|
|
*
|
|
* 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:
|
|
*
|
|
* EX_USAGE -- The command was used incorrectly, e.g., with
|
|
* the wrong number of arguments, a bad flag, a bad
|
|
* syntax in a parameter, or whatever.
|
|
* EX_DATAERR -- The input data was incorrect in some way.
|
|
* This should only be used for user's data & not
|
|
* system files.
|
|
* EX_NOINPUT -- An input file (not a system file) did not
|
|
* exist or was not readable. This could also include
|
|
* errors like "No message" to a mailer (if it cared
|
|
* to catch it).
|
|
* EX_NOUSER -- The user specified did not exist. This might
|
|
* be used for mail addresses or remote logins.
|
|
* EX_NOHOST -- The host specified did not exist. This is used
|
|
* in mail addresses or network requests.
|
|
* EX_UNAVAILABLE -- A service is unavailable. This can occur
|
|
* if a support program or file does not exist. This
|
|
* can also be used as a catchall message when something
|
|
* you wanted to do doesn't work, but you don't know
|
|
* why.
|
|
* EX_SOFTWARE -- An internal software error has been detected.
|
|
* This should be limited to non-operating system related
|
|
* errors as possible.
|
|
* EX_OSERR -- An operating system error has been detected.
|
|
* This is intended to be used for such things as "cannot
|
|
* fork", "cannot create pipe", or the like. It includes
|
|
* things like getuid returning a user that does not
|
|
* exist in the passwd file.
|
|
* EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
|
|
* etc.) does not exist, cannot be opened, or has some
|
|
* sort of error (e.g., syntax error).
|
|
* EX_CANTCREAT -- A (user specified) output file cannot be
|
|
* created.
|
|
* EX_IOERR -- An error occurred while doing I/O on some file.
|
|
* EX_TEMPFAIL -- temporary failure, indicating something that
|
|
* is not really an error. In sendmail, this means
|
|
* that a mailer (e.g.) could not create a connection,
|
|
* and the request should be reattempted later.
|
|
* EX_PROTOCOL -- the remote system returned something that
|
|
* was "not possible" during a protocol exchange.
|
|
* EX_NOPERM -- You did not have sufficient permission to
|
|
* perform the operation. This is not intended for
|
|
* file system problems, which should use NOINPUT or
|
|
* CANTCREAT, but rather for higher level permissions.
