Nothing Outputs When Entering Commands

Describe the bug

Installed Warp. Type a command like ls and there's no output. Full screen applications like vim work, but any interactive CLI command shows nothing. Flummoxed.

To reproduce

1. Install Warp
2. Authenticate
3. Type a command like ls

Expected behavior

You should see the output of the command. Like a terminal should. Seems fundamental.

Does this block you from using Warp daily?

Yes, this issue prevents me from using Warp daily.

Is this a Warp specific issue? (i.e. does it happen in Terminal, iTerm, Kitty, etc.)

Yes, this I confirmed this only happens in Warp, not other terminals.

Hi @4rc0s Sorry to hear about this, you may have other versions of fish installed or another shell set as default and Warp is trying to load that. I recommend you run which fish, then put the resulting binary into the Warp Settings > Features > Session > "Startup shell for new sessions" > Custom. Please see more in our docs as well as demo below https://docs.warp.dev/getting-started/using-warp-with-shells#using-fish-shell-with-warp

Hope this helps! Please let us know if the issue persists, or if we're okay to close this issue out.

Thanks for the quick reply. I set fish as you suggested with no luck. (The dropdown was also /usr/local/bin/fish but I also tried setting it manually).

Switching to zsh seems to work, but I lose my customizations etc.

Is it possible that the symlink is messing things up?

ls -l /usr/local/bin/fish
lrwxr-xr-x  1 foo  admin  29 Mar 26  2023 /usr/local/bin/fish -> ../Cellar/fish/3.6.1/bin/fish

I have the same issue - my default shell is fish, and nothing that outputs to stdout emits any output in Warp. Things that render to a curses-like display (bat, broot etc) display their output correctly. Manually setting the shell to fish didn't help either. zsh works as expected.

[dannyneira]

I wonder if it has to do with different versions of fish being installed, run which -a fish, there may be more than one result and the first item on the list is the one that will run when you use fish. In my case, I have the homebrew installed fish first so that is the one I'd set in Settings > Features > Session > "Startup shell for new sessions" > Custom. Hope this helps!

I only have one version of fish installed, the one from homebrew. The thing is, this was working before, it just suddenly stopped. What's puzzling is that Warp and fish are working as expected on another machine, so it's clearly something local.

Same issue here with same config : MacOS 14.1.2, fish installed via Homebrew, only 1 fish version installed, startup shell setting forced to fish path. It used to work 2 months ago and then stopped...

Adding in my voice as well. I have fish installed via brew. /opt/homebrew/bin/fish It is my default. I tried to specify it in features with the custom path but I have the same problem as everyone else. I get the MOTD but nothing entered on the command line works. Warp recognizes bash and zsh and both work when I specify those.
