Thanks Santiago. I need to pass in a variable into the while loop. The values in $OPTPARMS will change every run.
So
before the while loop should work, right?

I had a file with 150k records in it and I ran a tr on it to remove all new lines/CR which created one large record(whoops). Is there a way to add a \n after every 39th character without using 'dd' to turn it back into the original format?
dd is way to slow.
shell is ksh. (1 Reply)

Hi,
how can I join given arguments (not starting from the first one) to form one string, each argument separated by a space. For example, out of 5 given arguments, I'll like to start joining from the 3rd to the last. In python there exists something like ' '.join(sys.argv) and it starts joining... (5 Replies)
Hi all, I have a requirement where I am taking the first argument as argument name and storing the second argument in argument name as value.

Hello Community!
Let's say that we have some script which counts its arguments number:
arguments_count.sh:
#!/bin/sh
echo "Number of arguments="$#and some test script:
test.sh:
#!/bin/sh
my_args="1 2 3 '4 5' 6"
echo "Count of arguments when using my_args:"
./arguments_count.sh $my_args... (12 Replies)
Hi. I have a piece of code that reads and parses command line options. I'd like to alter it slightly to read from a string (that's set elsewhere in the script) rather than directly from the command line (arg). Can somebody show me how to do this? Many thanks.
My code is as follows:

io::async::signal
IO::Async::Signal(3pm) User Contributed Perl Documentation IO::Async::Signal(3pm)NAME
"IO::Async::Signal" - event callback on receipt of a POSIX signal
SYNOPSIS
use IO::Async::Signal;
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $signal = IO::Async::Signal->new(
name => "HUP",
on_receipt => sub {
print "I caught SIGHUP
";
},
);
$loop->add( $signal );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a particular POSIX signal is received.
Multiple objects can be added to a "Loop" that all watch for the same signal. The callback functions will all be invoked, in no particular
order.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_receipt
Invoked when the signal is received.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
name => STRING
The name of the signal to watch. This should be a bare name like "TERM". Can only be given at construction time.
on_receipt => CODE
CODE reference for the "on_receipt" event.
Once constructed, the "Signal" will need to be added to the "Loop" before it will work.
