hey, iam extremly sorry for giving u trouble,
as u said i set the environment....
this is the outcome after that
[BTIS@WORKSTATION3 ~]$ env | grep -i http_proxy
http_proxy=http://asomavarapu@xxxxxxxxxxxxx:dbsa121@10.100.15.3:8080
HTTP_PROXY=http://asomavarapu@xxxxxxxxxxxxx:dbsa121@10.100.15.3:8080
[BTIS@WORKSTATION3 ~]$
and this is the file of .bash_profile that i edited
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
export http_proxy="http://asomavarapu@xxxxxxxxxxxxx:dbsa121@10.100.15.3:8080
"
export HTTP_PROXY="http://asomavarapu@xxxxxxxxxxxxx:dbsa121@10.100.15.3:8080
"
