Don't have to be before the main function, the main function can get called with either the file or passed variables.
The problem I had with the script is I want an easy way to say, if values are passed i.e.:
Then just send those and don't read the ./config.cfg file. If they are empty then read the file and loop (as would be mutiple iterations in there).
So the second solution I have works (and is what I am using). What I wondered, can you have the while loop enabled depending on a condition, and if that condition is not met then just run the code which would of been in while loop.
I know I have acieved this in the second example, but from PHP I would of been able to solve it using the first method. Shell seems to require loops / cases to have to be comepleted and not cross into other if / while loops (if that makes any sense)
Hi all,
I plan to write a shell script to inform users on their task when certain condition met.
example: If a
then email user on action a
else
email user on action b.
I'm pretty new in scripting, appreciate any suggestions.
Thanks. (4 Replies)

I want to abort script if input variable matched first field in any line of a file.
#!/bin/sh
read INPUTVAR1
awk "{if(\$INPUTVAR1 == $1) x = 1} END {if(x==1) print \"I want to abort script here\"; else print \"OK\"}" /etc/some.conf
I tried "exit" and system("exit") but no luck. (1 Reply)
Hi All,
Seeking for your assistance to print all the specific field when the condition met.
Ex:
file1.txt
1|203|3|31243|5341|6452|623|22|00|01
3|45345|123214|6534|3423|6565|643|343|232|10
if field 1 = 1 and field 3 = 3 and field 5 = 5341 and field 6 = 6452
it will print from $1 to $10.... (2 Replies)

In the below I can not seem to add a line that will add Not low if the statement in bold is not true or meet. I guess when the first if statement is true/meet then print low, otherwise print Not low in $(NF + 1). I am not sure how to correctly add this. Thank you :).

io::async::test
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.
