Oracle Different output for awk command on Linux & HP-UX
I am using an awk command to extract a particular portion of a string. Below is the command and its output on a Linux system:

Code:
oracle@host1:/tmp [default] (/home/oracle)
$uname -a
Linux host1 2.6.32-279.39.1.el6.x86_64 #1 SMP Fri Nov 15 05:38:26 EST 2013 x86_64 x86_64 x86_64 GNU/Linux

oracle@host1:/tmp [default] (/home/oracle)
$echo "/u01/app/oracle/product/11.2.0.3/bin/tnslsnr;LISTENER;-inherit"|awk -F'/' '{for(i=1;i<NF;i++)NF=6;print $0}'|tr ' ' '/'
/u01/app/oracle/product/11.2.0.3


But the same command doesn't give desired output on an HP-UX system.
Below is the output from HP-UX System

Code:
[default](host2)/home/oracle-> uname -a
HP-UX host2 B.11.31 U ia64 1553842798 unlimited-user license

[default](host2)/home/oracle-> echo "/u01/app/oracle/product/11.2.0.3/bin/tnslsnr;LISTENER;-inherit"|awk -F'/' '{for(i=1;i<NF;i++)NF=6;print $0}'
/u01/app/oracle/product/11.2.0.3/bin/tnslsnr;LISTENER;-inherit
[default](host2)/home/oracle->

Can you guys help me understand why this command is not working on HP-UX. Also how do i get same result on HP-UX

I don't know anything about HP-UX, but your awk- version might not like the NF assignment. Try
Code:
echo "/u01/app/oracle/product/11.2.0.3/bin/tnslsnr;LISTENER;-inherit"|awk -F'/' -vOFS=\/ '{print $1,$2,$3,$4,$5,$6}'

Since you haven't changed anything to reconstruct the line, you get the output. Try $1 = $1
Code:
echo "/a/b/c/d/e/f/g/r/d/c/g" | awk -F '/' '{NF=6; $1=$1}1' OFS=/

Hi Srinishoo,
Can you please explain me your command
what does $1=$1}1' mean in the below code?

Code:
echo "/a/b/c/d/e/f/g/r/d/c/g" | awk -F '/' '{NF=6; $1=$1}1' OFS=/

On Linux you're most likely running mawk or GNU awk, both of which will re-calculate $0 if you assign to a field (or change NF, although that might depend on the version).

Whatever HP-UX is using probably does not (AIX awk doesn't, for instance) - you'd need to output the fields individually as RudiC suggested.

One more command, can someone help me in modifiying this command to work on HP-UX system

On Linux:

Code:
#->  echo "/u01/app/oracle/diag/tnslsnr/hpuxdgl1/listener/alert/log.xml"|awk -F'/' '{for(i=1;i<=NF;i++) if ($i ~ /diag/) NF=i;print $0}' OFS=/
/u01/app/oracle/diag

On HP-UX

Code:
$ echo "/u01/app/oracle/diag/tnslsnr/hpuxdgl1/listener/alert/log.xml"|awk -F'/' '{for(i=1;i<=NF;i++) if ($i ~ /diag/) NF=i;print $0}' OFS=/
/u01/app/oracle/diag/tnslsnr/hpuxdgl1/listener/alert/log.xml

Please ignore my latest query..i think i could figure out the way get same result on HPUX

Code:
 echo "/u01/app/oracle/diag/tnslsnr/hpuxdgl1/listener/alert/log.xml"|awk -F'/' '{for(i=1;i<=NF;i++) if ($i ~ /diag/) NF=i;$1=$1}1' OFS=/
/u01/app/oracle/diag

Srinishoo,

Your solution is working for me, but can you please explain me what does $1=$1 stand for ?

When you are printing the entire line, even though you make changes to the number of fields, you have to make changes within the line to reflect new number of fields
Here, $1=$1 is assigning the value of first field to the first field...
You can replace that part with $2=$2 as well
