Re[4]: How to write an execline helper in execline?

[Laurent Bercot]

Hi, slightly among the lines of this suggestion, is there anything to help templating files with a given set (or subset) of env vars? This would be nice addition for s6 overlay

 I can't think of anything simpler than

s6-envdir dir_containing_all_variable_definitions
multisubstitute
{
  import -u variable1
  import -u variable2
  import -u variable3
  ...
}
script_using_variables

 Is that the kind of thing you're looking for?
