) 其中 name 指文件名,也可以是目录名. 整个命令的形式是chmod ×××(所有者)×××(组用户)×××(其他用户)
Cannot find ./catalina.sh The file is absent or does not have execute permission This file is needed to run this program 没有给bin目录下的文件授权可执行权限: chmod +x bin/*.sh
打开777权限 public class SystemManager extends Activity { public static boolean RootCommand(String command){ Process process = null; DataOutputStream os = null; try{ process = Runtime.getRuntime().exec("su"); os = new DataOutputStream(process.getOut
1.工具栏放下面或者左边的命令 gsettings set com.canonical.Unity.Launcher launcher-position Left gsettings set com.canonical.Unity.Launcher launcher-position Bottom 2.查看Ubuntu版本 cat /etc/issue
