Wildcards

Always seeking to emulate MSDOS, Unix provides filename wildcard characters too!

Tokens:

• ?: any single character
• *: zero or more characters
• []: character list
• {opt1,opt2}: ``brace expansion''
• all other characters are literal

eg1$ rm -f .[a-zA-Z0-9]*
eg2$ ls -l [!A-Z]*
eg3$ mkdir -p /usr/local/{bin,src,share,info}
