There are four major species of Unix sysad:
1.The TECHNICAL THUG. Usually a systems programmer who has been forced into system administration; writes scripts in a polyglot of the Bourne shell, sed, C, awk, perl, and APL.

4.The IDIOT. Usually a cretin, morpohodite, or old COBOL programmer selected to be the system administrator by a committee of cretins, morphodites, and old COBOL programmers.
