|twin||can be used to show diffed files side-by-side, so that you can compare them in context. The twin program on the CD-ROM is similar to sdiff, but it allows you to scroll through files alongside one another. twin is also nicer about wrapping lines to make the files easier to read.|
The twin program displays the two files in a split screen, with line numbers in the left margin:
1 | You can use the bc program to |You can also use bc to 3 convert from decimal to hex. |convert from decimal to hex. 4 To do so, use obase to |To do so, use obase to 5 set the base for output: |set the base for output: 6 | 7 obase=16 | obase=16 ...
The highlighted line might be underlined on your terminal. This line is the one that twin notices is different between the files.
twin uses a limited number of commands to move around in
the files, which are shown when you first start up the program. You can use the
u command to move both files
up, and the
v command to move both files down. There
are also commands for moving only one side of the screen - for example,
j to move the right-side text down.
