|
# sysexits.sh -- Exit status codes for system programs.
|
||
|
|
#
|
||
|
|
# This include file attempts to categorize possible error
|
||
|
|
# exit statuses for system programs, notably delivermail
|
||
|
|
# and the Berkeley network.
|
||
|
|
#
|
||
|
|
# Error numbers begin at EX__BASE to reduce the possibility of
|
||
|
|
# clashing with other exit statuses that random programs may
|
||
|
|
# already return. The meaning of the codes is approximately
|
||
|
|
# as follows:
|
||
|
|
#
|
||
|
|
# EX_USAGE -- The command was used incorrectly, e.g., with
|
||
|
|
# the wrong number of arguments, a bad flag, a bad
|
||
|
|
# syntax in a parameter, or whatever.
|
||
|
|
# EX_DATAERR -- The input data was incorrect in some way.
|
||
|
|
# This should only be used for user's data & not
|
||
|
|
# system files.
|
||
|
|
# EX_NOINPUT -- An input file (not a system file) did not
|
||
|
|
# exist or was not readable. This could also include
|
||
|
|
# errors like "No message" to a mailer (if it cared
|
||
|
|
# to catch it).
|
||
|
|
# EX_NOUSER -- The user specified did not exist. This might
|
||
|
|
# be used for mail addresses or remote logins.
|
||
|
|
# EX_NOHOST -- The host specified did not exist. This is used
|
||
|
|
# in mail addresses or network requests.
|
||
|
|
# EX_UNAVAILABLE -- A service is unavailable. This can occur
|
||
|
|
# if a support program or file does not exist. This
|
||
|
|
# can also be used as a catchall message when something
|
||
|
|
# you wanted to do doesn't work, but you don't know
|
||
|
|
# why.
|
||
|
|
# EX_SOFTWARE -- An internal software error has been detected.
|
||
|
|
# This should be limited to non-operating system related
|
||
|
|
# errors as possible.
|
||
|
|
# EX_OSERR -- An operating system error has been detected.
|
||
|
|
# This is intended to be used for such things as "cannot
|
||
|
|
# fork", "cannot create pipe", or the like. It includes
|
||
|
|
# things like getuid returning a user that does not
|
||
|
|
# exist in the passwd file.
|
||
|
|
# EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
|
||
|
|
# etc.) does not exist, cannot be opened, or has some
|
||
|
|
# sort of error (e.g., syntax error).
|
||
|
|
# EX_CANTCREAT -- A (user specified) output file cannot be
|
||
|
|
# created.
|
||
|
|
# EX_IOERR -- An error occurred while doing I/O on some file.
|
||
|
|
# EX_TEMPFAIL -- temporary failure, indicating something that
|
||
|
|
# is not really an error. In sendmail, this means
|
||
|
|
# that a mailer (e.g.) could not create a connection,
|
||
|
|
# and the request should be reattempted later.
|
||
|
|
# EX_PROTOCOL -- the remote system returned something that
|
||
|
|
# was "not possible" during a protocol exchange.
|
||
|
|
# EX_NOPERM -- You did not have sufficient permission to
|
||
|
|
# perform the operation. This is not intended for
|
||
|
|
# file system problems, which should use NOINPUT or
|
||
|
|
# CANTCREAT, but rather for higher level permissions.
