when I use sed like this :

sed -i  -e 's/\(public class TInfo .*\)$/\1\
\
  private static final long serialVersionUID = -4659975753252858243l; \/\/ See ACCUMULO-3132\
/' src/main/java/org/apache/accumulo/trace/thrift/TInfo.java

It will create a file name TInfo.java-e as a backup,but the -e is not the backup extension I use.

If I use it like this:
sed -i ''  -e 's/\(public class TInfo .*\)$/\1\
\
  private static final long serialVersionUID = -4659975753252858243l; \/\/ See ACCUMULO-3132\
/' src/main/java/org/apache/accumulo/trace/thrift/TInfo.java

It will be work ok and not create a backup file what I want.
