ikiwiki --wrapper can be used to generate a wrapper program that runs ikiwiki with the specified parameters. This is used for [[post-commit]] hooks, [[CGI]], etc, both for convenience and because these things often need suid wrapper scripts to make ikiwiki run as the right user. The generated wrapper is a binary program. What if you want to regenerate it with different parameters, or just run ikiwiki like it would but with some parameter changed? To easily accomomplish this, the wrappers all support being run with --params, which causes them to print out the parameters they run ikiwiki with. You can use this trick to regenerate a wrapper, adding or changing a parameter: ikiwiki $(./ikiwiki-wrap --params) --wikiname="newname" --wrapper Or just to run ikiwiki like the wrapper would, and add a parameter: ikiwiki $(./ikiwiki-wrap --params) --rebuild
