All of these scripts read from standard input and write to
standard out. Most of them convert from some file or format
type to another one and use the colon character ":" as
a field delimiter (although this is specified separately for
the most part).
This script will convert from a array
type file into a html table. It is pretty handy for putting
your results up on the web, and I actually prefer using this script
instead of coding in the bulky HTML table notation. Here is an
example of the output generated
from using it.
- array2tab.awk: A
really simple script to replace the colons with tabs.
- array2tex.awk: This
script will convert from a array type
file into a TeX table for inclusion in papers. I hate making
TeX tables with a passion, so now I always use this script to do it
for me. Here is an example of the TeX
output and what it looks like after rendering it with LaTeX
into postscript and then into a picture.
- arrayify.awk: Perhaps
the most useful script in the bunch, this takes a list of data (as can be easily created
by greping though all of your data files) and puts it into a big array (from which you can easily make
tables and graphs. It's pretty simple, but a very versatile
- corrcoef.awk: This
script will calculate the coeficient of correlation for list of x,y
pairs. I am not possitive that it is correct, so if you want to
use it for something important make sure that you verify the
A handy awk script to convert a list of decimal numbers into
This is another simple Tex authoring utility. It takes a set
of lines and paragraphs and makes lists out of it.
The array type files are
really handy for using awk, sed, or perl on, but they are not that
easy to read by humans. The prettyarray script will take an array type file and make a
human readable text only table
by evenning out the white space and
adding some ASCII lines between rows and collumns. One feature is that
the first collumn is used to determine weather or not to insert a
horizontal spacer or not, so it is also handy for looking and lists
of numbers too (For example if you put

Transpose a text array. The

This is the inverse of arrayify.awk.
It takes a text array and converts
it back into list of data, which can
sometimes be handy.
