Customizing User Environments

This section describes how to determine which initialization files you can edit to customize the local environment based on your choice of login shell, and where to find them in the SunOS release 5.7 file systems. Set up your environment by editing the variables in the initialization files. The default shell determines which files you need to edit: .profile, .login, or .cshrc. Table 6-2 shows the initialization files for the Bourne, C, and Korn shells.

Table 6-2 Initialization Files for Bourne, C, and Korn Shells

Shell	Initialization File	Purpose
Bourne	/etc/profile	Defines system profile at login
	$HOME/.profile	Defines user's profile at login
C	/etc/.login	Defines system environment at login
	$HOME/.cshrc	Defines user's environment at login
	$HOME/.login	Defines user's profile at login
Korn	/etc/profile	Defines system profile at login
	$HOME/.profile	Defines user's profile at login
	$HOME/ksh_env	Defines user's environment at login in the file specified by the ksh_env variable

In this release, the shell initialization-file templates have moved to the /etc/skel directory from /usr/lib, where they were in the SunOS release 4 software. The template file locations are shown in Table 6-3. Copy the template file (or files) for the appropriate default shell to your home directory before you modify it.

Shell	File
Bourne	/etc/skel/local.profile
C	/etc/skel/local.login /etc/skel/local.cshrc
Korn	/etc/skel/local.profile

Using the SunOS Release 4 Work Environment With the Solaris Software

The SunOS release 5.7 software can use the old SunOS release 4 system files and initialization files such as .login, .cshrc, and.profile to re-create the look and feel of the SunOS release 4 work environment. Many of these SunOS release 4 files can be converted, or used as they are, and executed easily.

The installation process in Chapter 3, Converting a SunOS Release 4 System to the Solaris 7 Environment, explains how to re-create the SunOS release 4 environment within the Solaris 7 operating environment.
