help me in Shell Scripting

Hi there
please have a look at the code..i want to create Using a named pipe. Run a find in the background starting in the working directory
While this is happening wait for input from the user to ask him which file to find.
If the user does not enter any data in 10 seconds ask the user again.
Then see if the requested file name is found from the output of the find.
If more than one file is found number them 1 to n.

Code:
#!/bin/ksh
echo "Enter your process: "
read answer

FIND=`ps -elf | grep $answer | grep -v grep`
if [ $? -eq 0 ]; then
        echo "process found"
        FINDPROC=`echo "${FIND}"`
        echo "$FINDPROC" | grep -i $answer > MeFile
        count=`cat MeFile | wc -l`
        printf "%s\n" "$count"
        while [[ $count -gt 1 ]]; do
                number=1
                printf "%s\n" "$FINDPROC" | grep -i $answer
                cat -n MeFile > result
                printf "%s\n" | grep result
                exit 0
        done
else
        echo "process not found"
        read answer
fi

What you want is called ksh coprocesses. You have a background job reading and writing to a pipe, and a foreground process to interact withthe user and ask the background to do things asynchronously.
