diffutils: Side by Side Format

 
 2.3.1 Controlling Side by Side Format
 -------------------------------------
 
 The '--side-by-side' ('-y') option selects side by side format.  Because
 side by side output lines contain two input lines, the output is wider
 than usual: normally 130 print columns, which can fit onto a traditional
 printer line.  You can set the width of the output with the
 '--width=COLUMNS' ('-W COLUMNS') option.  The output is split into two
 halves of equal width, separated by a small gutter to mark differences;
 the right half is aligned to a tab stop so that tabs line up.  Input
 lines that are too long to fit in half of an output line are truncated
 for output.
 
    The '--left-column' option prints only the left column of two common
 lines.  The '--suppress-common-lines' option suppresses common lines
 entirely.
