Question on diff's output

just.srad · 04-03-2008, 07:15 PM

Hi,

Anyone here could help to explain what do the code
"0a1" and "2d2" mean? I tried to search in the web for the explanation but
couldn't find any. Thanks.

Code:

 diff --normal file1 file2
0a1
> hoho
2d2
< hee
4,7c4
<  
<  
<  
<  
---
> yo

To make file2 from file1,

at line 0 of file1, insert a line, which becomes line 1 in file2

at line 2 of file1, delete the line, but a line 2 still exists in file2 (not entirely sure of this one)

from lines 4 through 7 of file1, change by removing 4 lines from file1, and replacing them with 1 line, which becomes line 4 of file2

Thanks man, that's a great one. It's more of a information , i think i can ignore it , just take note of the ">" and "<" signs will do.
