How do I list packages whose binaries are installed in $GOBIN?

Question

If I understand correctly, go install puts binaries in $GOBIN directory.

I tend to forget which packages provide which binaries in $GOBIN and which packages I go install-ed.

Is there a way to list packages that are currently go install-ed?

I could, obviously, do ls $GOBIN and that'll give me names of binaries. However, I'm looking for a way to get a list of packages with their long names, e.g. github.com/operator-framework/operator-sdk.

Update: go list ... (suggested here) does not seem to apply to my case because this command expects me to be in a directory containing go.mod file. I understand that go list is designated for listing packages of a project. In my case, I need to find out all packages that are installed into $GOBIN of my system/user.

Have you tried it? What's the output when you run go list all in a folder outside GOPATH and without a go.mod? (and what's your go version). – Kmeson

@Kmeson go list all -> go: warning: "all" matched no packages, go version -> go version go1.16.2 linux/amd64 – Simmer

For each binary in $GOBIN, you can use go version -m to show information about the version of Go and the module versions that were used to build that binary. For example, here's go version -m ~/go/bin/goimports for me.

$ go version -m ~/go/bin/goimports
/Users/jayconrod/go/bin/goimports: go1.15.2
    path    golang.org/x/tools/cmd/goimports
    mod golang.org/x/tools  v0.0.0-20200910165216-53e29e9d1252  h1:qn28WK3EvdJOSlyZFNeWnaEX8X5GiQv+8mrw9mYrXko=
    dep golang.org/x/mod    v0.3.0  h1:RM4zey1++hCTbCVQfnWeKs9/IEsaBLA8vTkd0WVtmH4=
    dep golang.org/x/xerrors    v0.0.0-20200804184101-5ec99f83aff1  h1:go1bK/D/BFZV2I8cIQd1NKEZ+0owSTG1fDTci4IqFcE=

The path line shows the name of the main package that was installed. Looks like I need to update it.

$ go install golang.org/x/tools/cmd/goimports@latest
$ go version -m ~/go/bin/goimports
/Users/jayconrod/go/bin/goimports: go1.17rc1
    path    golang.org/x/tools/cmd/goimports
    mod golang.org/x/tools  v0.1.5  h1:ouewzE6p+/VEB31YYnTbEJdi8pFqKp4P4n85vwo3DHA=
