Command history

Hello everyone,
first of all user google: echo "" > .sh_history
i tried your suggested command and yes it does overwrite the .sh_history file with a line. But when i use the command history, it still shows me all of my commands!!! I want to delete the history of commands. Can you suggest something on that?
Second of all user tikul: export HISTSIZE=100
yes i wrote that in my .profile file but i still get 500+ commands! Can you comment on that?
And finally Mr. Hedensk
you asked me to dump my command history with 'history' command. It didn't work as expected. What exactly should i do here?
Now this is very likely possible that i might have misunderstood you all and didn't do it as it is supposed to be done. But can you all please try and point out my mistake or a possible explanation for it
. Thank you all and have a good one

The userdel command modifies the system account files, deleting all entries that refer to login. The named user must exist. The options which apply to the userdel command are: -r Files in the user's home directory will be removed along with the home directory itself and the user's mail spool. Files located in other file systems will have to be searched for and deleted manually. FILES
