38 * SYSEXITS.H -- Exit status codes for system programs.
39 *
40 * This include file attempts to categorize possible error
41 * exit statuses for system programs, notably delivermail
42 * and the Berkeley network.
43 *
44 * Error numbers begin at EX__BASE to reduce the possibility of
45 * clashing with other exit statuses that random programs may
46 * already return. The meaning of the codes is approximately
47 * as follows:
48 *
49 * EX_USAGE -- The command was used incorrectly, e.g., with
50 * the wrong number of arguments, a bad flag, a bad
51 * syntax in a parameter, or whatever.
52 * EX_DATAERR -- The input data was incorrect in some way.
53 * This should only be used for user's data & not
54 * system files.
55 * EX_NOINPUT -- An input file (not a system file) did not
56 * exist or was not readable. This could also include
57 * errors like "No message" to a mailer (if it cared
58 * to catch it).
59 * EX_NOUSER -- The user specified did not exist. This might
60 * be used for mail addresses or remote logins.
61 * EX_NOHOST -- The host specified did not exist. This is used
62 * in mail addresses or network requests.
63 * EX_UNAVAILABLE -- A service is unavailable. This can occur
64 * if a support program or file does not exist. This
65 * can also be used as a catchall message when something
66 * you wanted to do doesn't work, but you don't know
67 * why.
68 * EX_SOFTWARE -- An internal software error has been detected.
69 * This should be limited to non-operating system related
70 * errors as possible.
71 * EX_OSERR -- An operating system error has been detected.
72 * This is intended to be used for such things as "cannot
73 * fork", "cannot create pipe", or the like. It includes
74 * things like getuid returning a user that does not
75 * exist in the passwd file.
76 * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
77 * etc.) does not exist, cannot be opened, or has some
78 * sort of error (e.g., syntax error).
79 * EX_CANTCREAT -- A (user specified) output file cannot be
80 * created.
81 * EX_IOERR -- An error occurred while doing I/O on some file.
82 * EX_TEMPFAIL -- temporary failure, indicating something that
83 * is not really an error. In sendmail, this means
84 * that a mailer (e.g.) could not create a connection,
85 * and the request should be reattempted later.
86 * EX_PROTOCOL -- the remote system returned something that
87 * was "not possible" during a protocol exchange.
88 * EX_NOPERM -- You did not have sufficient permission to
89 * perform the operation. This is not intended for
90 * file system problems, which should use NOINPUT or
91 * CANTCREAT, but rather for higher level permissions.
