bash脚本中的Standard_in错误

Question

我有两个几乎完全相同的bash脚本.一个工作,一个不工作,我无法弄清楚发生了什么.以下是脚本:

这个工作正常:

#!/bin/bash

CURDIR=$HOME/Documents/Development/road/Earthmoving
TOL=0.05

echo -e "\nRunning Unit Tests"
echo -e "------------------\n"

for infile in $CURDIR/utest/*.csv
do
    file=$(basename $infile .csv)
    echo -n " Test $file"
    value=`$CURDIR/Release/earthmove -f $infile`
    res=`cat $CURDIR/utest/$file.res`
    if [ "$(echo "$res+$TOL*$res >= $value && $res-$TOL*$res <= $value" | bc)" -eq 1 ]; then
    echo -e "\t\t PASSED."
    else
    echo -e "\t\t FAILED."
    fi;
done

echo ""

但这个给了我各种错误:

#!/bin/bash

CURDIR=$HOME/Documents/Development/road/Vertical
TOL=0.05

echo -e "\nRunning Unit Tests"
echo -e "------------------\n"

for infile in $CURDIR/utest/*.csv
do
    file=$(basename $infile .csv)
    echo -n " Test $file"
    value=`$CURDIR/Release/vertical -f $infile`
    res=`cat $CURDIR/utest/$file.res`
    if [ "$(echo "$res+$TOL*$res >= $value && $res-$TOL*$res <= $value" | bc)" -eq 1 ]; then
    echo -e "\t\t PASSED."
    else
    echo -e "\t\t FAILED."
    fi;
done

echo ""

除了目录(Earthmoving vs Vertical)和程序名称(earthmove vs vertical)之外,这两个文件是IDENTICAL.我知道这是因为我通过复制和粘贴第一个来创建第二个.运行第二个脚本会导致:

"......"有更多的线条,但它们基本上只是同一个想法的变体.

Answer 1

错误消息由bc.产生.问题是在"$ HOME/Documents/Development/road/Vertical/utest/$ file.res"文件中有"S:S:N:I :: O:P ..."之类的内容在另一个脚本中使用的相应文件.您可能希望该文件包含单个数值而不是现在的任何数值.

Answer 2

检查垂直目录的内容。您的 CSV 文件之一的名称中是否包含空格或奇怪字符？尝试将包含文件名的变量括在引号中：

"\"${filename}\""
