解决bash脚本中的sys.excepthook错误

Question

我编写了一个正在执行我想要它的bash脚本,但是却出现了以下错误:

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")

我是shell脚本的新手,也是python的新手.我将不胜感激任何帮助.

将Python 2.6.2脚本的输出管道输入到Ubuntu 9.04上的head命令时,我看到了这个错误bash.我加了try块关闭stdout并stderr退出脚本之前:

try:
    sys.stdout.close()
except:
    pass
try:
    sys.stderr.close()
except:
    pass

我不再看到错误.
