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

No.  The command should be:
$ tr -sc 0-9\\n ' ' < hostname_list | awk '{ k = 0; for (i = 0; k < 4 && ++i   
file | command2 file
As a consequence, it is possible that "file" does not even exist when  
'command2' tries to read it.  'command2' would then end with an error.
