I discovered this cool command the other day: mkdir -p …
Instead of making a parent directory and subdirectories using the command line with multiple lines by doing:
mkdir parentDir then going in it with cd parentDir then making the subdirectory with mkdir subDir. You can just do mkdir -p parentDir/subDir to do everything with a single line.
You can create as many subdirectories inside as you wish: mkdir -p parentDir/subDir/subSubDir. -> This creates a parentDir with a folder inside called subDir. subDir has a folder inside called subSubDir.
The -p is what allows you to create the sub-directories inside the parent directory. It creates the parent directory if it doesn’t exist, then goes ahead and creates the subdirectories.
