For example, say I do a command like appbuild by hitting up arrow ten times in a row. Now, if I want to go back to the last unique command before that, I have to hit up ten times in a row.

Any way to change this preference? IIRC Bash did not do this.

I think you're looking for setopt hist_ignore_dups. The equivalent bash setting was HISTCONTROL=ignoredups:…. If you had HISTCONTROL=erasedups, the zsh equivalent is setopt hist_ignore_all_dups.

On a related note, the zsh equivalent to putting ignorespace in HISTCONTROL is setopt hist_ignore_space.

setopt commands, like other interactive configurations for zsh, go into ~/.zshrc (i.e. the file called .zshrc in your home directory).
