command stack in buffer

[vijay shanker]

Hi all,

I hope many of you must be aware of this.

When i use a terminal to execute my commands. Some times i need to execute
same command multiple times. So, if i want to choose a previously executed
command, It makes me very tired to choose from history of command.

So , instead of choosing I prefer to go and write it again. But i was
thinking if there existing any thing that can remove duplicates form
the command history?

Regards,
