Stopping zsh from clearing the screen on each command

Question

I use zsh on Mac OS X, with a theme based on "oh-my-zsh".

Each time I run a command, zsh "clears" the screen (really, inserting a few dozens newlines). This is very irritating, but I can't figure out how to turn this off.

What am I missing?

Answer 1

As mentioned in the comments, commenting out the following from ~/.oh-my-zsh/lib/alias.zsh will fix the problem:

alias history='fc -l 1'

Answer 2

I have had similar troubles and found a solution by setting the TERM variable in my .zshrc file as so:

if [ `find /usr/share/terminfo -name "xterm-256color" -print` &> /dev/null ]; then
    export TERM='xterm-256color'
else
    export TERM='xterm'
fi

(No comment about using xterm over rxvt)
