Wow, that's cool. I never saw uniq before. I just read the man and tried it out. Wouldn't he just want uniq infile outfile since -u option will remove all instances of a repeated element, where as uniq f1 f2 will leave one instance of said repeating element? I did for 1 in 1 2 3 4 5 6 7 8 9; do echo banana >> banana; done then echo "orange you glad I didn't say banana?
