I think you probably want:


task :default => checkfile

checkfile = "arrangement0/list.txt"
file checkfile do
        regenarate
end


AFAIK tasks are more like functions, dependent on other tasks, which must be
done first. 'file' creates a file task, which will run in order to create
that target (checkfile).
If you want checkfile to be dependant on other files:

file checkfile => [depfile1, depfile2] do
        regenarate
end

For more info, go through the tutorial:
http://onestepback.org/articles/buildingwithrake/filetasks.html

PS: regenerate, not regenarate
