Shell Programming and Scripting

Hello, this is my 1st post and really like what I see from this community so far. I have a script I am trying to create. This is what I have started:

#!/bin/sh

export JAVA_HOME=/hosting/products/WebSphereU01/java
/hosting/ogsa/ogsa-6.1.0.5/ObjectGrid/bin/xsadmin.sh -p 26572 -bp 26570 -ch nc3sz2ecmus02 -containers

The output is like this (truncated)

Container: CP03-A06-WXS_container_Profile_PTE03-nc3sz2ecmas10_C-0, Server:CP03-A06-WXS_container_Profile_PTE03-nc3sz2ecmas10, Zone:ZoneB
P:185 Primary
P:186 Primary
P:187 Primary
P:188 Primary
P:189 Primary
P:137 AsynchronousReplica
P:148 AsynchronousReplica
P:180 AsynchronousReplica
P:192 AsynchronousReplica
P:7 AsynchronousReplica
Container: CP03-A07-WXS_container_Profile_PTE03-nc3sz2ecmas10_C-0, Server:CP03-A07-WXS_container_Profile_PTE03-nc3sz2ecmas10, Zone:ZoneB
P:195 Primary
P:196 Primary
P:197 Primary
P:198 Primary
P:199 Primary
P:139 AsynchronousReplica
P:149 AsynchronousReplica
P:182 AsynchronousReplica
P:19 AsynchronousReplica
P:56 AsynchronousReplica

Num containers matching = 40
Total known containers = 40
Total known hosts = 8

I bolded the example iof the necessary data that I need.

So this is basically what I need for the script to do. The criteria of what I want the script to to do is return single values say a "1" or "0". I can either go with one of two scenarios, the 1st is:

If total hosts equal 27 and if total containers equals 135 or 136 – than assign a value of "0"; any other result a value of "1" should be assigned.

Or...

Add total number of host to total number of containers and if the result anything other than 162 or 163 then assigne a value of "1". Anything other than that assign a value of "0".

I appreciate any ideas and help you guys can lend to offer. I have tried awk, sed and if-then scenarios but haven't been able to get the logic right.

Pipe your output through awk:

Code:

shell_var=$( your-command | awk '
   /Total known containers/ { sum += $NF; next}
   /Total known hosts/ { sum += $NF; next; }
   END {
      printf( "%d\n", sum > 161 && sum < 164 ? 1 : 0 );
   }' )

If you really are using /bin/sh you'll need to use back-ticks, but everything else is the same.

Hmmmm, I tried running this but get some kind of error.

./hosts.sh
./hosts.sh[4]: 0403-057 Syntax error at line 9 : `)' is not expected.

I added the script as instructed.

#!/bin/sh
export JAVA_HOME=/hosting/products/WebSphereU01/java
/hosting/ogsa/ogsa-6.1.0.5/ObjectGrid/bin/xsadmin.sh -p 26572 -bp 26570
-ch nc3sz2ecmus02 -containers | awk ' {
/Total known containers/ { sum += $NF; next}
/Total known hosts/ { sum += $NF; next; }
END {
printf( "%d\n", sum > 161 && sum < 164 ? 1 : 0 );
}' )

where you added this $(

it should be there before $(/hosting/

I added the parenthesis (/hosting/ogsa/ogsa........

but then received this error.

./hosts.sh
Syntax Error The source line is 2.
The error context is
/Total known containers/ >>> { <<<
awk: 0602-502 The statement cannot be correctly parsed. The source line is 2.
awk: 0602-540 There is a missing } character.

You are missing the variable to assign the result to and the opening $(:

Code:

#!/bin/sh
 export JAVA_HOME=$( /hosting/products/WebSphereU01/java/hosting/ogsa/ogsa-6.1.0.5/ObjectGrid/bin/xsadmin.sh -p 26572 -bp 26570 -ch nc3sz2ecmus02 -containers | awk ' {
 /Total known containers/ { sum += $NF; next}
 /Total known hosts/ { sum += $NF; next; }
 END {
 printf( "%d\n", sum > 161 && sum < 164 ? 1 : 0 );
 }' )

If that still produces an error, use back-quotes like this:

Code:

#!/bin/sh
 export JAVA_HOME=` /hosting/products/WebSphereU01/java/hosting/ogsa/ogsa-6.1.0.5/ObjectGrid/bin/xsadmin.sh -p 26572 -bp 26570 -ch nc3sz2ecmus02 -containers | awk ' {
 /Total known containers/ { sum += $NF; next}
 /Total known hosts/ { sum += $NF; next; }
 END {
 printf( "%d\n", sum > 161 && sum < 164 ? 1 : 0 );
 }' `

Using backquotes is deprecated, but if you are indeed using the original Bourne shell (most UNIX flavours install bash as /bin/sh) then you'll need to use the back-quotes. Try with the first construct though.

Hard to say just from the error. Can you cut/paste your script as you executed it?

This is the error I received. I beleive there is an issue with the JAVE_HOME path which was modified. I have to set the environment in Java to execute this script.

./hst1
./hst1[2]: /hosting/products/WebSphereU01/java/hosting/ogsa/ogsa-6.1.0.5/ObjectGrid/bin/xsadmin.sh: not found.
Syntax Error The source line is 2.
The error context is
/Total known containers/ >>> { <<<
awk: 0602-502 The statement cannot be correctly parsed. The source line is 2.
awk: 0602-540 There is a missing } character.

I copied and pasted the script exactly as yuo had it for the bourne shell:

#!/bin/sh
export JAVA_HOME=` /hosting/products/WebSphereU01/java/hosting/ogsa/ogsa-6.1.0.5/ObjectGrid/bin/xsadmin.sh -p 26572 -bp 26570 -ch nc3sz2ecmus02 -containers | awk ' {
/Total known containers/ { sum += $NF; next}
/Total known hosts/ { sum += $NF; next; }
END {
printf( "%d\n", sum > 161 && sum < 164 ? 1 : 0 );
}' `
