The “login shell” is a term used to define which shell (like Sh, Bash, or Zsh) will be used to load the environment variables and shell configuration files when you log into an interactive session. 💡 Once you log into your system using a pre-defined
Renaming files and directories is one of the most basic tasks that every Linux user performs regularly using the GUI or command line tools. In both of these tools, renaming a single file is pretty easy, but renaming multiple files can be trickier, especially for
When you create a directory and add files to it, any user who has access to your system and knows how to use the ls command may simply list the files in that directory and see what you have added to it. You can stop
In Linux, the rename command is an amazing utility that allows you to rename single or multiple files at once, based on a set of rules or regular expressions you specify. Most of the time, the mv command is used to rename files or folders.
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
In UNIX/Linux systems, the mv command shipped with the operating system is usually used for the following purposes: If you’re familiar with the cp command, you can use the same techniques to use the mv command. Even though you can use this article to learn
In UNIX/Linux systems, the cp command is the most commonly used command that allows you to copy files and directories from one location to another. If you don’t know how to use this command, this article will show you how to use it in a
Each command executed in your Linux terminal is being recorded by your shell (referring to Bash) in a separate file (like “~/.bash_history“) that you can view using the history command. For most Linux distributions, the number of commands that should be recorded and the number
Executing the history command without specifying any options will give you a clean record of previously executed commands with their event numbers. Output: As you can see, it does not display the date and time, so without them, you can’t even manage to filter the records. In
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
