Here is a 'Hello World!' example written using Awk in Linux. You can compare it to this example for Windows.

AWK Windows Examples

Okay, here's the first; a simple Hello world example.

awk "BEGIN { print \"Hello world!\" }"

The above program will print Hello world! on the screen.

Linux users should notice the use of double quotation marks at the beginning & end of the script. Also notice how the quotations in the braces have had to be 'cancelled-out' with backslashes.

If anyone wants to know why I've become interested in Awk, it was based on me reading this thread on the Ubuntu Forum.

AWK, GAWK, MAWK etc...

I'd been hearing about 'awk' for a longtime on the Ubuntu forum. It's a simple command-line tool that you can use for searching through text files. I've just downloaded the Windows version which can be found here.

The biggest difference between the Linux version & the Windows version so far has been in how you enter quotation marks for the tasks.

Single for Linux '
Double for Windows "

I'll try & post some usage examples later on.
