Catenate means "to connect in a series." The cat
command displays the contents of a file. If more than
one file is placed in the command line, i.e.
cat yellow blue,
the files are displayed in succession. It is here that cat
derives its name. With the use of the redirection
operator, two files can be placed into a single
file. Typing
cat yellow blue > green
will cause green to contain the
contents of yellow followed by the
contents of blue.
