How can I modify the default home directory for a specific user in a Linux system?

I’ve been diving into Linux lately, and I’ve hit a bit of a wall. So, I have this situation where I need to change the default home directory for a specific user in my Linux setup, but I’m not exactly sure how to go about it. I’ve read a few tutorials online, and they all seem to assume a level of expertise that I definitely don’t have yet.

Here’s the thing: I created a user named “john” for some testing purposes, and I want his home directory to be located in a different place than the typical `/home/john`. I was thinking maybe `/data/users/john`, but I’m worried that if I just manually move things around, I might mess stuff up or leave some configurations pointing to the old home directory. I want to do this the right way, and ideally, without having to recreate the user.

I’ve seen commands like `usermod` floating around, and that seems like it might be what I need, but I don’t fully understand how to use it properly. Do I just provide the new directory as an argument, or is there a specific format I need to follow? Plus, once I change the home directory, are there any permissions I need to be aware of? I don’t want John to end up with read/write issues or anything like that.

On a related note, if I change the home directory, would this affect any of the files or settings he currently has? I assume the contents would need to be copied over to the new location, right? If that’s the case, what’s the best way to do that without losing any data?

I could really use some guidance on this. If anyone has done something similar, I’d appreciate any tips or steps to follow. It’s a bit daunting, and I really want to learn the right approach to handle user management in Linux. Thanks in advance for any help you can provide!

    1. Changing the default home directory for a user in Linux can seem tricky at first, but it’s pretty manageable if you follow the right steps. Since you’ve already got a user named “john” and want to move his home directory from the usual /home/john to /data/users/john, you’re on the right track!

      First, you’re correct that the usermod command is what you need. Here’s a simple way to do it:

      sudo usermod -d /data/users/john john

      In this command:

      • sudo runs the command with superuser privileges because changing user information usually requires it.
      • usermod is the command used to modify user accounts.
      • -d specifies the new home directory.
      • john is the username you’re modifying.

      Now, after you run that, that changes John’s home directory, but you’ll also want to make sure you move all his existing files to the new location. You can do that using the mv command:

      sudo mv /home/john/* /data/users/john/

      This command moves all the files from /home/john to /data/users/john. Note that you might want to create the new directory first if it doesn’t exist:

      sudo mkdir -p /data/users/john

      As for permissions, you’ll want to set the right permissions for the new directory so John can access it properly:

      sudo chown john:john /data/users/john

      This command changes the ownership of the new home directory to John, ensuring he has the right access. After all this, check that everything’s there by switching to John’s user:

      su - john

      Now, regarding your question about losing files or settings: as long as you follow these steps correctly and move his files over, he shouldn’t lose anything. Just be careful during the mv process. If you want to double-check before you do anything, you could always back up the original /home/john just in case.

      In summary:

      1. Use usermod to change the home directory.
      2. Move files to the new location.
      3. Set the proper permissions so John can access it.

      That should set you on the right path! Good luck!

    2. To change the default home directory for the user “john,” you can indeed use the `usermod` command, which is designed for modifying user accounts in Linux. The command you’d want to use is: sudo usermod -d /data/users/john john. This will set the new home directory to your desired path. Remember to include the -d option to indicate that you’re changing the home directory. Additionally, to avoid any permission issues, you should also copy the existing contents from the old home directory to the new location. You can do this using the cp -a command: sudo cp -a /home/john/. /data/users/john/. The -a option preserves the file attributes, ensuring that files maintain their ownership and permissions.

      After you’ve moved the files, make sure to verify the ownership of the new home directory by running sudo chown -R john:john /data/users/john. This will ensure that “john” has the correct permissions to read and write to his new home directory. Changing the home directory shouldn’t affect any existing user settings or files, as long as you’ve moved the data over to the new location correctly. Once you’ve done this, you should be good to go, and “john” will have all his files and configurations in the new home directory. It’s always a good practice to double-check everything—especially permissions—after such changes.
