Hiding command from history

Hiding command from history

[İsmail Dönmez]

Hi,

I know I can set HIST_IGNORE_SPACE and any command starting with space
will not be logged in history. But with that I have many aliases like

alias ls=" ls"
alias mv=" mv"

etc. So, I wonder if there is an easier way to blacklist multiple
commands from history without creating an alias for each of them?

Thanks!

Have a look at HISTORY_IGNORE in the zshparam manule, and if you want
something a bit more powerful also the zshaddhistory hook in the zshmisc
manuel (and let us know if that doesn't seem to make sense...)

This seems to be the best option but I can't figure out the syntaxt.
Bash's similar HISTIGNORE syntax

HISTORY_IGNORE="rm *:ls *"

doesn't seem to work. Tried with

> HISTORY_IGNORE="rm *:ls *" zsh

Thanks!

HISTORY_IGNORE just stops things being written to history files;
I don't think that's quite you want.  If it was, it's a single pattern,
so you should be able to do

HISTORY_IGNORE="(rm|ls) *"

You can do this, though:

zshaddhistory() { [[ $1 = (ls|rm)\ * ]] && return 1; }

and indeed there's no reason I can think of why you couldn't simply
define

zshaddhistory() { [[ $1 = ${~HISTORY_IGNORE} ]] && return 1; }

Talked too early it seems. When I add this line to my ~/.zshrc then
history file is never updated when I exit the shell. Removing this
line fixes the problem. Any ideas why? I also tried the

zshaddhistory() { [[ $1 = (ls|rm)\ * ]] && return 1; }

version but the same problem happens there. I am using zsh.git

Sorry, I was careless with status.  Which just goes to show...

See if the following works, which I think it does...

zshaddhistory() { [[ $1 != ${~HISTORY_IGNORE} ]]; }

The old one reflected the status of the [[ ... ]] if it failed, but the
status of that is actually all we need as long as we reverse it.

That works as expected, thanks again!

Hey, I misspelled manual twice in two different ways.

Pretend I didn't.

Ok, from now on all typographical errors will be blamed on Manuel.
