Very nice bash shell prompt
This is a very useful Linux shell prompt with color.
export PS1="\[\033[38;5;165m\]\d\[$(tput sgr0)\] \[$(tput sgr0)\]\[\033[38;5;51m\]\W\[$(tput sgr0)\] \[$(tput sgr0)\]\[\033[38;5;84m\]\H\[$(tput sgr0)\]@\[$(tput sgr0)\]\[\033[38;5;229m\]\u\[$(tput sgr0)\]:\l>\[$(tput sgr0)\]\[\033[38;5;231m\]\\$\[$(tput sgr0)\] " |
This prompt will look like this.

Create a new user on Linux with the command line
Creating a new user with the Linux command-line is very easy. The adduser command automates a lot of steps and is very easy to use. This will create a user`s home directory and put in all of the needed dotfiles to set up their new user account.
Mon Mar 30 ~ Yog-Sothoth@jason:0>$ sudo adduser mint Adding user `mint' ... Adding new group `mint' (1002) ... Adding new user `mint' (1002) with group `mint' ... Creating home directory `/home/mint' ... Copying files from `/etc/skel' ... Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully Changing the user information for mint Enter the new value, or press ENTER for the default Full Name []: John Smith Room Number []: 13 Work Phone []: 789945678 Home Phone []: Other []: Is the information correct? [Y/n] y |
The userdel command is used to remove a user from the system. This procedure is shown below.
Mon Mar 30 ~ Yog-Sothoth@jason:0>$ sudo userdel -r mint |
The -r parameter will recursively erase the home folder of the user and their files. Similar to using rm -rf /home/mint and erasing their folder. But the userdel -r mint command is safer than typing rm -rf --no-preserve-root willy nilly as the root user. That is dangerous. Sure, rm -rf /files would work, but better to use something like this instead.
Mon Mar 30 ~ Yog-Sothoth@jason:0>$ rm -rvf stuff/ removed directory 'stuff/stuff2' removed directory 'stuff/stuff' removed directory 'stuff/stuff3' removed directory 'stuff/' |
That will delete the directory and all subdirectories in a safer way. The rmdir --ignore-fail-on-non-empty stuff/ command did not work for me.
