Interpreting multiple values from a variable
Hi,

I am writing a shell script which will check the status of a resource in a cluster and then display nicely to a user running the script at command line.

Basically the script runs a status command and then pulls certain keywords from the return and then should display a concise status.

My current code:

Code:
appVstatus=`scstat -g | grep ITM | grep $DC | awk '{print $2 "|" $5}'`
oldIFS="IFS"
IFS='|'
echo $appVstatus
 
    echo $appVstatus | (while read -r processname status; do
    echo "$processname is $status"
    done)

This results in :

Code:
CREST06QM_A_ITM Online
CREST06_HUBC3_A_ITM Online
CREST06_HUBC4_A_ITM Online
CREST06QM_A_ITM Online is 
CREST06_HUBC3_A_ITM Online is 
CREST06_HUBC4_A_ITM Online is

What I am actually looking for is:

Code:
CREST06QM_A_ITM Online
CREST06_HUBC3_A_ITM Online
CREST06_HUBC4_A_ITM Online
CREST06QM_A_ITM is Online 
CREST06_HUBC3_A_ITM is Online 
CREST06_HUBC4_A_ITM is Online

Any ideas would be gratefully received. I'm going round in circles on this one!

Well I dont unsertans how you can achieve the first three lines of your desired output, but a quick look at your code makes me think CREST06QM_A_ITM Online is $processname and so the output I dont understand is where have the "is" passed in those lines (based on your code, if no $status is found, you should be left with "is" )

Try read -r processname status RESTto avoid the rest of the line being read into the status variable.

vbe - the first 3 lines are coming from the echo $appVstatus line (this was just a debug line to dislay what the variable contained).

RudiC - Still the same result.

It looks like the 2 prints in the AWK statement are being read into processname instead of the first to processname and the second to status

Do you require information about resources or resources group or both ?
For resource groups :
Code:
 scstat -g | awk '$1 ~ /Group/ && $4 ~ /Online/ { print "RG" FS $2 FS "is online on host" FS $3 } '

For resources :
Code:
scstat -g | awk '$1 ~ /Resource:/ && $4 ~ /Online/ { print "Resource" FS $2 FS "is online on host" FS $3 } '

If you require both, i can work something out...

I overlooked your setting IFS to "|" so my proposal was doomed to fail... Please post the output of scstat -g as I don't have that, so we can offer sensible help.
