Here is a file demonstrating all four:


\starttext

% 1
\immediate\write18{echo -n X >bla1.tex}
X{\endlinechar=-1 \input bla1 }X

% 2
\immediate\write18{echo -n X\letterpercent >bla2.tex}
X\input bla2 X

% 3
\immediate
   \write18
     {echo -n X\letterbackslash\letterbackslash relax >bla3.tex}
X\input bla3 X

% 4
\immediate\write18{echo -n X >bla4.tex}
X{\catcode`\^^M=9 \input bla4 }X

\stoptext
