My .zshrc was executed twice

[NichtsHsu]

Recently when I use diff it always complains that color-diff:1: maximum nested function level reached; increase FUNCNEST?. And which color-diff gave me:

$ which color-diff
color-diff () {
        color-diff --color $@
}

It's a weird recursive call. Eventually I found out that the cause was my .zshrc being executed twice, if I add echo start to the beginning of the .zshrc and echo end to the end, then run omz reload I will get:

$ omz reload
start
end
start
end

If I add which color-diff to .zshrc, I will get:

$ omz reload
color-diff () {
        diff --color $@
}
color-diff () {
        color-diff --color $@
}

Below is my .zshrc, any help would be appreciated!

We do not define color-diff like that. Please try to reset omz repo following the instructions here and see if it fixes your issue.

Hi @NichtsHsu,

Very interesting!

In your .zshrc, at the top, please add the following:

echo hi mom
return

Double echo?

[NichtsHsu]

Hi @pablos-here ,

It does.

$ omz reload
hi mom
hi mom
ubuntu% 

[pablos-here]

I am sorry, I was not clear. If you start a new konsole terminal from the CLI, double echo?

Also, based on your prompt, your distro is Ubuntu?

I'm wondering if you're affected by the following - https://apple.stackexchange.com/questions/175362/iterm2-runs-my-zshrc-twice

[NichtsHsu]

Hi @pablos-here ,

Thanks again for your help. To my surprise, my .zshenv is a symbolic link to .zshrc, that is why .zshrc was sourced twice. I checked the creation date of the .zshenv file and it almost exactly when I installed this Ubuntu OS two years ago. I have no idea about how and why it was created as a symbolic link to .zshrc, but everything became fine after I remove it.

Hi @NichtsHsu ,

Great news! ;)
