I want to prevent users from doing spesific command "history -c" or "history" in general
How can I do ?

For such a specific feature, you can set the HISTSIZE variable to 0 and the mark it read-only. Do this in the global initialization (rc) file.

Code:

export HISTSIZE=0
declare -r HISTSIZE

Note, a clever user can still get around this.

THis's v good, But what if I want to just prevent users from usind -c with there history command ??

As far as I know there is no way of preventing a user from deleting their history in bash.

Okay, you can re-compile bash or what have you and disable the history command. You "simply" search the source for the word "history" until you find a C-string, go into this file, and basically, remove the string or line(s) of code which links the keyword to a function. Then recompile and re-install.
