Golang : List all packages and search for certain package

Problem :

You need to find out if a server has the packages that you need to run or compile your Golang source code. What are the tools available to do that?

Solution :

Use go list command and pipe the output to grep.

For example, to find out if the gorilla mux package is already imported or not.

go list ... | grep mux

Executing go list ... will list all packages and pipe the output to grep to check if mux is listed.

IF not, execute go get github.com/gorilla/mux and repeat go list ... | grep mux again.
