Seems like history [number] is backward in zshell because it's using fc. How do I get history [number] to behave like it does in bash?

➜  exec bash
bash-3.2$ history 3
   35  history 5
   36  exit
   37  history 3
bash-3.2$ 

➜ history 3
    1  pwd
    2  ..
    3  mv work Documents

➜ history
   3133  history 5
   3134  exec bash
   3135  history
   3136  history 3
   3137  history -3
   3138  history 20

So in bash it behaves like I'd expect: last 3 commands. But in zshell it's backwards: the first 3 history commands. This is annoying and I'd like to fix it.

Closest I've got so far:

function history {
  fc -l -$1
}

But that still produces history starting at 1 instead of the last entry.

  • I don't use zsh, but.. alias history='history | tail -n${1-10}'?

It wasn't as difficult as I thought it would be. Added this to my ~/.profile

# zshell aliases history to "fc -l"

# quick version
alias h="fc -l -50"     # last 50

# history searching
function hg {
  echo "Searching for '$1'..."
  fc -l 0 | grep "$1"
}

Looks like bash has it backwards, so if you flip the sign on the number...

$ PS1='%% ' zsh -f
% echo blah
blah
% echo de
de
% echo blah
blah
% history() { num=$(( -1 * $1 )); builtin history $num }
% history 3
    2  echo de
    3  echo blah
    4  history() { num=$(( -1 * $1 )); builtin history $num }
%

  • Uhh: history 3 | wc -l --> 3176; that's what I get when I run your first 2 lines.

  • Probably oh-my-zsh bringing the usual derp. What happens under zsh -f with some history added?
