icdiff [options] left_file right_file

  --version             show program's version number and exit
  -h, --help            show this help message and exit
  --cols=COLS           specify the width of the screen. Autodetection is Unix
                        only
  --encoding=ENCODING   specify the file encoding; defaults to utf8
  -E MATCHER, --exclude-lines=MATCHER
                        Do not diff lines that match this regex. Not
                        compatible with the 'line-numbers' option
  --head=HEAD           consider only the first N lines of each file
  -H, --highlight       color by changing the background color instead of the
                        foreground color.  Very fast, ugly, displays all
                        changes
  -L LABELS, --label=LABELS
                        override file labels with arbitrary tags. Use twice,
                        one for each file
  -N, --line-numbers    generate output with line numbers. Not compatible with
                        the 'exclude-lines' option.
  --no-bold             use non-bold colors; recommended for solarized
  --no-headers          don't label the left and right sides with their file
                        names
  --output-encoding=OUTPUT_ENCODING
                        specify the output encoding; defaults to utf8
  -r, --recursive       recursively compare subdirectories
  -s, --report-identical-files
                        report when two files are the same
  --show-all-spaces     color all non-matching whitespace including that which
                        is not needed for drawing the eye to changes.  Slow,
                        ugly, displays all changes
  --tabsize=TABSIZE     tab stop spacing
  -t, --truncate        truncate long lines instead of wrapping them
  -u, --patch           generate patch. This is always true, and only exists
                        for compatibility
  -U NUM, --unified=NUM, --numlines=NUM
                        how many lines of context to print; can't be combined
                        with --whole-file
  -W, --whole-file      show the whole file instead of just changed lines and
                        context
  --strip-trailing-cr   strip any trailing carriage return at the end of an
                        input line
  --color-map=COLOR_MAP
                        choose which colors are used for which items. Default
                        is --color-map='add:green_bold,change:yellow_bold,desc
                        ription:blue,meta:magenta,separator:blue,subtract:red_
                        bold'.  You don't have to override all of them:
                        '--color-map=separator:white,description:cyan
