LinuxQuestions.org - Qdiff updated!

Here is the full help text:
Code:
Usage: qdiff [OPTION]... FILE1 FILE2





diff options:

-b --byte-by-byte        compare files byte by byte, like 'cmp'

-f --no-heuristics      do not use heuristics to speed up large differing

                        blocks, note that the result is always correct but

                        with this option you may find a smaller number of

                        differing bytes

-m --min-match=NUM      allow resynchronisation only after a minimum of NUM

                        bytes match, this is an important parameter: lower

                        values may result in a more detailed analysis or in

                        useless results, higher values give a coarse analysis

                        but resynchronisation is more robust (range=[1..],

                        default=20)

-O --large-files        optimize disk access for large files on the same disk

                        (locks 16MB mem)



output modes:  (override automatic file type determination)

-a --formatted          print formatted ascii text, line by line

-u --unformatted        print unformatted ascii text, block by block

-x --hex                print hex dump, block by block

-t --vertical            print one byte per line (ignores width)



output options:

-c --no-color            disable ansi coloring of output

-C --alt-colors          no bold ansi coloring (for SGI terminals and the like)

-w --width=NUM          output maximal NUM chars (default is terminal width)

-B --bytes-per-line=NUM  print NUM bytes/chars per line

-T --tab-size=TABSIZE    TABSIZE in formatted mode (range=[1..], default=8)

-l --line-numbers        print line numbers in formatted mode

-n --no-line-break      truncate (not break) lines in formatted mode

-L --show-lf-and-tab    show newline/tab as <LF>/<HT> in formatted mode

-S --show-space          show space as <SPC> in non hex modes

-U --unprintable=CHAR    print CHAR for unprintable chars in non hex modes

-H --control-hex        print control codes in hex (<x1B>, not <ESC>)

-A --alignment-marks    print -/+ before 32/64-bit words in hex mode

-e --stop-on-eof        stop when end of a file is reached in vertical mode

  --hide-match          do not print matches

  --hide-deletion      do not print deletions

  --hide-insertion      do not print insertions

  --hide-substitution  do not print substitutions

  --range-match        print match as byte range

  --range-deletion      print deletion as byte range

  --range-insertion    print insertion as byte range

  --range-substitution  print substitution as two byte ranges

-R --range              print everything as byte range



common options:

-v --verbose            verbose execution

-P --progress            show progress during work

-h --help                print this help message, then exit successfully

  --version            print version, then exit successfully
