I always have a terminal or two open in the directory of a project. The Terminal is a tool, not an application, meaning that it can be regarded as a lifestyle. The last thing you want to do is compromise your computer.

Be smart and google it, or read the manual for the command. Use Bash responsibly, and if you are unsure what something does, don't paste it into your terminal. When using Bash you are executing the power you have over the computer. If you command it to do an undesired command sequence it will proceed and execute without hesitation, which may lead to unintentional or damaging effects. Scripts are useful for automating processes or creating an easy way to perform many tasks with a single command.īash can be used to do amazing things but at the cost of responsibility. Bash is powerful because of the methods it has to link and chain commands together.īash is also a scripting language, which means you can create executable files called scripts that can run multiple commands, support control structures, variables and much more. Commands can take input in the form of arguments or interactively, and can perform operations and print output. Often executable files are called commands.
You can use Bash to run many programs and execute many many files. Bash can create directories (folders) and files with ease, and it is more straightforward than using a graphical file manager. The most convenient feature of a shell is that it operates with a working directory, which means you can navigate your file system and the shell will keep track of where you are. The interactive prompt is one of the primary methods of using a shell. (I'll be using Terminal and Bash interchangeably from now on.) On Mac and Linux this shell is Bash, but other shells can be used. When opening a terminal you are presented with a shell. The Terminal provides an efficient interface to access the true power of a computer better than any graphical interface. It is by far one of the most important applications on Mac and Linux. The Terminal, also known as the command line or a Terminal emulator, is an essential component of any useful operating system.
