You can change the format of the expressions either for the whole file
(see example below) or on an expression basis by enclosing the
expression with a wrapper function such as, say, TexForm, etc. Section
2.12.3, "Advanced Topic: Streams and Lowâ??Level Input and Output," of
/The Mathematica Book/ explains all of these points in details .
stream1 = OpenRead["c:\\temp\\inputFile.txt"];
stream2 = OpenWrite["c:\\temp\\outputFile.txt",
FormatType -> OutputForm];
dummy = Read[stream1, "String"];
While[dummy =!= EndOfFile,
If[dummy != "a", Write[stream2, dummy]];
dummy = Read[stream1, "String"]; ]
