unsetting a part of ENV variable
 

Dear friends !

My PATH variable contains so many paths.I want to remove Particular path from it , because I entered it wrong.
exa: PATH:/usr/bin: /usr/sbin/:/root/:etc....,Now I want to remove" /usr/bin" from it

How to do ?

Your initial path is set in /etc/profile but you can over write it anywhere.

How did you set your extra path directories? In ~/.profile or ~/.bash_profile?

If you want to completely rewrite it just enter
export PATH=/sbin:/usr/sbin:/usr/local/sbin:/root/bin:/usr/local/bin:/usr/bin:/usr/X11R6/bin:/bin:/usr/games:/opt/gnome/bin:/opt/kde3/bin:/usr/lib/java/jre/bin

or whatever you want it to be in your ~/.profile or ~/.bash_profile

unset
 

I added ay command prompt

$PATH=$PATH:\ALL PATHS

That shud be good just for this login session. Log out and in again and see if you get the defaults
