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