How to stop zsh from printing out command

Question

just setup zsh with oh-my-zsh on Raspberry Pi

After every command, it reprints the command I typed. For example...

pi@raspberrypi ~>> ls

;lsDesktop ocr_pi.png python_games

Two causes of stuff like this are:

1. (most likely) You have something in a command execution hook causing this. See this for details http://zsh.sourceforge.net/Doc/Release/Functions.html#Hook-Functions

try

which precmd
which preexec
which zshaddhistory

or if they did it using the arrays to hold hooks:

echo $precmd_functions
echo $preexec_functions
echo $zshaddhistory_functions

or any of the hooks described in that page with '_functions' appended to it.

There is likely some buggy function bound to get executed right before you run a command or when you save your history etc. To turn them off (other than fixing oh-my-zsh or your setup of it) Call unset precmd_functions to unset an array of functions, or unfunction precmd.

2. (very unlikely) you may have something funny getting executed in your prompt (unlikely but possible). Try export PROMPT='foo ' or unsetting PS1.
