Error during: starting shell: fork/exec /usr/bin/zsh: invalid argument Tiling state: Universe[0]() goroutine 1 [running]: runtime/debug.Stack(0x585280, 0xc000128008, 0xc00008dda8) /usr/local/go/src/runtime/debug/stack.go:24 +0x9d main.fatalShutdownNow(0xc000166000, 0x38) /home/z003ejhw/src/github.com/aaronjanse/3mux/main.go:133 +0x17e main.newTerm(0x1, 0x562bd8) /home/z003ejhw/src/github.com/aaronjanse/3mux/pane.go:89 +0x270 main.main() /home/z003ejhw/src/github.com/aaronjanse/3mux/main.go:77 +0x2f9

Would you mind telling me the output of the following commands?

ls -lah /usr/bin/zsh

echo $SHELL

[tinksabraham]

ls -lah /usr/bin/zsh lrwxrwxrwx 1 root root 8 Mar 3 12:10 /usr/bin/zsh -> /bin/zsh

echo $SHELL /usr/bin/zsh

[aaronjanse]

In the meantime, I think 3mux should work if you set $SHELL to zsh.

[tinksabraham]

I don't understand '$SHELL' is already assigned to 'zsh'

[aaronjanse]

'$SHELL' is already assigned to 'zsh'

It's assigned to /usr/bin/zsh. Would you mind running which zsh to see where zsh points to in your $PATH?

[hgoldstein]

I'm running into this as well, but for me 3mux just immediately exits:

$ 3mux -log
$ cat logs.txt
2020/04/22 19:15:57 exec: "zsh": executable file not found in $PATH

EDIT: I see this was fixed though I'm unable to go get -u, I'll open another issue.

[aaronjanse]

EDIT: I see this was fixed

Not sure. Could you provide me the output of which zsh? Also, which OS are you using?

I'm unable to go get -u

Weird. What's the output?

[hgoldstein]

Not sure. Could you provide me the output of which zsh?

I don't have zsh installed so it's just blank:

$ which zsh
$

Also, which OS are you using?

I'm running Ubuntu on WSL ... but yeah, no zsh so this makes sense.

Weird. What's the output?

$ go get -u github.com/aaronjanse/3mux

I don't have zsh installed so it's just blank:

Oh, I wonder why 3mux is trying to launch zsh. Could you tell me the output of $SHELL?

Also, if you run cat /etc/passwd | grep $USER, you should see a shell after the last colon. Could you tell me what it is?

[errors]

Oh, got it. It looks like older versions of golang don't support binary literals. I just pushed a commit to master that replaces the binary literals with normal integers. Would you mind trying go get -u again?

Thank you so much for the bug report and helping me debug!

[hgoldstein]

I wonder why 3mux is trying to launch zsh.

I think what happened is that I had a particularly old version: must have tried to run it, ran into this, forgot about it, then came back to see the bug was still there.

$ echo $SHELL
/usr/bin/fish

Plus /etc/passwd says the same.

Oh, got it. It looks like older versions of golang don't support binary literals

$  go version
go version go1.10.4 linux/amd64

I don't know go all that well so IDK if this is particularly old, but I wouldn't be surprised given I'm on Ubuntu 18.04.

Able to run 3mux now :)

[aaronjanse]

Able to run 3mux now :)

Oh, awesome. 3mux is running fish now, right?

[hgoldstein]

... 3mux is running fish now, right?

That it is!

[aaronjanse]

Awesome!

P.S. I recognize your GitHub account from when I was casually checking out ion a while ago :-)
