Use the cp command to copy tempfile to a file called copyfile:
$ cp tempfile copyfile $ |
Now list both files. Notice that both names end with the characters “file.” You can use the wildcard character, asterisk (*), to match any character or sequence of characters. The command ls *file lists both tempfile and copyfile, and any other file in this directory with a name that ends with file.
$ ls *file copyfile tempfile |
Notice that copyfile is listed first. Files are listed in alphabetical order. Capital letters and numbers precede lowercase letters.
For detailed information on copying files, see the man page cp(1).
