Thanks for the suggestion. Note that the code has this: /* Size of paragraph buffer, in words and characters. Longer paragraphs are handled neatly (cf. flush_paragraph()), so long as these values are considerably greater than required by the width. These values cannot be extended indefinitely: doing so would run into size limits and/or cause more overflows in cost calculations. FIXME: Remove these arbitrary limits. */ #define MAXWORDS 1000 #define MAXCHARS 5000 where MAXCHARS/2 specifies the largest width. I.e., fmt -w 2500 works, but not 2501. We agree that there should not be such a limit. But the internals of fmt are not pretty -- significantly less so than most other parts of the coreutils, and as the comment says we cannot easily increase them arbitrarily. In the mean time what can you do if you want truly unlimited-length paragraphs? It's not trivial since you want to retain paragraph delimiters. This perl command should do the trick. It processes your input a paragraph at a time, replacing each newline (and spaces before/after) with a single space: perl -00ple 's/\s*\n\s*/ /g' E.g., given this input, 1 2 3 4 1 2 3 4 5 It prints this: $ (seq 4; echo; seq 5) | perl -00ple 's/\s*\n\s*/ /g' 1 2 3 4 1 2 3 4 5 It doesn't preserve indentation, but if you're just going to paste it into libreoffice, that should be fine. I've Cc'd the upstream bug-tracker, so we'll have a bug number there, too.
