Question

Wanting to remember some impotant cmds, I used to put them in .bashrc_history file and use search to find, like:

$ history | grep alias | grep coffee | grep code

but sometimes history may lost for some reason. Also, usually several terminals, which may rewrite the history.. So is there any tool to manage?

Answer 1

Put this into your ~/.bashrc and re-login (or source the ~/.bashrc)

prompt_command() {
    history | sed '$!d' >> /path/to/some/file
}

PROMPT_COMMAND=prompt_command

Now every command you type will be appended to /path/to/some/file immediately after you type it
