#  SYSEXITS.SH -- Exit status codes for system programs.
#
#  This include file attempts to categorize possible error
#  exit statuses for system programs, notably delivermail
#  and the Berkeley network.
#
#  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.
