unix diff side-to-side results

Question

How can I plot the results of a unix diff command side-to-side instead of one difference after the other  See below for an example           diff  tmp test1   tmp test2 1 4c1 2  lt  asfdsadf  lt  asdfsad  lt  fsaf  lt  fdsadf ---  gt  asdfsafdsf  gt  saf 6 8d3  lt  sadf  lt  asdf  lt  sadf 10d4  lt  fasd 12 13c6 14  lt  sadfa  lt  fd ---  gt  sadf  gt  sadf  gt  sadf  gt  sadf  gt  sadf  gt  sadf  gt  sadf  gt  sadf  gt  safa   I would like to have something like   diff  tmp test1   tmp test2 1 4c1 2  lt  asfdsadf        gt  asdfsafdsf  lt  asdfsad         gt  saf         lt  fsaf  lt  fdsadf --- 6 8d3  lt  sadf  lt  asdf  lt  sadf 10d4  lt  fasd 12 13c6 14  lt  sadfa                gt  sadf  lt  fd               gt  sadf ---                gt  sadf                gt  sadf                gt  sadf                gt  sadf                gt  sadf                gt  sadf                gt  safa

Use the -y option   diff -y file1 file2

User · Answer

From man diff  you can use -y to do side-by-side   -y  --side-by-side        output in two columns   Hence  say   diff -y  tmp test1   tmp test2   Test    cat a                  cat b hello                  hello my name                my name is me                  is you   Let s compare them     diff -y a b hello                                                           hello my name                                                         my name is me                                                           is you

You should have sdiff for side-by-side merge of file differences  Take a read of man sdiff for the full story

User · Answer

You can simply use   diff -y fileA txt fileB txt   colordiff   It shows the output splitted in two colums and colorized   colordiff

You can use   sdiff  file1 file2   or   diff -y file1 file2   or  vimdiff file1 file2   for side by side display

From icdiff s homepage    Your terminal can display color  but most diff tools don t make good use of it  By highlighting changes  icdiff can show you the differences between similar files without getting in the way  This is especially helpful for identifying and understanding small changes within existing lines  Instead of trying to be a diff replacement for all circumstances  the goal of icdiff is to be a tool you can reach for to get a better picture of what changed when it s not immediately obvious from diff   IMHO  its output is much more readable than diff -y

Try cdiff - View colored  incremental diff in workspace or from stdin with side by side and auto pager support

Enhanced diff command with color  side by side and alias  Let s say the file contents are like   cat  tmp test1 txt 1 2 3 4 5 8 9   and  cat  tmp test2 txt 1 1 5 2 4 5 6 7   Now comparing side-by-side  diff --width  COLUMNS --suppress-common-lines --side-by-side --color always  tmp test1 txt  tmp test2 txt                                                                                gt  1 5 3                                                                              lt  8                                                                               6 9                                                                               7   You can define alias to use  alias diff  diff --width  COLUMNS --suppress-common-lines --side-by-side --color always    Then new diff result   diff  tmp test1 txt  tmp test2 txt                                                                                gt  1 5 3                                                                              lt  8                                                                               6 9                                                                               7
