  • What are the differences between su, sudo -s, sudo -i, sudo su?
    sudo su Asks your password, becomes root momentarily to run su as root sudo su - Asks your password, becomes root momentarily to run su - as root So in this case you are running su using sudo and you don't have to know root's actual password The results are same as su and su -
  • su - user Vs sudo su - user - Unix Linux Stack Exchange
    8 sudo su - will elevate any user (sudoer) with root privilege su - anotheruser will switch to user environment of the target user, with target user privileges What does sudo su - username mean?
  • What is the difference between su - and su root? [duplicate]
    8 su - switches to the superuser and sets up the environment so that it looks like they logged in directly su root switches to the user named root and doesn't simulate directly logging in If the superuser is named root, then su and su root are equivalent (and don't simulate directly logging in), as are su - and su - root (which do)
  • su vs sudo -s vs sudo -i vs sudo bash - Unix Linux Stack Exchange
    su is equivalent to sudo -i and simulates a login into the root account Your working directory will be root, and it will read root's profile etc The prompt will change from $ to #, indicating you have root access sudo -s launches a shell as root, but doesn't change your working directory sudo bash where bash is command to run with sudo
  • Whats the difference between `su -` and `su --login`? - linux
    From su 's man page: For backward compatibility, su defaults to not change the current directory and to only set the environment variables HOME and SHELL (plus USER and LOGNAME if the target user is not root) It is recommended to always use the --login option (instead of its shortcut -) to avoid side effects caused by mixing environments -, -l, --login Start the shell as a login shell
  • 急！！！有没有人知道，su添加贴图但是文件夹中找不到？ - 知乎
    我的 SketchUp2023 也是出现这个问题，后来发现只是添加贴图的时候JPG文件不能显示，而如果把路径选好，文件名复制后粘贴到文件名框里，点打开就行了。前提是路径和文件名正确。
  • Why do we use su - and not just su? - Unix Linux Stack Exchange
    su - logs you in completely as root, whereas su makes it so you are pretending to be root The most obvious example of this is that ~ is root's home directory if you use su -, but your own home directory if you use su
  • su: Permission denied despite correct password
    In my new Gentoo installation, su doesn't work as my non-root user: After entering the correct password I get the message "su: Permission denied" What could be causing this? I have already tried
  • Why am I getting Authentication failure when running the su command . . .
    I am having problems with the su command I know my password and I am typing it correctly, but su indicates Authentication failure So I checked on the internet and then went into recovery mode and
  • Is there a single line command to do `su`? - Ask Ubuntu
    Here's why: If you write a password in a command like su <username> -p <password>, it would be stored in plain text in your bash history This is certainly a huge security issue If you need to run commands with su (or sudo) in an automated way, write a shellscript containig the commands without su or sudo and run su <username> script sh
