AWK is a scripting language that was originally designed for manipulating tables and presenting them in human-readable formats. It is useful on the commandline, I'd prefer to use a more powerful language than awk than use it for scripting.


WARNING:

There are two main variations of the unix coreutils (Gnu/BSD), each has different parameters etc. If you are expecting to use awk across different platforms, make no assumptions.

Syntax

system

Executes a command in shell or cmd from an awk script. Assigning to a variable only gives return value (1,0)

system(ls -la);

math

var+= 1;
var=( (100/2) * 3 );
