You can also determine the umask value you want to set by using the following table, which shows the file and directory permissions that are created for each of the octal values of umask.

Table 4-22 Permissions for umask Values

The following line in a user initialization file sets the default file permissions to rw-rw-rw-.

umask 000

Examples of User and Site Initialization Files

The following sections provide examples of user and site initialization files that you can use to start customizing your own initialization files. Many of the examples use system names and paths that you need to change for your particular site.

Example--.profile File

1 PATH=$PATH:$HOME/bin:/usr/local/bin:/usr/ccs/bin:. 
2 MAIL=/var/mail/$LOGNAME 
3 NNTPSERVER=server1 
4 MANPATH=/usr/share/man:/usr/local/man 
5 PRINTER=printer1 
6 umask 022 
7 export PATH MAIL NNTPSERVER MANPATH PRINTER 

1. Defines the user's shell search path.

2. Defines the path to the user's mail file.

3. Defines the user's Usenet news server.

4. Defines the user's search path for man pages.

5. Defines the user's default printer.

6. Sets the user's default file creation permissions.

7. Sets the listed environment variables.

Example--.cshrc File

1 set path=($PATH $HOME/bin /usr/local/bin /usr/ccs/bin)
2 setenv MAIL /var/mail/$LOGNAME 
3 setenv NNTPSERVER server1 
4 setenv PRINTER printer1 
5 alias h history 
6 umask 022 
7 source /net/server2/site-init-files/site.login 

1. Defines the user's shell search path.

2. Defines the path to the user's mail file.

3. Defines the user's Usenet news server.

4. Defines the user's default printer.

5. Creates an alias for the history command. The user will need to type only h to run the history command.

6. Sets the user's default file creation permissions.

7. Sources the site initialization file.

Example--Site Initialization File

The following shows an example site initialization file in which a user can choose a particular version of an application.

# @(#)site.login
main: 
echo "Application Environment Selection"
echo ""
echo "1. Application, Version 1"
echo "2. Application, Version 2"
echo "" 
echo -n "Type 1 or 2 and press Return to set your 
application environment: " 

set choice = $<	

if ( $choice !~ [1-2] ) then 
goto main 
endif 

switch ($choice) 

case "1": 
setenv APPHOME /opt/app-v.1 
breaksw 

case "2": 
setenv APPHOME /opt/app-v.2 
endsw

This site initialization file could be referenced in a user's .cshrc file (C shell users only) with the following line:

source /net/server2/site-init-files/site.login

In this line, the site initialization file is named site.login and is located on a server named server2. This line also assumes that the automounter is running on the user's system.
