George Forman: Free Software (Scripts)
AWK and PERL are great inventions. Here's a handful of scripts I've
found really helpful in my work. Hope they can be of use to others.
"A little script can go a long way."
For numerical data:
-
graphcols **
-
graphs multiple columns of data using gnuplot,
then lets you drive interactively
-
stats
-
computes: min, max, sum, average, standard deviation, coefficient of
variation, and count
-
colstats **
-
ditto, for each column of data
-
median
-
finds the middlemost of a set of numbers
-
medians
-
ditto, for each column of data
-
histogram
-
computes a histogram (discrete or continuous, percentages or total
counts, pdf or cdf); view by piping to 'xgraph' or 'graphcols 1:2'
-
linear.regression
-
computes slope, y-intercept, and correlation coefficient
Others:
-
timeclocks **
-
a Tcl/Tk script to help you track your time spent throughout the day
on various projects/categories, e.g., writing code vs. reading news
vs. errands
-
recol
-
re-formats columns of a table: width of each column determined by max
width item of whole input
-
transpose
-
transpose rows <--> columns
-
dobykey
-
runs your UNIX command on input lines batched by 'key' column
on each line; helps for things like "disk usage by user"
"Reuse, recycle, redistribute freely."
