Access value outside awk or split value of array
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
source ~/.login
progexearr=""
pruneclass=""
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) # Please dont worry about the above code
progexearr[i]=progexe
print progexe # i am getting myCollector, yourCollector,someCollector and everyCollector. How can i access the value of variable and array outside awk.
print progexearr[i]
}'

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


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


#!/bin/bash
source ~/.login
pruneclass=""
pruneclass="$(find myinfo/yourinfo/supplierinfo -name "*llector.java*")"
st=(echo "$pruneclass")
for (( j = 0 ; j <= ${#st[*]} ; j++ ))
{
#echo ${st[*]}
echo "${st[$j]}"
#echo ${st[j]}

javac ${st[$j]} # Here the string is myinfo/yourinfo/everyinfo/myCollector.java which is compiling absolutely fine
#java -classpath $CLASSPATH:. ${st[$j]}
# But here i want only substring "myCollector" in order to execute it. How do i split the string values of array to get the substring "myCollector".
}

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

git-check-attr

GIT-CHECK-ATTR(1)						    Git Manual							 GIT-CHECK-ATTR(1)

NAME

       git-check-attr - Display gitattributes information

SYNOPSIS

       git check-attr [-a | --all | attr...] [--] pathname...
       git check-attr --stdin [-z] [-a | --all | attr...]

DESCRIPTION

       For every pathname, this command will list if each attribute is unspecified, set, or unset as a gitattribute on that pathname.

OPTIONS

       -a, --all
	   List all attributes that are associated with the specified paths. If this option is used, then unspecified attributes will not be
	   included in the output.

       --cached
	   Consider .gitattributes in the index only, ignoring the working tree.

       --stdin
	   Read pathnames from the standard input, one per line, instead of from the command-line.

       -z
	   The output format is modified to be machine-parseable. If --stdin is also given, input paths are separated with a NUL character instead
	   of a linefeed character.

       --
	   Interpret all preceding arguments as attributes and all following arguments as path names.

       If none of --stdin, --all, or -- is used, the first argument will be treated as an attribute and the rest of the arguments as pathnames.

OUTPUT

       The output is of the form: <path> COLON SP <attribute> COLON SP <info> LF

       unless -z is in effect, in which case NUL is used as delimiter: <path> NUL <attribute> NUL <info> NUL

       <path> is the path of a file being queried, <attribute> is an attribute being queried and <info> can be either:

       unspecified
	   when the attribute is not defined for the path.

       unset
	   when the attribute is defined as false.

       set
	   when the attribute is defined as true.

       <value>
	   when a value has been assigned to the attribute.

       Buffering happens as documented under the GIT_FLUSH option in git(1). The caller is responsible for avoiding deadlocks caused by
       overfilling an input buffer or reading from an empty output buffer.

EXAMPLES

       In the examples, the following .gitattributes file is used:

	   *.java diff=java -crlf myAttr
	   NoMyAttr.java !myAttr
	   README caveat=unspecified

       o   Listing a single attribute:

	   $ git check-attr diff org/example/MyClass.java
	   org/example/MyClass.java: diff: java

       o   Listing multiple attributes for a file:

	   $ git check-attr crlf diff myAttr -- org/example/MyClass.java
	   org/example/MyClass.java: crlf: unset
	   org/example/MyClass.java: diff: java
	   org/example/MyClass.java: myAttr: set

       o   Listing all attributes for a file:

	   $ git check-attr --all -- org/example/MyClass.java
	   org/example/MyClass.java: diff: java
	   org/example/MyClass.java: myAttr: set

       o   Listing an attribute for multiple files:

	   $ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java
	   org/example/MyClass.java: myAttr: set
	   org/example/NoMyAttr.java: myAttr: unspecified

       o   Not all values are equally unambiguous:

	   $ git check-attr caveat README
	   README: caveat: unspecified
