:~$ sudo gedit /etc/profile
[sudo] password for Admin: // enter admin password
Then Gedit will open with something like
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -r $i ]; then
. $i
fi
done
unset i
fi
# $$$$$$$$$$$$$$$ copy to here $$$$$$$$$$$$$
Append this to end of the file
PATH=/*$$$$full path to bin here (eg:/home/srinath/myJava/jdk1.6.0_03/bin)$$$$$*/ :${PATH}
export PATH
JAVA_HOME=/*$$$$full path to bin here (eg:/home/srinath/myJava/jdk1.6.0_03/bin)$$$$$*/
export JAVA_HOME
Finally it will look like this.
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -r $i ]; then
. $i
fi
done
unset i
fi
if [ "$PS1" ]; then
if [ "$BASH" ]; then
PS1='\u@\h:\w\$ '
if [ -f /etc/bash.bashrc ]; then
. /etc/bash.bashrc
fi
else
if [ "`id -u`" -eq 0 ]; then
PS1='# '
else
PS1='$ '
