Report a missing property and property value mis match script.
Hi All,

I have 2 properties files - one is a master templete and other one is a node specific properties file, I need to comapre these 2 properties files and make sure the node Specific properties file contains all the properties in the master temple properties file else report the missing property
and secondly
if value provided in the master template then same value must be in the node specific file if not report mismatch

here are the 2 example property files :

1. master-templete.properties
## Proxy name
jboss.proxy.name=
## PTMS Database
db.host.1=
db.port.1=1521
db.host.2=
db.port.2=1521
#EOF

2.nodeOne.properties
## Proxy name

## PTMS Database
db.host.1=10.3.61.55
db.port.1=1521
db.host.2=10.3.61.55
db.port.2=1521

#EOF

Code:
awk -v MASTER="/path/to/master.file" -v FS="=" 'BEGIN {
        while(getline <MASTER)
        {
                if ( ($0 ~ /^[ \t]*#/) || ($0 == "") ) continue;

                if($2 != "")
                        SET[$1]=$2
        }
}

{
        if (!($0 ~ /^[ \t]*#/) && !($0 == "") )
        if(SET[$1] && (SET[$1] != $2))
                print "ERROR " $0;
}' < /path/to/local.file

Improved version:
Code:
awk -v FS="=" -v MASTER="/path/to/master" 'BEGIN { while(getline <MASTER)
        {
                if (($0 ~ /^[ \t]*#/) || ($0 == "")) continue;
                INMASTER[$1]=1;         VAL[$1]=$2;
        }
}

{       if (!($0 ~ /^[ \t]*#/) && !($0 == "") ) LOCAL[$1]=$2;   }

END {   for(k in INMASTER)
        {
                if((VAL[k] == "") && (LOCAL[k] == ""))  print "UNSET " k;
                if((VAL[k]!="") && (LOCAL[k] != VAL[k])) print "OVERRIDDE " k;
        }
}' < /path/to/local

With your input data, and db.port.2=1521 modified to 1522, I get:

Code:
UNSET jboss.proxy.name
OVERRIDDE db.port.2

When I try to run the script below :
I keep getting the following error , I am not sure what I am doing wrong ..
Please help ...

awk: syntax error near line 1
awk: bailing out near line 1

Note : My properties file "master-templete.properties " and "nodeOne.properties" are in teh same directory as the script.

awk -v FS="=" -v MASTER="master-templete.properties" 'BEGIN { while(getline <"MA
STER")
{
if (($0 ~ /^[ \t]*#/) || ($0 == "")) continue;
INMASTER[$1]=1; VAL[$1]=$2;
}
}
{ if (!($0 ~ /^[ \t]*#/) && !($0 == "") ) LOCAL[$1]=$2; }
END { for(k in INMASTER)
{
if((VAL[k] == "") && (LOCAL[k] == "")) print "UNSET " k;
if((VAL[k]!="") && (LOCAL[k] != VAL[k])) print "OVERRIDDE " k;
}
}' < nodeOne.properties

Use gawk/nawk.

That "MASTER" should be just MASTER -- you aren't trying to read from a file named "MASTER" after all, but a variable named MASTER with a filename in it.

Thank you .
Now nawk works , it doesn't do anything just hangs now.

Hmm. This should print info as it goes, hopefully telling you where it freezes:

Code:
nawk -v FS="=" -v MASTER="/path/to/master" 'BEGIN { 
print "running BEGIN";
while(getline <MASTER)
        {
                if (($0 ~ /^[ \t]*#/) || ($0 == "")) continue;
                INMASTER[$1]=1;         VAL[$1]=$2;
                print $0;
        }
        print "BEGIN finished"
}

{       if (!($0 ~ /^[ \t]*#/) && !($0 == "") ) LOCAL[$1]=$2;   } 1

END {   for(k in INMASTER)
        {
                if((VAL[k] == "") && (LOCAL[k] == ""))  print "UNSET " k;
                if((VAL[k]!="") && (LOCAL[k] != VAL[k])) print "OVERRIDDE " k;
        }
}' < /path/to/local
