# RM-RF! (File1|file2)

First Shopt-s Extglob under the popular science

The Bash Shell has a extglob option that allows the shell to identify 5 additional pattern matching operators, which makes it easier to match files.

The Open method is simple, using the shopt command: Shopt-s extglob
Close, use the shopt command: Shopt-u extglob

After opening, the following 5 pattern matching operators will be identified:

? (pattern-list)-the given pattern matches 0 or 1 times, * (Pattern-list)-the given pattern matches 0 times above including 0 times, + (pattern-list)-The given pattern matches 1 times above including 1 times; @ (pattern-list)- The given pattern only matches 1 times;! (pattern-list)-does not match the given pattern in parentheses.
