Hi,

i need to display the mismatches from two files.The output what is get is the entire rows which mismatch from file 1 are displayed first and the corresponding rows from file 2 are displayed below it.

Sample output:

From Test Run 1 - The row count of file2.txt is 23
From Test Run 1 - The row count of file3.txt is 20
From Test Run 1 - The row count of file4.txt is 2
From Test Run 2 - The row count of file2.txt is 22
From Test Run 2 - The row count of file3.txt is 21
From Test Run 2 - The row count of file4.txt is 1

Code used is:
diff -bi 21.txt 22.txt > 13.txt
sed -e '/^-/d' -e '/^[1-9]/d' -e 's/^[<>] //' 13.txt >> ab.out

how can the ouput be displayed this way?

From Test Run 1 - The row count of file4.txt is 2
From Test Run 2 - The row count of file4.txt is 1
From Test Run 1 - The row count of file2.txt is 23
From Test Run 2 - The row count of file2.txt is 22
From Test Run 1 - The row count of file3.txt is 20
From Test Run 2 - The row count of file3.txt is 21
