对于目录,通常使用前几个字母作为缩写:
bin BINaries
dev DEVices
etc ETCetera
lib LIBrary
var VARiable
proc PROCesses

这种缩写的其它情况
diff DIFFerences
cal CALendar
cat CATenate

如果某种缩写比较深入人心,例如“mesg”代表“message”,在新的复合缩写中,将沿用这种缩写方式

定义中包含自身缩写,如 GNU:
GNU's Not Unix
使用这个定义来解释定义中的缩写:
(GNU's Not Unix)'s Not Unix
这意味着它是可以无限递归的:
(((((GNU's Not Unix)'s Not Unix)'s Not Unix)'s Not Unix)'s Not Unix)'s Not Unix ……
