Bash Version: 3.0
Patch Level: 16
Release Status: release

Description:
        
Problem 1:
--------
Following is the code (in a shell script)which redirects find command
output to a file called "src". But this command generates a file called
"src?" instead.

SOURCE_PATH="src"
rm -f $SOURCE_PATH
#Getting all OPS src files
find ../../com/onmobile/noc/common -name *.java > src

Problem 2:
---------
Later I need to read the src file.
To circumvent Problem 1, if I use the below code :

SOURCE="$SOURCE_PATH?"
$JAVA_HOME/bin/javac -classpath $CLASSPATH -d $OUTPUT_PATH -sourcepath <
cat $SOURCE

I receive following error:
cat: No such file or directory

Could this problem be solved?

I'm facing this problem even in CentOS 10.0
Bash Version: GNU bash, version 3.1.17(1)-release
(i686-redhat-linux-gnu)

Fix:

Thanks,
