Programmer ninjas of the past used these tricks to sharpen the mind of code maintainers.
Code review gurus look for them in test tasks.
Novice developers sometimes use them even better than programmer ninjas.
Read them carefully and find out who you are – a ninja, a novice, or maybe a code reviewer?
As in sysexits.h
, but in a (sometimes) more accessible place. Formatted painlessly in Vim
According to style(9)
, it is not a good practice to call exit(3)
with arbitrary values to indicate a failure condition when ending a program. Instead, the pre-defined exit codes from sysexits
should be used, so the caller of the process can get a rough estimation about the failure class without looking up the source code.
The successful exit is always indicated by a status of 0
, or EX_OK
. Error numbers begin at EX__BASE
to reduce the possibility of clashing with other exit statuses that random programs may already return. The meaning of the codes is approximately as follows:
Exit Code | Description |

<div id="drag" draggable="true" ondragstart="event.dataTransfer.setData('text/plain', null)"> | |
