After enable debug for IPC::Run, I found the following logs: IPC::Run 0001 0123456789012-4 [#2(415745)]: writing to fd 11 (kid's stdin) IPC::Run 0001 0123456789012-4 [#2(415745)]: write( 11, 'SEL ' ) = 4 <- Here write 4 bytes.

It seems the 'SEL\t' is converted to 'SEL ' which is "SEL" with 5 spaces. -- Regrads, Japin Li ChengDu WenWu Information Technology Co., Ltd.
