Data and documentation
Common questions and answers.
Entire collection of data resources.
Purpose: To allow a user to pull off selected columns of data. This should be used to view the contents of selected columns rather than used as an extraction tool, as the program does not allow one to simultaneously pull off columns 6-7, 11-13, 49-50, and 51-57.
One can get the same results with awk and/or cut in UNIX. However, these UNIX utilities will only work with data that have short record lengths.
To run, enter column x y < z
column 12 13 < data | more
column 50 54 < data > doc
head -20 data | column 79 80 > doc
tail -15 data | column 79 80 >> doc
