[NTLUG:Discuss] For the history buffs...what is ":bad option"?

[Chris Cox]

Just for historical raisins...

The #! syntax is relatively new to *ix.  In the ancient days of the
System V vs. BSD scripts which had a "#" as the very first character
were interpreted as csh scripts.  A common technique by Bourne shell
programmers was to use ":" as the first character on their scripts,
":" has other interesting uses vs. "#" as a "comment" delimeter, 
":" lines get evaluated.

Pardon the history...
