fmt − fmt
[OPTION]... [FILE]...
Reformat paragraphs from input (or standard input) to stdout.
[FILES]...
−c, −−crown−margin
First and second line of paragraph may have different indentations, in which case the first line’s indentation is preserved, and each subsequent line’s indentation matches the second line.
−t, −−tagged−paragraph
Like −c, except that the first and second line of a paragraph *must* have different indentation or they are treated as separate paragraphs.
−m, −−preserve−headers
Attempt to detect and preserve mail headers in the input. Be careful when combining this flag with −p.
−s, −−split−only
Split lines only, do not reflow.
−u, −−uniform−spacing
Insert exactly one space between words, and two between sentences. Sentence breaks in the input are detected as [?!.] followed by two spaces or a newline; other punctuation is not interpreted as a sentence break.
−p, −−prefix <PREFIX>
Reformat only lines beginning with PREFIX, reattaching PREFIX to reformatted lines. Unless −x is specified, leading whitespace will be ignored when matching PREFIX.
−P, −−skip−prefix <PSKIP>
Do not reformat lines beginning with PSKIP. Unless −X is specified, leading whitespace will be ignored when matching PSKIP
−x, −−exact−prefix
PREFIX must match at the beginning of the line with no preceding whitespace.
−X, −−exact−skip−prefix
PSKIP must match at the beginning of the line with no preceding whitespace.
−w, −−width <WIDTH>
Fill output lines up to a maximum of WIDTH columns, default 75. This can be specified as a negative number in the first argument.
−g, −−goal <GOAL>
Goal width, default of 93% of WIDTH. Must be less than or equal to WIDTH.
−q, −−quick
Break lines more quickly at the expense of a potentially more ragged appearance.
−T, −−tab−width <TABWIDTH>
Treat tabs as TABWIDTH spaces for determining line length, default 8. Note that this is used only for calculating line lengths; tabs are preserved in the output.
−h, −−help
Print help
−V, −−version
Print version
