hi all,
I generally give an awk command to print multiple columns like this:
awk -F~ '{OFS=",";print $1,$2,$3,$4,$5,$6,$7,$8,$9,$10,$11,$12,$13}' test.txt
can't we give a range like :
awk -F~ '{OFS=",";print $1-$13}'
( I know this will subtract column 13 from 1)
or awk -F~... (1 Reply)
I want to print between the range two patterns if a particular pattern is present in between the two patterns. I am new to Unix. Any help would be greatly appreciated.
e.g.

Hi, Please read the whole thread.
I have been working on this script below. It works fine, feel free to copy and test with the INPUT File below as well.

To match range, the command is:
awk '/BEGIN/,/END/'
but what I want is the range is printed only if there is additional pattern that matches in the range itself? maybe like this:
awk '/BEGIN/,/END/ if only in that range there is /pattern/'
Thanks (8 Replies)
im using the following code to grab data, but after the data in the range im specifying has been grabbed, i want to count how many instances of a particular pattern is found?

Hi all,
I have searched and searched, but I have not found a solution that quite fits what I am trying to do.

io::async::pid
IO::Async::PID(3pm) User Contributed Perl Documentation IO::Async::PID(3pm)NAME
"IO::Async::PID" - event callback on exit of a child process
SYNOPSIS
use IO::Async::PID;
use POSIX qw( WEXITSTATUS );
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $kid = $loop->fork(
code => sub {
print "Child sleeping..
";
sleep 10;
print "Child exiting
";
return 20;
},
);
print "Child process $kid started
";
my $pid = IO::Async::PID->new(
pid => $kid,
on_exit => sub {
my ( $self, $exitcode ) = @_;
printf "Child process %d exited with status %d
",
$self->pid, WEXITSTATUS($exitcode);
},
);
$loop->add( $pid );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a process exits.
For most use cases, a IO::Async::Process object provides more control of setting up the process, connecting filehandles to it, sending data
to and receiving data from it.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_exit $exitcode
Invoked when the watched process exits.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
pid => INT
The process ID to watch. Must be given before the object has been added to the containing "IO::Async::Loop" object.
on_exit => CODE
CODE reference for the "on_exit" event.
Once the "on_exit" continuation has been invoked, the "IO::Async::PID" object is removed from the containing "IO::Async::Loop" object.
METHODS
$process_id = $pid->pid
Returns the underlying process ID
$pid->kill( $signal )
Sends a signal to the process
