batch file - how to escape every character up to a point? -

situation :

i want variable contain command can execute doing :

%command% 

tries :

set command=echo file used cleaning executable ^>^> dummyfile %command% 

this works, have specific editing each command... isn't there take after = symbol quote?

set command="echo file used cleaning executable >> dummyfile" %command% 

then command not recognised because of quotes

your idea quoting not bad:

set "command=echo file used cleaning executable >> dummyfile"
