In Linux, you use the useradd, passwd, usermod, and gpasswd commands to modify users or group-related information, like creating them, deleting them, assigning passwords, etc. Note that these commands only provide you an interface to modify the “/etc/passwd“, “/etc/shadow“, “/etc/group“, and “/etc/gshadow” files with safety
The Linux shell (specifically, “Bash“) records all the commands you run in your terminal and stores them in the “.bash_history” file in your home directory. You can use tools like the history command, which provides you many features and functionality to work with this file,
The Linux shell (specifically, “Bash“) takes each executed command as an event and saves the command in the “.bash_history” file located in the user’s home directory. Now, there are two ways to view the history record of a user’s executed command: one using the history

Each command executed in your Linux terminal is taken as an event and associated with an event number (or index number) later found in the “~/.bash_history” file. Now, you can use a program like a “cat” to read the record of this file, but Linux
