combinig o/p

[Soul_1]

Hi all,

i wrote one script to get the node details.

#!/usr/bin/sh
#Script to check the node details
Node=$(/opt/OV/bin/ovtopodump -lr|grep "NODE LABEL"|awk '{print $3}')
Int=$(/opt/OV/bin/ovtopodump -lr|grep "NUMBER OF INTERFACES")
Detail="$Node $Int"
echo "$Detail \c\n"
_______________________________
The o/p of this command is will be
Node=$(/opt/OV/bin/ovtopodump -lr|grep "NODE LABEL"|awk '{print $3}')

xyz.co.in
yyy.co.in
sss.co.in
ttt.co.in

and o/p of second command Int=$(/opt/OV/bin/ovtopodump -lr|grep "NUMBER OF INTERFACES")
is
interfaces 30
interfaces 120
interfaces 12
interfaces 44

what is my req is i want to display the o/p in one line

i.e
xyz.co.in interfaces 30
yyy.co.in interfaces 120
sss.co.in interfaces 12

but i am getting o/p as
xyz.co.in
yyy.co.in
sss.co.in
ttt.co.in interfaces 30
interfaces 120
interfaces 12
interfaces 44


please guide me to achieve this .


Thanks to all in advance

there is ery simple utility called paste

paste file1 file2

outpur will be the one you want.

Hi ,

Thanks for the information.
It would be helpful if we combine the o/p without redirecting the result to another one and combibining it.


any way that was working.Thanks Once again

[Kapil Jha]

not sure but u can do like

Detail= paste $Node $Int
echo "$Detail \c\n"


this should work.

Hi,

It is not working, as it is not able to find the files.


Thanks & Regards,

You can probably do that if you use awk on the output of:
/opt/OV/bin/ovtopodump -lr | grep -e "NODE LABEL" -e "NUMBER OF INTERFACES"

Can you provide a sample of that that looks like?

[TARUN SHARMA_1]

Just give a small o/p of (/opt/OV/bin/ovtopodump -lr to understand it better.

[Viktor Balogh]

try something like this:

# /opt/OV/bin/ovtopodump -lr |
awk '/NODE LABEL/ {printf $3"\t"}
/NUMBER OF INTERFACES/ {print $0}'

maybe it's not perfect because it is untested. But there's no need to run ovtopodump twice and grep can also be done with awk. Tailor it to your own needs.

[Dennis Handly]

>Viktor: try something like this:

Assuming they come out in that order, you could also use a variable so you only have one print:
... | awk '
/NODE LABEL/ { NODE = $3 }
/NUMBER OF INTERFACES/ { print NODE, $0 }'

hi

Thanks all,

can you please tell me how this command works

1. /opt/OV/bin/ovtopodump -lr|awk '/NODE LABEL/ { NODE = $3 } /NUMBER OF INTERFACES/ { print NODE, $0 }'

2.
/opt/OV/bin/ovtopodump -lr | awk '/NODE LABEL/ {printf $3"\t"}/NUMBER OF INTERFACES/ {print $0}'

It would be great helpful if you explain how this works.

Thanks a lot

both are giving the desired o/p.

>1. awk '/NODE LABEL/ { NODE = $3 } /NUMBER OF INTERFACES/ { print NODE, $0 }'

This saves field3 of every line that has "NODE LABEL". When it finds a line with "NUMBER OF INTERFACES", it first prints the saved NODE, then a space (the variable OFS), then the current line.

>2.awk '/NODE LABEL/ {printf $3"\t"}/NUMBER OF INTERFACES/ {print $0}'

This finds the same two lines. For the first, it prints field3, then a tab. For the second, it prints the line, appended to the first printf (that doesn't have a newline).

Both depend on the ordering of the original two lines.

[Viktor Balogh]

awk '/search_pattern/ {do this if pattern found}'

with the 'print' awk statement you can write the n'th field by $n. The fields are separated by whitespaces in default.

so the following means:

awk '/NODE LABEL/ {printf $3"\t"}
/NUMBER OF INTERFACES/ {print $0}'

if "NODE LABEL" is found in the line, print the 3rd field, and if "NUMBER OF INTERFACES" matches print the whole line (that's $0)

And do not forget about the quotes (') all around the awk statement, without these the words with $ would be substituted by your shell.

The other query is the same, I hope you can figure that out.
