The spacing at the beginning 55 of the input lines is preserved in the output, as are blank lines 56 and interword spacing. 57 .PP 58 .I Fmt 59 is meant to format mail messages prior to sending, but may also be useful 60 for other simple tasks. 61 For instance, 62 within visual mode of the 63 .I ex 64 editor (e.g. 65 .IR vi ) 66 the command 67 .sp 68 !}fmt 69 .sp 70 will reformat a paragraph, 71 evening the lines. 72 .PP 73 The following options can be used 74 to alter the behavior of 75 .IR fmt : 76 .TP 77 .B \-c 78 Select crown margin mode 79 (for tagged paragraphs). 80 Paragraphs are separated by empty lines. 81 The indenting of the first and second line 82 of each paragraph is preserved, 83 and following lines are indented 84 like the second line. 85 .TP 86 .B \-s 87 Split lines, 88 but do not join lines 89 (i.\|e. preserve any newline character 90 found in the input file). 91 .TP 92 \fB\-w\fI\ width\fR 93 Set the length of generated output lines to 94 .I width 95 characters. 96 .SH "ENVIRONMENT VARIABLES" 97 .TP 98 .BR LANG ", " LC_ALL 99 See 100 .IR locale (7). 101 .TP 102 .B LC_CTYPE 103 Determines the mapping of bytes to characters, 104 the width of characters, 105 and the set of word-separating characters. 106 .SH "SEE ALSO" 107 nroff(1), 108 mailx(1), 109 vi(1) 110 .SH NOTES 111 The program was designed to be simple and fast \- for more complex 112 operations, the standard text processors are likely to be more appropriate. 113 .PP 114 The original version of this program was written by 115 Kurt Shoens.
