What Others Think

Wouldn't uniq file1.txt > file2.txt do the same?

Or simply do it like this: uniq file1.txt file2.txt

Useless use of cat

It would be worth to mention, that it doesn't really remove all the duplicate lines. It only removes a line, if it is the same with the next line. To have only uniq lines in file, one can do: sort file1.txt | uniq > file2.txt
