Concatenate files on the command line, or read text from standard input if - (or no file) is specified. By default, preserve blank lines, spacing, and indentation. fmt attempts to break lines at the end of sentences and to avoid breaking lines after a sentence’s first word or before its last. Options -c, –crown-margin Crown margin mode. Do not change each paragraph’s first two lines’ indentation. Use the second line’s indentation as the default for subsequent lines. -p prefix, –prefix=prefix Format only lines beginning with prefix. -s, –split-only Suppress line-joining. -t, –tagged-paragraph Tagged paragraph mode. Same as crown mode when the indentation of the first and second lines differs. If the indentation is the same, treat the first line as its own separate paragraph. -u, –uniform-spacing Print exactly one space between words and two between sentences. -w width, –width=width Set output width to width. The default is 75. –help Sponsored by:

XML -Ca Align tables for memory access and computation. This creates larger tables but gives faster performance. -Ce Construct equivalence classes. This creates smaller tables and sacrifices little performance (default). -Cf Generate full scanner tables, not compressed. -CF Generate faster scanner tables, like -F. -Cm Construct metaequivalence classes (default). -Cr Bypass use of the standard I/O library. Instead use read() system calls. Return to: Alphabetical Directory of Linux Commands Copyright 2000-2002 O’Reilly & Associates, Inc. All Rights Reserved.
