If you're just starting out with Bash, it's important to learn the basic commands that you'll be using over and over again. One of the most useful commands is ls, which is used to display the contents of a directory. To list all of the files in the current directory, simply type ls into your terminal. If you want to see more information, such as file permissions and ownership, use the -l flag: ls -l.
Another useful command is cd, which is used to change directories. To move into a different directory, simply type cd followed by the name of the directory. For example, if you want to move into a directory called projects, you would type cd projects. You can also use cd with relative or absolute paths, such as cd /usr/bin or cd ../parent_directory.
The mkdir command is used to create new directories. To make a new directory called test, simply type mkdir test. This will create a new directory called test in the current directory. You can also create multiple directories at once by separating the names with spaces: mkdir test1 test2 test3.
Finally, the rm command is used to remove files and directories. To remove a file called example.txt, simply type rm example.txt. If you want to remove a directory and all of its contents, use the -r flag: rm -r directory_name.
These are just a few of the that you'll need to know as you start working with Python. By mastering these commands and practicing basic Bash techniques, you'll be well on your way to mastering Python and unleashing the power of Bash scripts in your code!
Running Bash Scripts in Python
