The  “[ -f ~/.bashrc]” is known as a test command in bash. This command, which includes the “-f” expression,  will check if the ~/.bashrc file exists  (i.e. the file .bashrc is in your home directory) and is a regular file (i.e. is not a directory).

If the expression [ -f ~/.bashrc] is true, then the program will run the  “source ~/.bashrc” command.
