ls into your terminal. If you want to see more information, such as file permissions and ownership, use the
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
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.
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
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!
