Here I am trying to get a value. My code is like this 

 
foreach my $min (20 .. 29)
{
        foreach my $sec (@seconds)
        {
                my $SMPP_count = split (/[\s]/,(chomp(`cut -d "|" -f 1
+,10,13 SMSCDR*$date$hour$minute*.log |grep "Submit|SMPP" |grep "$hour
+:$min:$sec" |sort |uniq -c`)))[0];
                print $SMPP_count;
        }
}

 cut -d "|" -f 1,10,13 SMSCDR*$date$hour$minute*.log |grep "Submit|SMPP" |grep "$hour:$min:$sec" |sort |uniq -c`

I will return

 20 Wed Sep 23 06:20:02 2015|Submit|SMPP

In this statement a new line is presented in the last. to remove that I am using chomp. For getting the value I am using split with "\s" (space separator). But its showing error. 

 

Can't modify quoted execution (``, qx) in chomp at second.pl line 24, 
+near "`cut -d "|" -f 1,10,13 SMSCDR*$date$hour$minute*.log |grep "Sub
+mit|SMPP" |grep "$hour:$min:$sec" |sort |uniq -c`)"
