Hello Datamash
I have this datamash at work, (using alias dm=datamash)
$ dm --version
datamash (GNU datamash) 1.3

and exploring the mode and anitmode operations:
$ dm unique 5 < data.txt
12.0,24.0,8.0,999.0
$ cat data.txt | grep '24.0' | wc -l
5917
$ cat data.txt | grep '8.0' | wc -l
935
$ cat data.txt | grep '999.0' | wc -l
1
$ dm mode 5 < data.txt
24
$ dm antimode 5 < data.txt
8
I would have expected anitmode to output 999 here but that might be
because of my poor understanding of the operation. Am I
missunderstanding the meaning of "least common value"? I can happily
share the data file if necessary.
Best regards
