Using the Reference Table

• If an interface is listed as changed (C), a brief description of differences between SunOS release 4 command and the Solaris 7 command is provided.

• If an interface is listed as the same (S), the Solaris 7 interface supports all features of the SunOS release 4 interface. In some cases the interface has been enhanced, but can be considered a complete superset of the SunOS release 4 interface.

• If an interface has an alternative (A), check the Notes section for its replacement.

• If an interface is listed as not available (N), check the Notes section for information about its replacement. Replacement commands, when available, are also shown in the SunOS release 5.7 column.

---

Note -

The SunOS release 5.7 directory structure is different than the SunOS release 4 structure; some commands behave the same, but have a different path name. For example, the SunOS release 4 /usr/etc/newfs command now resides in /usr/sbin/newfs, but the interface has not changed. This command, and others like it, are considered the same (S) according to this table's guidelines.

---

Commands that exist in both /usr/bin and /usr/5bin have two table entries, the first documents the /usr/bin command, and the second entry documents the /usr/5bin command.

For complete information on all Solaris 7 interfaces, see man Pages(1): User Commands.

Examples

Table A-1 through Table A-4 show sample table entries and are followed by an interpretation

Table A-1 Table Entry Example 1

SunOS release 4 Command	SunOS release 5.7 Status	Alternative Available and Notes	BSD
fasthalt (8)	A	The init 0 command provides similar capabilities	S

The fasthalt command is not available in the Solaris 7 base release. This command is available if you install the SunOS/BSD Compatibility package on your system. The init 0 command replaces fasthalt. If you use the compatibility package fasthalt command in scripts or applications, they will not work on other SVR4 systems. Compatibility package commands can be found in /usr/ucb on systems that have this package installed, and they are documented in section 1B of man Pages(1): User Commands; for example, fasthalt (1B).

Table A-2 Table Entry Example 2

SunOS release 4 Command	SunOS release 5.7 Status	Alternative Available and Notes	BSD
cc (1V)	N	The C compiler is only available with the C language unbundled tools.	C

The C compiler is not available in the SunOS release 5.7 software. A C compiler is available with the SunOS/BSD Compatibility package, but it requires the unbundled C compiler and does not provide the same interface and output as the SunOS release 4 compiler.

Table A-3 Table Entry Example 3

SunOS release 4 Command	SunOS release 5.7 Status	Alternative Available and Notes	BSD
date (1V) -- SysV	S		N
date (1V)	C	The format used when setting the date is slightly different in SunOS release 5.7. See the date(1) man page for more information.	N

The SunOS release 4 software had two date commands: /usr/5bin/date (compared in the SysV entry) and /usr/bin/date (compared in the second entry). The /usr/5bin/date command is identical to the SunOS release 5.7 command. If you had /usr/5bin in your path before /usr/bin, you will not notice any difference in this command in the SunOS release 5.7 software. If you are accustomed to using the SunOS release 4 /usr/bin/date command, you should look at the SunOS release 5.7 date (1) man page before attempting to set the date on your system.

Table A-4 Table Entry Example 4

SunOS release 4 Command	SunOS release 5.7 Status	Alternative Available and Notes	BSD
rev (1)	N		N

The SunOS 4.2 rev command is not available in the SunOS release 5.7 software or the BSD release. There is no replacement command available.
