Hi,
I have a developer that is trying to start a script with sh "scriptname". In the script, he is specifying #!/usr/bin/ksh as the command interpreter. For some reason sh is ignoring the #!/usr/bin/ksh. We are running Solaris 8. Does anyone have any ideas what could be causing this? Here... (3 Replies)

Q1. I understand that /usr/local/bin means I can install/uninstall stuff in here and have any chance of messing up my original system files or effecting any other users. I created this directory myself.
But what about the directory I didn't create, namely /Users/m/bin? How is that directory... (1 Reply)
Hi Experts,
I found that the same commands(sort, du, df, find, grep etc.) exists in both dir.
What is the difference to use them?
i.e: to use xpg4/bin/grep and usr/bin/grep
My OS version is SunOS 5.10

Some question about the usage of shell scripts:
1.) Are the commands of the base shell scripts a subset of bash commands?
2.) Assume I got a long, long script WITHOUT the first line.
How can I find out if the script was originally designed für "sh" or "bash"?
3.) How can I check a given... (3 Replies)

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
