how to clear command history

hi
Any one can help me. I am using Sun_Solaris. The command history set to 100 at .cshrc. I am unable to clear the command histoy. In Linux it is very easy by giving command
history -c
I could not find any such type command to clear the history.
Is there any such type of command for solaris. pl help.

i dont know how to directory kill the file but you can run

# set history=0

and this will prevent any history capture as well as keep someone from display your history from previous commands (or previous history lists).

`history -c` is a bash function and not a linux os function. if you move to bash, you can clear your history as usual. i can do this on solaris without issue.

dear pupp
u have given the command
# set history =0
will not save any command history. actually i want like bash function that is
# history -c which delete the existing history.
i want to know any such command in csh.
if any such command or any other method available in csh.

All you need to do is remove the file identified by $histfile in csh.
