Installation guide

• General-purpose commands

Commands for searching ﬁles (such as grep), listing directory contents

and moving between directories (ls, cd, and pwd), displaying the date

and time (date), and so on are, in most cases, the same as the ULTRIX

equivalent commands. Differences are noted in Appendix A. The ps

command functions in either of the following two ways:

– If you omit the minus sign before the option keywords (for example,

ps x), the command functions like the BSD ps command.

– If you include the minus sign (for example, ps -x), the command

functions like the System V ps command.

The two versions have different lists of options; see ps

(1).

• Mail

DIGITAL UNIX mail commands are the same as their ULTRIX

equivalents except that the command names are different. The mail

command on an ULTRIX system invokes /usr/ucb/mail (the Mail

user agent). To use this mail handler on a DIGITAL UNIX system,

enter the Mail or the mailx command. The DIGITAL UNIX user

interface for the mailx user agent is slightly different from that of the

ULTRIX version. The mail command on a DIGITAL UNIX system

invokes the /bin/mail program (the binmail user agent). You can use

the Message Handler Utility (MH) just as you use MH on an ULTRIX

system, with the exception that the DIGITAL UNIX MH utility does not

support bulletin boards. For information about using the binmail and

mailx commands and the MH utility, see binmail

(1), mailx(1), and

(1).

The DECwindows Mail program on DIGITAL UNIX workstations has a

user interface based on Motif, and is similar to the DECwindows Mail

program on ULTRIX workstations. For information on other differences

and on using DECwindows Mail, see dxmail

(1X).

• Notepad

The Notepad program on DIGITAL UNIX workstations has a user

interface based on Motif, and is similar to the one on ULTRIX

workstations. For information about using the Notepad program, see

dxnotepad

(1X) or start the Notepad program and read its online help

information.

• Paint

The Paint program on DIGITAL UNIX workstations has a user interface

based on Motif, and is similar to the one on ULTRIX workstations.
