command line utility to print statistics of numbers in linux

Question

I often find myself with a file that has one number per line. I end up importing it in excel to view things like median, standard deviation and so forth.

Is there a

Answer 1

Also, the self-write stats, (bundled with 'scut') a perl util to do just that. Fed a stream of numbers on STDIN, it tries to reject non-numbers and emits the following:

$ ls -lR | scut -f=4 | stats
Sum       3.10271e+07
Number    452
Mean      68643.9
Median    4469.5
Mode      4096
NModes    6
Min       2
Max       1.01171e+07
Range     1.01171e+07
Variance  3.03828e+11
Std_Dev   551206
SEM       25926.6
95% Conf  17827.9 to 119460
          (for a normal distribution - see skew)
Skew      15.4631
          (skew = 0 for a symmetric dist)
Std_Skew  134.212
Kurtosis  258.477
          (K=3 for a normal dist)

It can also do a number of transforms on the input stream and emit only the unadorned value if you ask it; ie 'stats --mean' will return the mean as an unlabelled float.
