Description

Currently DFSShell does not support file patterns in dfs file names. It's quite inconvenient for users when they need to manipulate multiple files.

This issue is intended to extend DFSShell to interprete file patterns. A file pattern contains special special pattern matching characters:

?: matches any character
*: matches zero or more characters
[abc]: matches a character from character set

{a, b, c}

[a-c]: matches a character from character range:

{a...c}

[^a]: matches a character not in character set or range

{a}

\c: escape any special meaning of character c
