I just checked the draft of the next revision of the POSIX spec and can
find no reference to 125 being either recommended or required as the status
for general exec failures. For example, the spec for xargs includes this:
EXIT STATUS
The following exit values shall be returned:
0 All invocations of utility returned exit
status zero.
1-125 A command line meeting the specified
requirements could
not be assembled, one or more of the
invocations of utility
returned a non-zero exit status, or some
other error occurred.
126 The utility specified by utility was found but
could not be invoked.
127 The utility specified by utility could not be
found.
I'm confident that this isn't a change from previous versions. Where is
this proposed use of 125 documented?
