        "content": "Here are commands and explanations for creating a user `brh` on Debian 13, with a group of the same name (if needed), and creating a home directory.\n\n---\n\n## \u2705 Recommended Method: `useradd`\n\nThis is a lower-level tool, but gives you more control with flags.\n\n```\nsudo useradd -m -U -s /bin/bash brh\n```\n\nWhat each option does:\n\n- `-m` or `--create-home`: create the home directory (`/home/brh`) and copy default files from `/etc/skel`. ([linuxize.com](https://linuxize.com/post/how-to-create-users-in-linux-using-the-useradd-command/?utm_source=openai))  \n- `-U` or `--user-group`: create a group with the same name as the user `brh` and make that the user\u2019s primary group. ([manpages.debian.org](https://manpages.debian.org/man/useradd?utm_source=openai))  \n- `-s /bin/bash`: set the user\u2019s login shell to `/bin/bash` (you can change this to whatever shell you prefer).  \n\nAfter running this, you\u2019ll want to set the password:\n\n```\nsudo passwd brh\n```\n\n---\n\n## \ud83d\udd04 Alternative: `adduser`\n\nDebian has a higher-level utility `adduser` which automates many steps like creating the home directory and also handles creating a group with the same name. If all you need is a standard user, this is simpler:\n\n```\nsudo adduser brh\n```\n\nYou will be prompted interactively for a password, full name, etc. It creates the home directory, assigns a user group, etc. ([debian.club](https://www.debian.club/en/administration/users?utm_source=openai))\n\nYou can also use some options with `adduser` to control certain behavior, but often it\u2019s used straight as above.\n\n---\n\n## \ud83d\udccb Summary\n\n| Goal | Command |\n|------|---------|\n| Create user `brh`, group `brh`, home directory `/home/brh`, using Bash shell | `sudo useradd -m -U -s /bin/bash brh` + `sudo passwd brh` |\n| Same using interactive tool | `sudo adduser brh` |\n\n---\n\nIf you want the group to already exist (and then assign `brh` to it), you can do:\n\n```\nsudo groupadd brh    # only if group doesn\u2019t already exist\nsudo useradd -m -g brh -s /bin/bash brh\nsudo passwd brh\n```\n\nHere:\n\n- `-g brh` sets the primary group to an existing group named `brh`.  \n- Note: without `-U`, `useradd` will **not** automatically create a group unless the `USERGROUPS_ENAB` setting in `/etc/login.defs` is enabled or you use `-U`. ([manpages.debian.org](https://manpages.debian.org/man/useradd?utm_source=openai))\n\n---\n\nIf you want, I can also give you a full step-by-step script or explain how to check afterward that everything (home directory, group, permissions) is set up correctly."
