Bug Get first column from a huge string ..!!
Guys

Look at the following string....!!


Code:
/global/site/vendor/Vignette7/Content/7_5/java5/jre/bin/java -classpath /global/site/vendor/Vignette7/Content/7_5/lib/vgnconfiglauncher.jar -Dcom.vignette.jvmid=V7CDS1CA1 -DVgnStartupClass=com.vignette.config.agent.Agent -DVgnClassPathFile=/global/site/vendor/Vignette7/Content/7_5/V7CDS1CA1/conf/cfa.classpath -Xms32m -Xmx128m -Dcom.vignette.workingDir=/global/site/vendor/Vignette7/Content/7_5/V7CDS1CA1 -Dcom.vignette.installDir=/global/site/vendor/Vignette7/Content/7_5 -Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl -Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl -Dorg.apache.commons.logging.Log=com.vignette.logging.CommonsLogger com.vignette.config.launcher.vgnlauncher -c /global/site/vendor/Vignette7/Content/7_5/V7CDS1CA1/conf/cfa.cfg -i /cs/config.cfa-V7CDS1CA1



From this huge string ,i just need
Code:
global/site/vendor/Vignette7/Content/7_5/java5/jre/bin/java

1.awk '{print $1}'
2.nawk '{print $1}'
3.nawk -F ' ' '{print $1}'

Hi.

The first awk works fine. What error do you get (and what OS are you using)?

I am getting a time out error.

I am trying to do following on Solaris 5.10

Code:
CMD=<first huge string i pasted>
A=$(echo $CMD |nawk -F ' ' '{print $1}')

B=`dirname $A`

if [ $B = "." ]
then
echo ""
else
echo $B
fi

Hmm.

In Solaris 10, it works with nawk

Code:
# cat Test
CMD="/global/site/vendor/Vignette7/Content/7_5/java5/jre/bin/java -classpath /global/site/vendor/Vignette7/Content/7_5/lib/vgnconfiglauncher.jar -Dcom.vignette.jvmid=V7CDS1CA1 -DVgnStartupClass=com.vignette.config.agent.Agent -DVgnClassPathFile=/global/site/vendor/Vignette7/Content/7_5/V7CDS1CA1/conf/cfa.classpath -Xms32m -Xmx128m -Dcom.vignette.workingDir=/global/site/vendor/Vignette7/Content/7_5/V7CDS1CA1 -Dcom.vignette.installDir=/global/site/vendor/Vignette7/Content/7_5 -Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl -Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl -Dorg.apache.commons.logging.Log=com.vignette.logging.CommonsLogger com.vignette.config.launcher.vgnlauncher -c /global/site/vendor/Vignette7/Content/7_5/V7CDS1CA1/conf/cfa.cfg -i /cs/config.cfa-V7CDS1CA1"

A=$(echo $CMD | nawk '{print $1}')

B=`dirname $A`

if [ $B = "." ]
then
echo ""
else
echo $B
fi
# ./Test
/global/site/vendor/Vignette7/Content/7_5/java5/jre/bin

Is that the actual string you used? How long until this "time out"? Can you run the script, and post the output, including the error?

Tools Put in an intermediate marker
After setting A, do an
Code:
echo $A

just to make sure that line is where the 'time-out' is occurring.

It would help isolate the problem because in theory anyway, that second command could be the culprit.

I have written code like this:

Code:
A=$(/usr/ucb/ps -alxww | nawk '$2 != "UID" { printf("%s %s ",$1,$2);system("getent passwd "$2"| sed s/:.*$// | tr -d \\\\n");$1=""; $2=""; print $0 }$2 == "UID" { $2="UID USER"; print }'|nawk -F' ' '{ if($4 == "29040"){substr("^    ","");print}}')

B=$(echo "$A" |nawk '{print substr($0,index($0,":")+3,length($0))}'|nawk -F ' ' '{print $1}')

C=$(dirname "$B")

if [ $C = "." ]
then
echo ""
else
echo $C
fi

no error...my engine simply got exhausted ...i am not sure if its bcoz of string size or i have written something wrong above [though it works fine now for the earlier huge string i had pasted ]


give me something which will give me first column ,irrespective of the string length,size etc....

help me out guys !!
