UUOC (from comp.unix.shell on [[Usenet]]) stands for "Useless Use of cat"; the reference is to the [[Unix]] command [[cat]](1), not the [[Panthera|feline]] animal. As received wisdom on comp.unix.shell observes, "The purpose of cat is to concatenate (or 'catenate') files. If it's only one file, concatenating it with nothing at all is a waste of time, and costs you a process." Nevertheless one sees people doing |
|||
cat file | some_command and its args ... |
|||
instead of the equivalent and cheaper |
|||
<file some_command and its args ... |
|||
from [[Wikipedia:Cat (Unix)]] |
