我编写了一个bash脚本，该脚本确实可以执行我想要的操作，但是会出现以下错误：

close failed in file object destructor: sys.excepthook is missing lost sys.stderr

我完全不知道如何解决这个问题。这是脚本：

#!/bin/bash

usage () { echo "${0##*/} inputfile outputfile"; exit 1; }

(($#==2)) || usage

INPUTFILE="$1"
OUTPUTFILE="$2"

#  All that is written between between the 'cat' command and 
#+ 'EOF' will be sent to the output file.
cat <<EOF >$OUTPUTFILE
$(date "+Generated on %m/%d/%y at %H:%M:%S")

DATA AUDIT: $1

$(csvcut -n $INPUTFILE)

$(csvcut -c 1,2,3,4,5 $INPUTFILE | head -n 10)

$(csvcut $INPUTFILE | csvstat )

echo "Audited!"

我对shell脚本很陌生，对python也很陌生。我将不胜感激。
