Why is 'kubectl' is not recognized as an internal or external command on WIndows?

Question

I edited env variables by pointing to kubectl and helm(after downloading them and storing into kube folder)

when I go for kubectl in cmd,I got 'kubectl' is not recognized as an internal or external command,

operable program or batch file.

Why?

Answer 1

Environment variables are not automatically used this way. The only variable that Cmd uses to find the location of commands is PATH, which is a list of directories (not files) that Cmd will look in.

Since PATH is already there in your environment variable window, just edit it to include the path to your C:\users\f85147\kube directory.

(On Windows, 'Path' and 'PATH' are the same thing.)

Other variables such as 'helm' aren't used to find commands. They're only used through explicit expansion when you type %helm% in Cmd, or $helm in Bash, or $env:helm in PowerShell (but never bare helm) and this expands to whatever value you've set in the variable.
