Convert .sh script into perl

Shell Programming and Scripting

Good afternoon to you all

I really need your help

I have the following script developed in .sh and I need to convert it into perl. Can someone help me do it please?

Here�s the script:

##############################################

##############################################

cat /var/www/monitor/scripts/TestProbes/probelist.txt | while read probe

        do

{
perl /var/www/monitor/scripts/slabb/getQosData.pl -s DNS -m Availability -c $probe
} >> /var/www/monitor/scripts/TestProbes/Probes/"$probe".txt


                      if [[ -s /var/www/monitor/scripts/TestProbes/Probes/"$probe".txt ]] ; then

 echo "Probe has data"

                      else

echo "Probe has no data" 


                    fi

        rm /var/www/monitor/scripts/TestProbes/Probes/"$probe".txt
        touch /var/www/monitor/scripts/TestProbes/Probes/"$probe".txt
        chmod 777 /var/www/monitor/scripts/TestProbes/Probes/"$probe".txt


        done

Why?

All you are doing is running basic commands - half of which I can't understand what or why.

What will perl give you here?

I need to integrate it on an application that only interprets perl.

The script is very simple as you said. It�s only a condition checking if a specific file is empty or not. I just want to convert it into perl.

Few thing that you can start with to convert this into perl -

1) File opening /Reading from file/Writing to a file/Executing a script
2) Condition checking (file exist ?)

You can open the file for reading in perl using
open(FHI,"</var/www/monitor/scripts/TestProbes/probelist.txt");

You can read data from this file (alternate of while read line in unix)
while(defined(<FH>))
{

}

How you will execute the perl script in side it ?
system(/var/www/monitor/scripts/slabb/getQosData.pl -s DNS -m Availability -c $probe);

How you will write the contents to a file $probe.txt ??
open(FHO,">/var/www/monitor/scripts/TestProbes/Probes/$probe.'.txt'");

You can check the file exist or not using

if (- e $probe)
{
print "Probe exist\n";
}
else
{
print "Probe missing \n";
}

---Just assemble this idea into your perl script --
