Shell Programming and Scripting

No that won't work. The first awk is to clean empty lines so that they are only empty lines. It is to be completed before the file is read a second time to determine where a record starts and where it ends. RS= separates on the basis of two or more consecutive newlines. I do not understand why that would not work. Only prints the headers, what headers do you mean?
The "$1" inside the shell script is the first parameter on the command line of the script (for example Script.sh). So ./Script.sh inputfile > output would make "$1" inside the script equal to "inputfile" .

I've tested again, I realized that I was sending in wrong way the script, you've clarified with you example. Thank you it works now!!!

I meant the headers defined in BEGIN{} statement.

A question.

The way the script works now "./Script.sh inputfile > output" becomes in a executable script or not, if not how would be executable and how would be the way to execute it?

Many thanks, I think that must be the lasts questions, I've learned several new things with your answers and algorithm. Many thanks.

Hi, to make a script executable, have a look at man chmod
