AWK: Backslash \ and forcing output not to go onto new lines
Dear all,
I am using Mac OSX, have been successfully written an awk script during the last days. I use the script to convert parts of a .dot-file into graphml code.
First question: Backslash
My .dot-code includes repeatedly the sign "\n".
I would like to search for this sign and substitute it.
This does not provide the effect:
I get as a result:
Neither does it work if I write
.
(Substituting "assumption" works without problems.)
Do you have any hint of how to get the sign "\n" substituted?
Second question: forcing output not to go onto new lines
I wonder if a simple way exists to tell awk to put a number of outputs onto the same line:
awk reads in from asource file a line word by word. i want to print some words, alter some and then print them, and again simply print some together with some additional information of mine ("info").
This operation acts on up to 80 words of a line. i want the out put (i.e. cleaned up words) to go on one line, without any linebreaks.
Hi,

Both of these fail. One has two form feeds, the second form leaves all the backslashes.

I have two large files (~250GB) that I am trying to remove the where GT: 0/0 or 1/1 or 2/2 for both files. I was going to use a bash with the below awk, which I think will find each line but how do I remove that line is that condition is found? Thank you :).

In the awk below which does execute I get output that is close, except for all the lines that start with a # are removed. Some lines have one others two or three and after the script adds the
ID= to the fields below the pattern in the awk, I can not seem to add the # lines back to the output. ... (5 Replies)
The awk below executes and produces the current output, which is correct, except I can not seem to include the header lines # and ## in the output as well. I tried adding !/^#/ thinking that it would skip the lines with # and output them but the entire file prints as is. Thank you :).

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
