how to access variable outside awk and spliting the string in array

Expand Post »

Hello I am new to Unix. Please help me out.
My Scenario:
I am first collecting all the file names present in the directory with structure myinfo/yourinfo/supplierinfo
I have four files with the names myCollector.java, yourCollector.java, someCollector.java, everyCollector.java. in the directory.

I am reading the file name and i am getting myinfo/yourinfo/supplierinfo/myCollector.java. and the such string for other files.
I am spliting it to get only substring "myCollector" from the above string which is stored in variable progexe.

How can i access this variable outside awk so that i can run that java class.

#!/bin/bash

pruneclass="$(find myinfo/yourinfo/supplierinfo -name "*llector.java*")"
 
echo "$pruneclass"| awk '{
                                z=split($0,flds," ")
                                for(i=1;i<=z;i++)
                                progcompile=flds[i]
                                p2 = length(progcompile)
                                exetemp=substr(progcompile,41,p2)
                                progexe=substr(exetemp,0,length(exetemp)-5)        [inline] # Please dont worry about the above code [/inline]
                                progexearr[i]=progexe
	              print progexe         [inline]                        # i am getting myCollector, yourCollector,someCollector and everyCollector. How can i access the value of variable and array outside awk.   [/inline]
	              print progexearr[i]               
                           }'

                                for(i=1;i<=z;i++)
                                progcompile=flds[i]
                                p2 = length(progcompile)
                                exetemp=substr(progcompile,41,p2)
                                progexe=substr(exetemp,0,length(exetemp)-5)        [inline] # Please dont worry about the above code [/inline]
                                progexearr[i]=progexe
	              print progexe         [inline]                        # i am getting myCollector, yourCollector,someCollector and everyCollector. How can i access the value of variable and array outside awk.   [/inline]
	              print progexearr[i]               
                           }'

#echo $progexe      [inline] # Not able to get value of progexe or array progexearr here [/inline]
#java -classpath $CLASSPATH:. $progexe

OR i have used another approach which is.....

                            for (( j = 0 ; j <= ${#st[*]} ; j++ ))
                                {

                                }

Any help would be really appreciated. I am trying it for 3 days and not yet successful.
Thanks in advance.

Re: how to access variable outside awk and spliting the string in array

If I understand correctly all you need is just:

Shell Scripting Syntax (Toggle Plain Text)
for prog in /myinfo/yourinfo/supplierinfo/*Collector.java;do
	progname="${prog##*/}"
	java -classpath "$CLASSPATH:." "${progname%.java}"
done
for prog in /myinfo/yourinfo/supplierinfo/*Collector.java;do
	progname="${prog##*/}"
	java -classpath "$CLASSPATH:." "${progname%.java}"
done

Re: how to access variable outside awk and spliting the string in array

sorry sir, its not working

actually while executing the java program we need only program name without .java extension

i.e. java myCollector #No .java as extension

that is the reason that i am trying to split the string either using awk or spliting string in array

but a great thanks radoulov...for taking interest to help me
