cp * satire/
In addition to using filenames as arguments, we can use special characters like
* to select groups of files. These special characters are called wildcards. The
* selects all files in the working directory, so here we use
cp to copy all files into the satire/ directory.
cp m*.txt scifi/
m*.txt selects all files in the working directory starting with "m" and ending with ".txt", and copies them to scifi/.
