Episodes about using Awk, the text manipulation language. It comes in various forms called awk, nawk, mawk and gawk, but the standard version on Linux is GNU Awk (gawk). It's a programming language optimised for the manipulation of delimited text.
This is the fifteenth episode of the “Learning Awk” series which is being produced by b-yeezi and myself.
This is the second of a pair of episodes looking at redirection in Awk scripts.
In this episode I will spend some time looking at the
getline command used for explicit input (as opposed to the usual implicit sort), often with redirection. The
getline command is a complex subject which I will cover only relatively briefly. You are directed to the
getline section of the GNU Awk User’s Guide for the full details.
I have provided detailed notes as usual for this episode, and these can be viewed here.
