Hi!! I just need a version of Uniq command for unix, written in C programming language that does basically all the same thing as uniq command does + it should be able to read from standard input. It should work with my ubuntu

uniq is a Unix utility which, when fed a text file, outputs the file with adjacent identical lines collapsed to one. If a filename is provided on the command line (i.e, uniq FILE) then uniq should open it, read, filter out, print without repeated lines in this file, and then close it. If no filename is provided, uniq should read from standard input. You should also be able to invoke it without a file, and have it read from standard input. For example, you can use a pipe to direct the output of another xv6 command into uniq: Hints Many aspects of this are similar to the we program: both can read from standard input if no arguments are passed or read from a file if one is given on the command line. Reading its code will help you if you get stuck. 1. 2. Still confused with uniq's behavior? Use man uniq for help. uniq is a Unix utility which, when fed a text file, outputs the file with adjacent identical lines collapsed to one.
