Command Line Examples: gawk
From PHYSpedia
gawk is a powerful stream editor that can be used in command pipelines to perform special functions that do not have a command written for. The easiest use of gawk (and a very common one) is to manipulate the columns in text stream.
In the examples that follow, assume that a file name test-data.txt exists and contains 3 columns of data.
eigen % cat test-data.txt 1 11 21 2 12 22 3 13 23 4 14 24
