I am building a script that will execute programs using records/fields in a file as arguments.
Before I start testing that, I am working on reading the file properly and using printf to display the fields in the file.
I used typeset to format my output.
Now all I need is to figure out how to... (1 Reply)
Hello.
I have got 3 unix boxes A B C. Box A is being used to prepare some reports. After the reports generation, Box A sftp the reports to Box B and Box C. When I look at the report in Box B and Box C. The reports are different. In Box B, I see using od -x command there is CRLF (\r\n) at the end... (7 Replies)
I am trying to convert a txt file that includes one long string of data. The lines are separated with hex value 7C (for pipe).
I am trying to process this file using SQR (Peoplesoft) so I thought the easiest thing to do would be to replace the eol char with a CRLF in unix so I can just... (4 Replies)

1. The problem statement, all variables and given/known data:
write a script asciiFix.sh that takes an arbitrary number of file paths from the command line and carries out the same analysis on each one. If a file is not Windows ASCII, your script should do nothing to it. For each file that is... (7 Replies)
I need to append |\r\n (a pipe character and CRLF) at end of each record in Unix to all records where they are not already present.
So first check for the presence of |\r\n and if absent append it else do nothing (3 Replies)
OK below is what my sample file looks like. I need to sort by the Primary Key ie: {1:F01SAESVAV0AXXX0466020126} in the first record. Record seperator is $.

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.
