Hello everyone,
how can I send output to the screen from a running script or tcl, in such a way that if a loop is executing I will see the rolling counter on my screen as the records are processed in the loop. I do not want the screen to scroll, though. In other words can a var's value be painted... (2 Replies)
Say I have (in psuedocode)
For i=1 to 10
tar cvfb /... 5*i /junk(i)
end
What I mean is that I want each successive for loop to have the block size parameter be 5 times the current counter. This isn't my actual code, just a stupid example...So the question is how do I descrive that parameter... (2 Replies)
The scenario is like this :
I need to read records from a file one by one and increment counter1, if a certain field matches with a number say "40"..the script should increment the counter2 and also extract a corresponding field from the same line and adding them one by one and redirecting the the... (5 Replies)
Hello Everyone,
I'm in need of assistance on creating a script with a counter on a certain string.
Basically this script opens a log file and displays certain log data. There are two key words in the log. START and FINISH. In between the START and FINISH is a variable ACTNUMBER. It will... (1 Reply)

Hello,
I have currently coded a bash script below in which it does the following:
# Archives compressed file from another location.
Basically it moves *.gz files to another location.
The script also sends an email whenever a new compressed file is placed. This is the issue that i... (5 Replies)
Hi!
Can anyone explain this? The counter CDR_count should go on forever, but it suddenly resets at every step of the FOR loop (I know this because $_file has exactly 378 records). However, the counter reset is OUTSIDE the FOR loop. What's going on??
#!/bin/bash
if || ; then
echo

#!/usr/bin/ksh
c=0
while ]; do
echo /tmp/unex NOT found, iter : $c;
((c = $c + 1));
sleep 2;
done
so, the above counter doesn't work, already tried both -lt & -gt, and changed || to &&
so what am I missing?
Thanks in advance (5 Replies)

IO::Async::Test(3pm) User Contributed Perl Documentation IO::Async::Test(3pm)NAME
"IO::Async::Test" - utility functions for use in test scripts
SYNOPSIS
use Test::More tests => 1;
use IO::Async::Test;
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
testing_loop( $loop );
my $result;
$loop->do_something(
some => args,
on_done => sub {
$result = the_outcome;
}
);
wait_for { defined $result };
is( $result, what_we_expected, 'The event happened' );
...
my $buffer = "";
my $handle = IO::Handle-> ...
wait_for_stream { length $buffer >= 10 } $handle => $buffer;
is( substr( $buffer, 0, 10, "" ), "0123456789", 'Buffer was correct' );
DESCRIPTION
This module provides utility functions that may be useful when writing test scripts for code which uses "IO::Async" (as well as being used
in the "IO::Async" test scripts themselves).
Test scripts are often synchronous by nature; they are a linear sequence of actions to perform, interspersed with assertions which check
for given conditions. This goes against the very nature of "IO::Async" which, being an asynchronisation framework, does not provide a
linear stepped way of working.
In order to write a test, the "wait_for" function provides a way of synchronising the code, so that a given condition is known to hold,
which would typically signify that some event has occured, the outcome of which can now be tested using the usual testing primitives.
Because the primary purpose of "IO::Async" is to provide IO operations on filehandles, a great many tests will likely be based around
connected pipes or socket handles. The "wait_for_stream" function provides a convenient way to wait for some content to be written through
such a connected stream.
FUNCTIONS
testing_loop( $loop )
Set the "IO::Async::Loop" object which the "wait_for" function will loop on.
wait_for( $condfunc )
Repeatedly call the "loop_once" method on the underlying loop (given to the "testing_loop" function), until the given condition function
callback returns true.
To guard against stalled scripts, if the loop indicates a timeout for 10 consequentive seconds, then an error is thrown.
wait_for_stream( $condfunc, $handle, $buffer )
As "wait_for", but will also watch the given IO handle for readability, and whenever it is readable will read bytes in from it into the
given buffer. The buffer is NOT initialised when the function is entered, in case data remains from a previous call.
$buffer can also be a CODE reference, in which case it will be invoked being passed data read from the handle, whenever it is readable.
