Random Notes on Comparing Files (Linux)

diff <(sort File1.csv) <(sort File2.csv) | grep '^>' | cut -c3-
comm -13 <(sort file1.txt) <(sort file2.txt)
comm -23 <(sort file1.csv) <(sort file2.csv) > file3.csv
grep -v -f file2.csv file1.csv > file3.csv
For whole lines that are present in file1.csv but not in file2.csv you probably want
grep -xvFf file2.csv file1.csv
