HI,
if a String is present in file1.txt, i want to delete that String from file2.txt.
How can i do this??
I am sure that the file1.txt is a subset of file2.txt.
Do you mean remove lines common to both files?
grep -v -f file1.txt file2.txt > newfile
Otherwise please post example input files and a few lines of expected output.
No, Thanks. This was what i wanted.
