Icdiff

Improved colored diff

Installation

Put icdiff on your PATH.

##Usage

icdiff [options] left_file right_file

Show differences between files in a two column view.

Options

 --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
--head=HEAD consider only the first N lines of each file
--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
--line-numbers generate output with line numbers
--no-bold use non-bold colors; recommended for with 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
--recursive recursively compare subdirectories
--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
-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
--whole-file show the whole file instead of just changed lines and
context
