Exit status

 | Computers and stuff | 0 Comments

A small integer value returned to the parent process when a child process completes. It is an 8-bit value that, for historical reasons, is further limited to the range 0 through 125, with values 126 through 255 assigned special meaning for abnormal process completion. Conventionally, a zero exit status means success, and a non-zero value, some sort of failure.
