kubectx errors with Ubound Variable

[Sodman]

Whenever I run kubectx I get the error message in the output: /usr/local/bin/kubectx: line 250: $@: unbound variable.

I assume this is a reference to

kubectx/kubectx

Line 250 in 3504e66

main "$@"

I'm on MacOS (amd64 intel CPU).

kubectx version 0.9.4, installed via brew. Tried reinstalling, no difference.

Happens in both Bash and zsh.

FWIW, kubens also errors - with /usr/local/bin/kubens: line 226: $@: unbound variable

Any idea what might I might be missing in my env?

Edit: I should also add that kubectx some-context actually works fine, it's just the bare kubectx which should list all contexts which is failing for me.

There's a very decent chance your bash version has updated to a newer version that broke something.
I cannot repro this right now. But if you provide a full output with DEBUG=1 env var set, I can take a look.

To unblock yourself, go to Releases tab and download the binary version of kubectx implemented in Go.

Last call to provide s repro with DEBUG=1.

[Sodman]

Thank you for the reminder, apologies for the delay, I had missed the original notification. I will grab latest and try to reproduce again tonight with DEBUG=1.

Output with DEBUG=1:

$ DEBUG=1 kubectx
+ set -eou pipefail
+ IFS='
	'
+ SELF_CMD=/usr/local/bin/kubectx
+ KUBECTX=/Users/sod/.kube/kubectx
/usr/local/bin/kubectx: line 250: $@: unbound variable

Running on zsh 5.7.1 (x86_64-apple-darwin19.0)

I grabbed the binary version from the release and that does indeed work for me, so I'll just pop that in my path. If you'd like me to try anything else, I'm happy to assist - but this workaround fixes all my issues so we can close this out if it's a niche edge case / environment-specific issue not affecting anyone else.

I assume kubectx is running in bash (despite you launch it from zsh) so I may need your bash version as well. 😇

[Sodman]

Apologies for the delay. Bash version info below:
