How to run command-line command on non-contiguous lines, specifying individual line numbers?

Question

For example, say I want to replace foo with bar on lines 1,3,11, and 15. How could I do that?

:1,15s/foo/bar

will replace foo with bar on lines 1-15. But I want to specify multiple individual lines (1,3,11,15), not a range (1-15).

How do you come up with the line numbers? If this is a manual process of visual inspection, you could make use of the multiselect plugin. It allows you to select multiple, non-contiguous ranges, and then you can apply a command on them:

:MSExecCmd s/foo/bar
