| 36 | * SYSEXITS.H -- Exit status codes for system programs. |
| 37 | * |
| 38 | * This include file attempts to categorize possible error |
| 39 | * exit statuses for system programs, notably delivermail |
| 40 | * and the Berkeley network. |
| 41 | * |
| 42 | * Error numbers begin at EX__BASE to reduce the possibility of |
| 43 | * clashing with other exit statuses that random programs may |
| 44 | * already return. 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. |
