I have 2 files that I want to differ. File B is produced appending some new line to file A.
I want to highlight the appended data by using diff
.
I would like to avoid printing out the '>' characters and the '10a11,14' of the output below.
Reading the man pages of diff
I can see that you can specify the formatting of the result ( LFMT ) but I am struggling in producing something useful.
Could you help in removing those characters I don't need?
Regards
AFG
diff --left-column A.txt B.txt
10a11,14
> TXT : some text
> some text
> some text
> some text

There are two easy ways of doing this, you can either parse the output of
diff
or you can usecomm
.diff fileA fileB | grep '>' | sed 's/> *//'
comm -13 fileA fileB
