How to erase duplicates of commands from the command history ?
 

Hello Friends,

This is the configuration that i have done in my bash profile to erase the duplicate linux commands :

HISTCONROL=ignoredups:erasedups
export HISTCONTROL
Still, i am finding duplicates of commands (some are appearing 2 times, some are appearing 3 times and so on....)

Can anyone suggest me how to erase / prevent duplicates from the command history ?

do you find them after you log out and back in again ?
or
during the same terminal or user session ?

Actually, to be sorry at the 1st place, there is a typo in the command that i have written
in the .bash_profile. Now, i have rectified that error and its working fine. !!
