I want to make a system installation
To make a system installation, type
# make systeminstall
AND ALSO use the tcsh_config configuration utility with the -s (--system) option to populate /etc/skel.This installs tcshrc in $(PREFIX)/share/tcshrc/ and adds the tcsh_config configuration utility in $(PREFIX)/bin. The tcsh_config utility can be used to make the installation in the /etc/skel. Finally, tell your users that they can add tcshrc to their existing accounts by running
% tcsh_config --user
 | The tcsh_config configuration utility is usually placed in /usr/local/bin which is not in the path in default Unix installations. You can invoke the utility using the absolute path as in % /usr/local/bin/tcsh_config --user |
