[Trisquel-users] Re : How can one capture the "Failed to resolve" output to console during an nMap scan ?

The tutorial you found is excellent.  It never presents the execution of an  
external command line from within AWK.  It is actually possible, using the  
"system" statement.  You apparently only want to do do that (calling other  
AWK programs, which themselves call 'nmap', etc.).  I very much doubt it is  
what you need.  I also very much doubt you did the tutorial.  You are  
basically asking (not with a correct syntax) to execute two AWK programs on  
fixed input files as many times as there are lines processed by the main AWK  
program.  You probably only want to post-process the output of the main AWK  
program (not that I really understand what you try to achieve, though).

And before learning AWK, you should learn the basics of the Shell  
(redirections, piping, etc.).
