Multiple occurences of a number...

[iceman4000000]

Hi everyone... imagine a file which contains a column. In this one column, there are hundreds of rows containing a number - so it looks like a column extracted from an excel spreadsheet. Some of the numbers appear several times. I have sorted the column into numerical order. Does anyone know how I can get rid of the multiple occurences of numbers, so that every number in the file is unique? I'd much appreciate it...

If I understand correctly, sort -u filename should work.

If the file is already sorted, you could also use uniq infile outfile.

Use

uniq file > newfile

Hope this helps. CaKiwi
