61 * SYSEXITS.H -- Exit status codes for system programs.
62 *
63 * This include file attempts to categorize possible error
64 * exit statuses for system programs, notably delivermail
65 * and the Berkeley network.
66 *
67 * Error numbers begin at EX__BASE to reduce the possibility of
68 * clashing with other exit statuses that random programs may
69 * already return. The meaning of the codes is approximately
70 * as follows:
71 *
72 * EX_USAGE -- The command was used incorrectly, e.g., with
73 * the wrong number of arguments, a bad flag, a bad
74 * syntax in a parameter, or whatever.
75 * EX_DATAERR -- The input data was incorrect in some way.
76 * This should only be used for user's data & not
77 * system files.
78 * EX_NOINPUT -- An input file (not a system file) did not
79 * exist or was not readable. This could also include
80 * errors like "No message" to a mailer (if it cared
81 * to catch it).
82 * EX_NOUSER -- The user specified did not exist. This might
83 * be used for mail addresses or remote logins.
84 * EX_NOHOST -- The host specified did not exist. This is used
85 * in mail addresses or network requests.
86 * EX_UNAVAILABLE -- A service is unavailable. This can occur
87 * if a support program or file does not exist. This
88 * can also be used as a catchall message when something
89 * you wanted to do doesn't work, but you don't know
90 * why.
91 * EX_SOFTWARE -- An internal software error has been detected.
92 * This should be limited to non-operating system related
93 * errors as possible.
94 * EX_OSERR -- An operating system error has been detected.
95 * This is intended to be used for such things as "cannot
96 * fork", "cannot create pipe", or the like. It includes
97 * things like getuid returning a user that does not
98 * exist in the passwd file.
99 * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
100 * etc.) does not exist, cannot be opened, or has some
101 * sort of error (e.g., syntax error).
102 * EX_CANTCREAT -- A (user specified) output file cannot be
103 * created.
104 * EX_IOERR -- An error occurred while doing I/O on some file.
105 * EX_TEMPFAIL -- temporary failure, indicating something that
106 * is not really an error. In sendmail, this means
107 * that a mailer (e.g.) could not create a connection,
108 * and the request should be reattempted later.
109 * EX_PROTOCOL -- the remote system returned something that
110 * was "not possible" during a protocol exchange.
111 * EX_NOPERM -- You did not have sufficient permission to
112 * perform the operation. This is not intended for
113 * file system problems, which should use NOINPUT or
114 * CANTCREAT, but rather for higher level permissions.
