extracting unique lines from text file
I have a file with 14million lines and I would like to extract all the unique lines from the file into another text file.
For example: Contents of file1 happy sad smile happy funny sad I want to run a command against file one that only returns the unique lines (ie 1 line for happy and 1 line for sad). Could someone please point me in the right direction. Thanks |
