- _s_d_i_f_f uses the output of _d_i_f_f(1) to produce a side-by-side listing of two
- files indicating those lines that are different. Each line of the two
- files is printed with a blank gutter between them if the lines are
- identical, a <<<< in the gutter if the line only exists in _f_i_l_e_1, a >>>> in the
- gutter if the line only exists in _f_i_l_e_2, and a |||| for lines that are
- different.
-
- For example:
-
- x | y
- a a
- b <
- c <
- d d
- > c
-
- The following options exist:
-
- ----wwww _n Use the next argument, _n, as the width of the output line.
- The default line length is 130 characters.
-
- ----llll Only print the left side of any lines that are identical.
-
- ----ssss Do not print identical lines.
-
- ----oooo _o_u_t_p_u_t Use the next argument, _o_u_t_p_u_t, as the name of a third file
- that is created as a user-controlled merging of _f_i_l_e_1 and
- _f_i_l_e_2. Identical lines of _f_i_l_e_1 and _f_i_l_e_2 are copied to
- _o_u_t_p_u_t. Sets of differences, as produced by _d_i_f_f(1), are
- printed; where a set of differences share a common gutter
- character. After printing each set of differences, _s_d_i_f_f
- prompts the user with a %%%% and waits for one of the following
- user-typed commands:
-
- llll append the left column to the output file
-
- rrrr append the right column to the output file
-
- ssss turn on silent mode; do not print identical lines
-
- vvvv turn off silent mode
-
- eeee llll call the editor with the left column

-
- eeee rrrr call the editor with the right column
-
- eeee bbbb call the editor with the concatenation of left
- and right
-
- eeee call the editor with a zero length file
-
- qqqq exit from the program
-
- On exit from the editor, the resulting file is concatenated on
- the end of the _o_u_t_p_u_t file.
