Dear Friend,

You can use the following code

use strict;

use warnings;
my ($var,$var1);
open (FH,"<file");
while($var=<FH>)
{
     chomp($var);
     if($var=~/\/dev\/sap/)
         {
           $var1=<FH>;
           $var=$var. " $var1";
         }
     print "$var\n";
}

alister your solution will work only for the first occurrence.
dennis.jacob your solution will work only on next line.
Try on this data sample:

/dev/xxx oracle test
/dev/sap
9999 000 88 99
/dev/xxx oracle test
/dev/sap
9999 000 88 99
9999 000 88 99

danmero, I did not get you. I think the output which I am getting for the sample data is correct as per my understanding.

/home/usr1 >awk ' _s { print _s,$0; _s="";next; }NF==1 { _s=$0; }!_s' < file
/dev/xxx oracle test
/dev/sap 9999 000 88 99
/dev/xxx oracle test
/dev/sap 9999 000 88 99
9999 000 88 99
/home/usr1 >cat file
/dev/xxx oracle test
/dev/sap
9999 000 88 99
/dev/xxx oracle test
/dev/sap
9999 000 88 99
9999 000 88 99

Hi, danmero:
You are correct. It works just as I intended. I see nothing in the original post suggesting that anything more is required, but kudos to you for going above and beyond. :slight_smile:

Regards,

Cheers danmero, I didn't understand your script until I debug it.
