You didn't say what the problem was. This code looks OK to me:
It looks like you have tab-delimited data AND space-delimited data, and therefore what you're trying is:
"If the line ends in two consecutive tabs (making the last field and next-to-last field empty) then parse the first field by spaces. With 4 words, print the first three; with 3 words, print the first two; with two words, print only the last."
That's a really weird way to parse. Maybe you could post some same input data and a sample of your desired output?
And yes, you should be able to this this with one awk statement. You don't even need the grep:
Actually I got a list of file end with *.txt
I want to use the same command apply to all the *.txt
Thus I try to find out the fastest way to write those same command in a script and then want to let them run automatics.
For example:
I got the file below:
file1.txt
file2.txt
file3.txt... (4 Replies)

Perl::Critic::Policy::ControlStructures::ProhibitUnreachUserCContributed Perl DPerl::Critic::Policy::ControlStructures::ProhibitUnreachableCode(3)NAME
Perl::Critic::Policy::ControlStructures::ProhibitUnreachableCode - Don't write code after an unconditional "die, exit, or next".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
This policy prohibits code following a statement which unconditionally alters the program flow. This includes calls to "exit", "die",
"return", "next", "last" and "goto". Due to common usage, "croak" and "confess" from Carp are also included.
Code is reachable if any of the following conditions are true:
o Flow-altering statement has a conditional attached to it
o Statement is on the right side of an operator "&&", "||", "//", "and", "or", or "err".
o Code is prefixed with a label (can potentially be reached via "goto")
o Code is a subroutine
EXAMPLES
# not ok
exit;
print "123
";
# ok
exit if !$xyz;
print "123
";
# not ok
for ( 1 .. 10 ) {
next;
print 1;
}
# ok
for ( 1 .. 10 ) {
next if $_ == 5;
print 1;
}
# not ok
sub foo {
my $bar = shift;
return;
print 1;
}
# ok
sub foo {
my $bar = shift;
return if $bar->baz();
print 1;
}
# not ok
die;
print "123
";
# ok
die;
LABEL: print "123
";
# not ok
croak;
do_something();
# ok
croak;
sub do_something {}
CONFIGURATION
This Policy is not configurable except for the standard options.
