UNIX provides several ways to select groups of files based
on name patterns (Table 1.1):
Table 1.1:UNIX wildcards
Code
Meaning
*

?
Matches any single character
[list]
Matches characters in the list
[range]
Matches characters in the given range
You can save much time by getting into the habit of selecting
``good'' filenames that make it easy to select subsets of all
files using the UNIX wild card notation.
