%%% Taco Hoekwater: 4 endless lines % The end of a line in an \input-ed file normally creates a space in the output, % TeX appends a character with the current value of \endlinechar to each that % character is later converted to a space. \immediate\write18 {echo -n Y >bla.tex} X\input bla Z % gives XY Z % If you do not want that space, for instance because you want to typeset the % of the file in-line, then there are a number of options. Two are usable % writing, and two others during type reading. % 1. Writing a percent sign to the end of the line works \immediate\write18 {echo -n Y\letterpercent >bla.tex} X\input bla Z % gives XYZ % 2. Another option is ending the written line with \relax or a similar % space-gobbling command. \immediate\write18 {echo -n Y\letterbackslash\letterbackslash relax >bla.tex} X\input bla Z % gives XY\relax Z % 3. Temporarily setting \endlinechar to an impossible value like -1 is a possibility \immediate\write18 {echo -n Y >bla.tex} X{\endlinechar=-1 \input bla }Z % gives XYZ % 4. Changing the catcode of the current \endlinechar to 9 (ignored) also works \immediate\write18 {echo -n Y >bla.tex} X{\catcode'\^^M=9 \input bla }Z % gives XYZ \end
