26: .IP \(bu 3
27: The \fIbad144\fP program
28: can now be used to add new bad sectors to the bad sector file.
29: Replacement sectors are rearranged as needed to sort the new sectors
30: into the bad sector list.
31: Reformat operations to mark bad sectors
32: to the bad sector table should still be done only
33: with the system running single user.
34: .IP \(bu 3
35: \fIGetty\fP's description file, \fI/etc/gettytab\fP, now describes what
36: program should be run in addition to the other information that
37: it used to include.
38: .sp
39: .PP
40: .BP arff

46: Resolution Protocol tables.

50: It verifies that the file is properly sorted.
51: Verbose and no-write options allow dry runs.
52: .BP catman
53: Now allows a list of manual directories. Links are properly set up so
54: that the manual source need not be kept on line on all machines.

57: are left around but they are deleted if the user-id no longer exists.
58: .BP chown
59: Was modified to be recursive.
60: \fIChown\fP accepts an \fIowner.group\fP syntax
61: to change owner and group simultaneously.

87: .BP dump
88: When dumping at 6250 bpi, the tape is written in 32Kb records instead
89: of 10Kb records.
90: Efforts have been made to improve the consistency of dumps made
91: on active file systems (though the practice is still NOT recommended).
92: The Caltech streaming dump modifications using a ring of slave
93: processes have been incorporated.
94: .I Dump

103: \fIFsck\fP has been sped up considerably by eliminating one of
104: the two passes across the inodes.
105: It has also been taught to create and grow directories
106: so that it can now rebuild the root of a file system
107: as well as create and enlarge the \fIlost+found\fP
108: directory as necessary.
109: .BP ftpd
110: Among the new facilities supported by the FTP server are:
111: the ABOR command for transfer abort,
112: the PASV command for third party transfers,
113: and the new RFC959 FTP commands (such as STOU, ``store unique'').
114: \fIFtpd\fP now uses \fIsyslog\fP to log errors, and is invoked by \fIinetd\fP.
115: .BP gettable
116: Now has a flag for checking the version without retrieving the whole host table.

150: \fBup\fP command reverses the effect of the \fBdown\fP command. The
151: \fBstatus\fP command now displays the contents of the print queue in
152: addition to the status of the daemon process. The \fBclean\fP command
153: does a better job of removing incomplete queue entries.
154: .BP lpd
155: A new capability, \fBhl\fP, may be used to print a job's banner after

161: that \fI/dev/printer\fP can be automatically removed. Symbolic
162: links to spool files are now checked carefully to close a
163: security hole. All printing parameters are now
164: properly reset for each job. Remote spooling connections
165: now time out if the server crashes. Errors in spooling

177: A new program to rebuild the \fI/etc/passwd\fP dbm database.
178: .BP mount
179: Better error messages are returned when \fImount\fP fails.
180: When checking \fI/etc/fstab\fP to find the device name of a file system
181: when only the mount point is specified,
182: it also checks the \fItype\fP field to insure that the entry
183: is \fBrw\fP, \fBro\fP, or \fBrq\fP.
184: .BP named
185: Is a new program implementing the Internet domain naming system.
186: It is used to perform hostname and

191: Supports new options to
192: .I mkfs .
193: .BP pac
194: Has a new option, \fB\-m\fP, to cause machine names to be disregarded

196: taken from the printer description if it is not specified on the command line
197: with the \fB\-p\fP option.
198: .BP ping
199: Is a new program for sending ICMP echo requests.
200: .BP pstat
201: Can handle kernel crash dumps and new terminal multiplexers. Core dumps
202: should be less frequent.
203: .BP repquota
204: Only prints entries for users that have files (or blocks) allocated.
205: .BP restore
206: The interactive mode of \fIrestore\fP now understands globbing.
207: Interrupting interactive mode returns to the prompt.
208: A new input path name may be specified on each volume change.

212: Now runs under
213: .I inetd .

237: .I inetd .
238: The address is passed through if the host name for the address
239: cannot be determined.

267: all jobs in the queue will be run in one process,
268: with host statuses cached;
269: this uses more memory but generally improves performance.
270: The job priority now includes creation time
271: and number of recipients
272: (the
273: .B y
274: option)
275: as well as the message size
276: (the
277: .B q
278: option)
279: and the job precedence
280: (the
281: .B z
282: option);
283: this priority is modified by the
284: .B Z
285: option whenever it fails to complete.
286: No attempt is made to run large jobs
287: if the load average is too high.
288: .IP
289: The
290: .B $[
291: \&...
292: .B $]
293: syntax can be used on the RHS of a rewriting rule
294: to canonicalize a host name using \fIgethostbyname\fP.
295: This is especially useful when running the version
296: of \fIgethostbyname\fP that calls the name server.
297: .IP

313: is settable by the
314: .B B
