_kube_ps1_file_newer_than:16: division by zero #159

Closed nareshku closed 2 years ago

nareshku commented 2 years ago

Using kube-ps1 on my Linux machine with zsh and found that zstat doesn't output nanoseconds leading to error _kube_ps1_file_newer_than:16: division by zero

zstat +mtime -F %s.%N ~/kube/config
1658797744.%N

Full output of zstat

We should probably get the OS type and convert command zstat +mtime -F %s.%N to zstat +mtime -F %s if it is Linux here

Interesting. Which version of zsh are you using? I am running Linux and tested on different distributions without that issue: 

$ zsh --version
zsh 5.8 (x86_64-ubuntu-linux-gnu)                                             
testuser at dev-box in ~ 

$ zstat +mtime -F %s.%N ~/.kube/config          
1658946238.553962684

Wow, ok. This version was released almost 10 years ago: 2012-12-21. I assume you are on an older version of RHEL? The nanosecond precision was introduced around version 5.5. I will add a condition for older versions of ZSH but would definitely suggest upgrading your shell at some point.

I also got this issue:

_kube_ps1_file_newer_than:15: division by zero
zsh --version
zsh 5.0.2 (x86_64-redhat-linux-gnu)
