Linux ->> Sudo命令

Linux下切换用户的命令。比较常用的用法：

1）不切换当前用户，只用指定用户的权限去执行一条命令

jerry@ubuntu:/tmp$ su -c "ls /tmp" root
Password: 
?           ThisDIr         vmware-file-mod0
config-err-6ha607  unity_support_test.0  vmware-guest-oPvIa8
config-err-NDGsUe  vgauthsvclog.txt.0     vmware-guest-QC4Egw
config-err-yvEI5R  VMTools         vmware-jerry
dir2           vmware-config0     vmware-root

2)切换用户并指定bash
