The Four Major Species of Unix Sysadmin:

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.
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, morphodite, or old COBOL programmer selected to be the system administrator by a committee of cretins, morphodites, and old COBOL programmers.
