Fun awk script. Looking to a possible improvement

Steven E. Protter — Thu, 01 Jul 2010 15:07:35 GMT

I had a need to display some hardware information to update some documentation.

So I created this: http://www.hpux.ws/?p=149

ioscan -fnkCfc | awk ‘/fcd/ {getline;fcd=$NF;print fcd,$2 }’ | while read -r fdev
do
fcmsutil $fdev | awk ‘/Hardware / {print $5}’
fcmsutil $fdev | awk ‘/World / { print $7}’
done

I'm pushing myself to be more awkful and am wondering how I would go about combining the two fcmsutil statements and running fcmsutil only once to save on cpu usage. Not that I should care on a superdome, but I need to do this for work and I find this extremely fun to do.

What I'm thinking is a little awk for loop to roll through and getline and then select the ouput I want.

My awk guru is out of the office today, so I will first do the job and actually update the dcoumentation and then continue to hack around with the awk.

Hi Sep:

# cat ./ascript
#!/usr/bin/sh
ioscan -kfnC fc | awk '/fcd/ {getline;fcd=$NF;print fcd,$2}' | while read -r fdev
do
fcmsutil ${fdev} | awk '/Hardware / {print $5};/World / { print $7}'
done

...that is, simply specify your multiple pattern matches and their statements as shown.

Regards!

Didn't realize it was that simple.

Happy to put you 10 points closer to me JRF, you are truly the more gifted admin.

To earn another 10, I was thinking I wanted to format the data

PATH WWN node WWN port WWN port WWN node

I am updating the blog after I test and making an attempt to format the output.

The formatting makes it easier to create live documanation.

Working on something here.

ioscan -kfnC fc | awk '/fcd/ {getline;fcd=$NF;print fcd,$2}' | while read -r fde
v
do
fcmsutil ${fdev} | awk '/Hardware / {print $5};/World / { print $7}' | awk '
{printf "%s %s %s %s %s\n",$1, $2, $3, $4, $5}'

The line break is not working out here.

Hi (again) SEP:

Perhaps formatted like this:

# ./ascript
#!/usr/bin/sh
ioscan -kfnC fc | awk '/fcd/ {getline;fcd=$NF;print fcd,$2}' | while read -r fdev
do
fcmsutil ${fdev} | \
awk '/Hardware Path/ {PATH=$5};
/N_Port Node/ {NNODE=$7};
/N_Port Port/ {NPORT=$7};
/Switch Port/ {SPORT=$7};
/Switch Node/ {SNODE=$7};
END{print PATH, NNODE, NPORT, SPORT, SNODE}
'
done

Regards!

Thanks JRF.

I almost had it.

fcmsutil $fdev | awk â /Hardware / {print $5;next}
/World/{ print $7;next}â

Shalom,

ITRC or your browser or notepad tool ate your output Victor.

fcmsutil $fdev | awk '/Hardware / {print $5;next}
/World /{ print $7;next}'

That is how I interpret your entry.

I'm posting 8 points to the response because you were a great boss.

This issue is resolved, but I'm totally willing to see and reward other approaches.

You interpret it correctly. Please, without points.

Hi (again) SEP:

As Victor showed, we should really stop matching as soon as a pattern is found. Adding 'next' to the action statement for each pattern is one way. Another is to write a cascading 'if/else':

# cat ./ascript
#!/usr/bin/sh
ioscan -kfnC fc | awk '/fcd/ {getline;fcd=$NF;print fcd,$2}' | while read -r fdev
do
fcmsutil ${fdev} | \
awk '
{if (/Hardware Path/) {
PATH=$5
} else if (/N_Port Node/) {
NNODE=$7
} else if (/N_Port Port/) {
NPORT=$7
} else if (/Switch Port/) {
SPORT=$7
} else if (/Switch Node/) {
SNODE=$7
}
}
END{print PATH, NNODE, NPORT, SPORT, SNODE}
'
done

Regards!

Hello Steven,

Here is my fun - I hope - proposal:

ioscan -fnkC fc | awk '
/^fc/ {
getline
command = "fcmsutil " $NF
while ( command | getline line )
{
split ( line, item, " = " )
sub ( /^[[:space:]]+/, "", item[1] )
value[item[1]] = item[2]
}
close ( command )
printf ( "%-10s %20s %20s\n",
value["Hardware Path is"],
value["N_Port Node World Wide Name"],
value["N_Port Port World Wide Name"] )
}'

Sorry having no fcd devices but fc.
I trust you will adapt it.

Please be careful: there are spaces surrounding the equal sign in the split function.

Have a nice day,

Jean-Philippe

Steven,

Here is another fun program, with same output format: (PATH, NNODE, NPORT, SPORT, SNODE ):

do
fcmsutil ${fdev} |awk -F "=" '/Hardware/ || /World/ {print $2}'| xargs| awk '{print $5,$1,$2,$3,$4}'
done

Sample output will look like below:
0/0/4/1/0 0x50060b000060a987 0x50060b000060a986 0x2202000dec277f00 0x27e4000dec0d3081

Regards,
Raj.
