PROFILE ( 4) PROFILE ( 4)
NAME profile - setting up an environment at login time
DESCRIPTION
If your login directory contains a file named .profile, that file will
be executed (via the shell's exec .profile) before your session
begins; .profiles are handy for setting exported environment variables
and terminal modes. If the file /etc/profile exists, it will
be executed for every user before the .profile. The following
example is typical (except for the comments):
# Make some environment variables global
export MAll.. PATH TERM
# Set file creation mask
umask 22
# Tell me when new mail comes in
MAIL=/usr/mail/myname
# Add my /bin directory to the shell search sequence
P ATH=$PATH:$HOME/bin
# Set terminal type
echo "terminal: \c"
read TERM
case $TERM in

BUGS
On the UNIX PC the profile file is often manipulated by user-level
Administration functions performed through the Office. Haphazard
modification by the user of /etc/profile can thoroughly confuse
this set of functions.
