title: How do I list packages whose binaries are installed in $GOBIN?
body: <p>If I understand correctly, <code>go install</code> puts binaries in <code>$GOBIN</code> directory.</p>
  <p>I tend to forget which packages provide which binaries in <code>$GOBIN</code> and which packages I <code>go install</code>-ed.</p>
  <p>Is there a way to list packages that are currently <code>go install</code>-ed?</p>
  <p>I could, obviously, do <code>ls $GOBIN</code> and that'll give me names of binaries. However, I'm looking for a way to get a list of packages with their long names, e.g. <code>github.com/operator-framework/operator-sdk</code>.</p>
  <p><strong>Update:</strong> <code>go list ...</code> (suggested <a href="https://stackoverflow.com/a/30401805/484050">here</a>) does not seem to apply to my case because this command expects me to be in a directory containing <code>go.mod</code> file. I understand that <code>go list</code> is designated for listing packages of a <em>project</em>. In my case, I need to find out all packages that are installed into <code>$GOBIN</code> of my <em>system</em>/user.</p>
