I am using the following Perl script to write out a shell script:
#!/usr/bin/perl -w
$incr=0.1;
$dist=5.1;
my $filename = 'job-1.sh';
open (my $BATCHFILE, '>', "$filename");
while ($dist <= 15) {
print $BATCHFILE
"
YOYO -O -i min_mdin.$dist
";
$dist += $incr;
}
close ($BATCHFILE);
The job-1.sh file should contain the following lines:
YOYO -O -i min_mdin.5.1
YOYO -O -i min_mdin.5.2
……
YOYO -O -i min_mdin.15
However, some files are printed as follows:
YOYO -O -i min_mdin.6.49999999999999
YOYO -O -i min_mdin.6.59999999999999
This problem occurs only when the increment is 0.1. An increment of 0.2 or 0.25 do not give this error.
Here's what's happening:
https://floating-point-gui.de
As a quick fix try something like this:
#!/usr/bin/perl -w
$incr=1;
$dist=51;
while ($dist <= 150)
{
print $dist/10 . "\n";
$dist += $incr;
}
Or this:
#!/usr/bin/perl -w
$incr = 0.1;
$dist = 5.1;
while ($dist <= 15)
{
print sprintf("%.2f",$dist) . "\n";
$dist = $dist + $incr;
}

You have a quoting problem - you've used single quotes when the string includes a shell variable:
if /bin/grep -qi "^$EXTEN;" $OFFLINE; then
/bin/sed -i '/^$EXTEN;/d' $OFFLINE
fi
Try using double quotes instead:
if /bin/grep -qi "^$EXTEN;" $OFFLINE; then
/bin/sed -i "/^$EXTEN;/d" $OFFLINE
fi

SSH containers should be created on Remote machines.An SSH container is just a Fabric container that is running on a remote host on your local network,
where that host is accessible through the SSH protocol. This section describes some basic administration tasks for these SSH containers.
Please refer https://access.redhat.com/documentation/en-us/red_hat_jboss_fuse/6.3/html/fabric_guide/chapter-fabric_container#ContSSH
If you want to create containers on the same machine (local host) create child containers
https://access.redhat.com/documentation/en-us/red_hat_jboss_fuse/6.3/html/fabric_guide/chapter-fabric_container#ContChild
Creating ssh container
fabric:container-create-ssh --host remotehost --user user1 --password pass1 --jvm-opts="-Djava.rmi.server.hostname=remotehost" --profile fabric fabric-eu03
Although this script works, I am not happy about the excess of nested quoting, which makes the script very fragile and difficult to modify.
The script consists basically of parallel followed by a filter test argument followed by command arguments.
