There's also stdev by Tom Christiansen: * http://stackoverflow.com/questions/9789806/command-line-utility-to-print-statistics-of-numbers-in-linux * https://bitbucket.org/shlomif/shlomif-computer-settings/src/04cdfe5b0eee641885bd30fd5c891dd6dfb7f1d8/shlomif-settings/home-bin-executables/bin/stdev?at=default > Command line users of linux on many distributions have been restricted to > sc or variants and teapot for spreadsheets and those can't do this kind of > work. psql and mysql can't do standard deviations either. psql can: http://www.postgresql.org/docs/current/static/functions-aggregate.html See "stddev_samp" and "stddev_pop" . > php may be a > solution, but that involves learning another language. PHP for command-line work? That sounds wrong (not that PHP is a good language even for writing server-side web code). Perhaps use Perl, Python, Ruby, Lua, Awk, etc. or Something like R. I should note that I'm maintaining this Perl 5/CPAN module for some basic statistical calculations: https://metacpan.org/release/Statistics-Descriptive There are plenty of others like that for Perl and similar languages and learning a language like that is useful for many other use-cases.
