Excellent explaination !!!!

Thanks a lot for ur replies, unbeliver

Now shell script have got some good shape in executing those java process.
Next concern is , i want to do preliminary check before executing java process inside the shell script ...
Code:
CLASSPATH=.
CLASSPATH=${CLASSPATH}:sampleswing.jar
nohup java -cp ${CLASSPATH} Sample > /dev/null 2>&1 &
echo "kill -9 "$! > killer.sh
chmod 777 killer.sh


Preliminary check is necessary to make sure that any already spawned java process are killed completely before starting another process with the shell script. For this purpose only , i have stored the process ID of the java process in a file called Killer.sh which contains command
Quote:
kill -9 pid
Basically i want to execute killer.sh as a first command before executing
Quote:
nohup java -cp ${CLASSPATH} Sample > /dev/null 2>&1 &
Suppose for the first time , if there is no killer.sh available , then there should not be any problem when i execute it.

Kindly get me a code that can be included before executing
Quote:
nohup java -cp ${CLASSPATH} Sample > /dev/null 2>&1 &
which kills the already running java process, also it indirectly make sure that only one java process can be run at any time.Code construct also shud handle if that file 'killer.sh' is not available.

Reply wud be very much appreciated

NAME
git-check-attr - Display gitattributes information SYNOPSIS
git check-attr attr... [--] pathname... git check-attr --stdin [-z] attr... < <list-of-paths> DESCRIPTION
For every pathname, this command will list if each attribute is unspecified, set, or unset as a gitattribute on that pathname. OPTIONS
--stdin Read file names from stdin instead of from the command-line. -z Only meaningful with --stdin; 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 not supplied, only the first argument will be treated as an attribute. OUTPUT
The output is of the form: <path> COLON SP <attribute> COLON SP <info> LF <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. EXAMPLES
In the examples, the following .gitattributes file is used: .ft C *.java diff=java -crlf myAttr NoMyAttr.java !myAttr README caveat=unspecified .ft o Listing a single attribute: .ft C $ git check-attr diff org/example/MyClass.java org/example/MyClass.java: diff: java .ft o Listing multiple attributes for a file: .ft C $ 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 .ft o Listing an attribute for multiple files: .ft C $ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java org/example/MyClass.java: myAttr: set org/example/NoMyAttr.java: myAttr: unspecified .ft o Not all values are equally unambiguous: .ft C $ git check-attr caveat README README: caveat: unspecified .ft SEE ALSO
