The meaning of the codes is approximately 45 * as follows: 46 * 47 * EX_USAGE -- The command was used incorrectly, e.g., with 48 * the wrong number of arguments, a bad flag, a bad 49 * syntax in a parameter, or whatever. 50 * EX_DATAERR -- The input data was incorrect in some way. 51 * This should only be used for user's data & not 52 * system files. 53 * EX_NOINPUT -- An input file (not a system file) did not 54 * exist or was not readable. This could also include 55 * errors like "No message" to a mailer (if it cared 56 * to catch it). 57 * EX_NOUSER -- The user specified did not exist. This might 58 * be used for mail addresses or remote logins. 59 * EX_NOHOST -- The host specified did not exist. This is used 60 * in mail addresses or network requests. 61 * EX_UNAVAILABLE -- A service is unavailable. This can occur 62 * if a support program or file does not exist. This 63 * can also be used as a catchall message when something 64 * you wanted to do doesn't work, but you don't know 65 * why. 66 * EX_SOFTWARE -- An internal software error has been detected. 67 * This should be limited to non-operating system related 68 * errors as possible. 69 * EX_OSERR -- An operating system error has been detected. 70 * This is intended to be used for such things as "cannot 71 * fork", "cannot create pipe", or the like. It includes 72 * things like getuid returning a user that does not 73 * exist in the passwd file. 74 * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, 75 * etc.) does not exist, cannot be opened, or has some 76 * sort of error (e.g., syntax error). 77 * EX_CANTCREAT -- A (user specified) output file cannot be 78 * created. 79 * EX_IOERR -- An error occurred while doing I/O on some file. 80 * EX_TEMPFAIL -- temporary failure, indicating something that 81 * is not really an error. In sendmail, this means 82 * that a mailer (e.g.) could not create a connection, 83 * and the request should be reattempted later. 84 * EX_PROTOCOL -- the remote system returned something that 85 * was "not possible" during a protocol exchange. 86 * EX_NOPERM -- You did not have sufficient permission to 87 * perform the operation. This is not intended for 88 * file system problems, which should use NOINPUT or 89 * CANTCREAT, but rather for higher level permissions. 90 */ 91 92 #define EX_OK 0 /* successful termination */ 93 94 #define EX__BASE 64 /* base value for error messages */ 95 96 #define EX_USAGE 64 /* command line usage error */ 97 #define EX_DATAERR 65 /* data format error */ 98 #define EX_NOINPUT 66 /* cannot open input */ 99 #define EX_NOUSER 67 /* addressee unknown */ 100 #define EX_NOHOST 68 /* host name unknown */ 101 #define EX_UNAVAILABLE 69 /* service unavailable */ 102 #define EX_SOFTWARE 70 /* internal software error */ 103 #define EX_OSERR 71 /* system error (e.g., can't fork) */ 104 #define EX_OSFILE 72 /* critical OS file missing */ 105 #define EX_CANTCREAT 73 /* can't create (user) output file */ 106 #define EX_IOERR 74 /* input/output error */ 107 #define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ 108 #define EX_PROTOCOL 76 /* remote error in protocol */ 109 #define EX_NOPERM 77 /* permission denied */ 110 #define EX_CONFIG 78 /* configuration error */ 111 112 #define EX__MAX 78 /* maximum listed value */ 113 114 #endif /* sysexits.h */ 115
