$ cat data.txt aaaaaa aaaaaa cccccc aaaaaa aaaaaa bbbbbb $ cat data.txt | uniq aaaaaa cccccc aaaaaa bbbbbb $ cat data.txt | sort | uniq aaaaaa bbbbbb cccccc $
The result that I need is to display all the lines from the original file removing all the duplicates (not just the consecutive ones), while maintaining the original order of statements in the file.
Here, in this example, the result that I actually was looking for was
aaaaaa cccccc bbbbbb
How can I perform this generalized
uniq operation in general?
