11.2) Compare Files

First, make a copy of ‘file1’ and call it ‘file4’. Now use emacs to change the ‘4.3’ in the second column/second row to a 5.3.

Now you can use diff to highlight the difference that you just made. Type:

diff file1 file4

The result will look like:

2c2
< 0.2   4.3
---
> 0.2   5.3

See the next page for a description of the results.
