The .bashrc file is a script that runs every time a new terminal session is started in Unix-like operating systems. It is used to configure the shell session, set up aliases, define functions, and more, making the terminal easier to use and more powerful. Below is a summary of the key sections and functionalities defined in the provided .bashrc file.
- Environment Checks: The script checks if it is running in an interactive mode and sets up the environment accordingly.
- System Utilities: It checks for the presence of utilities like
fastfetch,bash-completion, and system-specific configurations (/etc/bashrc).
- Aliases: Shortcuts for common commands are set up to enhance productivity. For example,
alias cp='cp -i'makes thecpcommand interactive, asking for confirmation before overwriting files. - Functions: Custom functions for complex operations like
extract()for extracting various archive types, andcpp()for copying files with a progress bar.
