Changing
the PATH
for all users

Introduction
There are many occasions where you want to change environment
variables for all users. Basically there are tweo ways of doing
so: You can change the .profile, .cshrc
and .login files for every user, or
you can change these variables globally for all users. Here we
will discuss the second method. In this example we want to add
/usr/freeware/bin to the PATH
variable for all users. Actually this case is very common, because
when you install the freeware from freeware.sgi.com,
all packages will be installed to this path.
Changing Variables for all users
There are two files that need to be modified: /etc/cshrc
and /etc/profile, they are both executed
for all users at login. The changes for each file are written
in bold letters. Note that this is also the right place for other
changes to the environment. But do not forget the export
statement, or your changes will only affect the script /etc/profile
itself, rather than the whole session.
Changing /etc/profile
#
# /etc/profile - Default settings for all sh users
#
# This script is executed before $HOME/.profile when an
# sh user logs in or invokes /bin/su with the `-' option.
#
# Ignore keyboard interrupts.
trap "" 2 3
case "$0" in
*su )
# Special processing for ``su -'' could go here.
;;
-* )
if [ -z "$ENVONLY" ]
then
# This is a first time login.
#
# Allow the user to break the MOTD only
trap "trap '' 2" 2
cat -s /etc/motd
trap "" 2
# Check for mail.
if /bin/mail -e
then
echo "you have mail"
fi
fi
;;
esac
MSGVERB=text:action
NOMSGLABEL=1
NOMSGSEVERITY=1
export MSGVERB NOMSGLABEL NOMSGSEVERITY
if [$LOGNAME = root]
then
PATH=$PATH:/usr/freeware/bin
else
PATH=$PATH/usr/gnu/bin:/usr/freeware/bin:
fi
MANPATH=/usr/share/catman:/usr/share/man:/usr/catman:/usr/man:
/usr/freeware/catman
export PATH MANPATH
trap 2 3 |
Changing /etc/cshrc
#
# /etc/cshrc - Default settings for all csh users
#
# This is 'sourced' before $HOME/.cshrc, which in turn preceeds
# $HOME/.login when a csh user logs in or invokes /bin/su with
# the `-' option.
# Tell the shell where to look for mail.
if ($?MAIL == 0) setenv MAIL /usr/mail/$USER
set mail=$MAIL
if (! $?ENVONLY) then
# Print the message of the day.
cat -s /etc/motd
# Check for mail.
if ( -e /bin/mail ) then
if ( { /bin/mail -e } ) then
echo 'You have mail.'
endif
endif
endif
setenv MSGVERB text:action
setenv NOMSGLABEL 1
setenv NOMSGSEVERITY 1
if ($USER == "root") then
setenv PATH ${PATH}:/usr/freeware/bin
else
setenv PATH $PATH/usr/gnu/bin:/usr/freeware/bin:
endif
setenv MANPATH /usr/share/catman:/usr/share/man:/usr/catman:/usr/man:
/usr/freeware/catman
