There are four major species of unix sysadmins :
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, and maybe also perl.
2. the administrative fascist :
usually a retentive drone (or rarely, a harridan ex-secretary) who has been forced into system administration.
3. the maniac :
usually an aging cracker who discovered that neither the mossad nor cuba are willing to pay a living wage for computer espionage.
fell into system administration; occasionally approaches major competitors with indesp schemes.
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.
