在bash脚本处理sys.excepthook错误 [英] Addressing sys.excepthook error in bash script

问题描述

我写的是做正是​​我想要它做一个bash脚本，但蹬出以下错误：

I've written a bash script that is doing exactly what I want it to do, but kicking out the following error:

关闭失败的文件对象的析构函数：sys.excepthook丢失丢失sys.stderr来

我完全就如何解决这个问题难住了。下面是脚本：

I'm completely stumped on how to address this. Here is the script:

#!/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)

---------------------------------------
FIRST TEN ROWS OF FIRST FIVE COLUMNS

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

$(csvcut $INPUTFILE | csvstat )

echo "Audited!"

我是pretty新的shell脚本和很新的蟒蛇。我会感谢任何帮助。

I am pretty new to shell scripts and very new to python. I would be grateful for any help.

推荐答案

这是一个Python管道输出时2.6.2脚本到的头，我看到这个错误命令庆典在Ubuntu 9.04。我加了尝试块，收标准输出和标准错误退出前脚本：

I was seeing this error when piping output from a Python 2.6.2 script into the head command in bash on Ubuntu 9.04. I added try blocks to close stdout and stderr before exiting the script:

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

我不再看到的错误。

I am no longer seeing the error.
