You can use the R programming language.

Here is a quick and dirty R script:

#! /usr/bin/env Rscript d<-scan("stdin", quiet=TRUE) cat(min(d), max(d), median(d), mean(d), sep="\n") 

Note the "stdin" which is a special filename to read from stdin.

Now you can redirect your data over stdin to the R script:

$ cat datafile 1 2 4 $ ./mmmm.r < datafile 1 4 2 2.333333 

Also works for floating points:

$ cat datafile 1.1 2.2 4.4 $ ./mmmm.r < datafile 1.1 4.4 2.2 2.566667 

If you don't want to write an R script file you can invoke a true one-liner in the command line using Rscript:

$ Rscript -e 'd<-scan("stdin", quiet=TRUE)' \ -e 'cat(min(d), max(d), median(d), mean(d), sep="\n")' < datafile 1 4 2 2.333333 

Read the fine R manuals at http://cran.r-project.org/manuals.html.

Unfortunately the full reference is only available in PDF. Another way to read the reference is by typing ?topicname in the prompt of an interactive R session.

For completeness: there is an R command which outputs all the values you want, and more. Unfortunately in a human friendly format which is hard to parse programmatically.

Here is a quick and dirty R script:

#! /usr/bin/env Rscript d<-scan("stdin", quiet=TRUE) cat(min(d), max(d), median(d), mean(d), sep="\n") 

Note the "stdin" in scan which is a special filename to read from standard input (that means from pipes or redirections).

Now you can redirect your data over stdin to the R script:

$ cat datafile 1 2 4 $ ./mmmm.r < datafile 1 4 2 2.333333 

Also works for floating points:

$ cat datafile2 1.1 2.2 4.4 $ ./mmmm.r < datafile2 1.1 4.4 2.2 2.566667 

If you don't want to write an R script file you can invoke a true one-liner (with linebreak only for readability) in the command line using Rscript:

$ Rscript -e 'd<-scan("stdin", quiet=TRUE)' \ -e 'cat(min(d), max(d), median(d), mean(d), sep="\n")' < datafile 1 4 2 2.333333
