Sorry for the nitpicking. But this sometimes might not work. For example
$cat temp1.txt
temp3
temp1
$cat temp2.txt
temp2
temp3
temp4
temp1
temp5
$comm -3 temp1.txt temp2.txt
temp2
temp1
temp4
temp1
temp5
$diff temp1.txt temp2.txt | grep '^>' | cut -f 1 -d ' ' --complement
temp2
temp4
temp5
The OP did not mention that his files were sorted. So comm command might not
be applicable for his case.
