GO mod tidy, go get -u

 go mod tidy is like npm install

installing all libraries in go.mod

its often used with go get -u ./..., 

The command go get -u ./... in Go is used to update all the dependencies of a Go module, including those in all sub-packages. Let’s break it down:

go get -u:

• The -u flag updates the dependencies to their latest compatible versions (minor or patch updates).
• It also updates transitive dependencies.

./... :

• This syntax represents all packages in the current module and all of its sub-packages, recursively.
• It ensures that the command applies to every package in the directory tree starting from the current directory.

This is a go tooling  not linux cmd

 

1. ./:

   • Represents the current directory.
   • A Go convention, not a Linux-specific path.

2. ...:

   • A wildcard that matches all packages and sub-packages recursively within the current module or directory tree.

3. Together: ./...:

   • Specifies "all Go packages in the current directory and its subdirectories."
