There are too many of these changes to include in this FAQ, but here are some key ones:
a. locations are often different
Note that the last two commands are back in /usr/bin in Solaris 2.5.
b. some old commands don't exist or have replacements
This guide has undergone some changes from 2.0 -> 2.1 and beyond. Several manuals have ended up being combined into this single manual. This manual discusses administrative transition and developer transition issues.
The command "whatnow" (for Solaris 2.x) is included in the "Admigration Toolkit" package (see below). The Admigration toolkit can be obtained from:
Sample output:
% whatnow hostname hostname 4.x command only hostname /usr/ucb/hostname part of SCP package hostname /usr/bin/uname -n alternate command
The whatnow command is limited in that it may point to one command which may only implement a subset of the old command (e.g., pstat points to sar, while pstat -s is identical to swap -s)
