Problem with uniq command
Say I have a file name "reading.txt" with lots of duplicates:
book
book
paper
paper
article
article
magazine
magazine
I want to remove the duplicates, so I typed this
"uniq reading.txt"
The output should come like this
book
paper
article
magazine
But it shows all elements of reading.txt file like this
[z@localhost Documents]$ cat reading.txt book
book
paper
paper
article
article
magazine
magazine [z@localhost Documents]$ uniq reading.txt book
book
paper
paper
article
article
magazine
magazine [z@localhost Documents]$
