UNIX for Dummies Questions & Answers

Hello everyone,
I am aware about the history command we use in bash. Just had a question regarding the history of commands. Is there any way i can limit my commands to be remembered or is there any way to delete the commands used by myself? Thank you

There is a file in your home directory called .sh_history. To clear your history, just empty this file

From your home directory:

echo "" > .sh_history

You can also limit the size of your history file (in KSH) by setting the HISTFILE variable. See this thread

To limit the history file in last 100 commands. Put the follows in your profile.
export HISTSIZE=100

also you can dump your cammand history to stdout with the
'history'
command.

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

well what i ment by 'dump' was that it would output its contents to your screen. not empty the history.

O ok i got that norsk Thanks
