Hello,

$USER - `grep $USER /etc/passwd | awk -F: '{ print $5 }' | awk -F, '{ print $1 }'`
Thanks

Hi all,
I'm trying to split fields separated by multiple characters :
Here's the string :
"toto"||"ta|ta"||"titi"
Here's what I want :
"toto"||"ta|ta"
I tried several ways, but it seems that my delimiter || is not working :
echo "\"toto\"||\"ta|ta\"||\"titi\"" | awk 'BEGIN... (4 Replies)
I have several hundred files that look like this:

If I use the statement ls | awk '{x=$0;gsub("","",x)
I see that all characters other than 0-9 are eliminated but how do I eliminate all characters including numbers after the "."
In my mind I... (1 Reply)

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
