Question

我有两个几乎相同的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：

这个很好用：

#!/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 ""

但是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。运行第二个脚本会产生以下结果：

“......”还有很多行，但它们基本上只是同一个想法的变体。

Answer 1

错误消息由bc生成。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Vertical目录的内容。您的某个CSV文件名称中是否包含空格或奇数字符？尝试使用引号括起文件名的变量：

"\"${filename}\""

Answer 3

（standard_in）1：语法错误

使用 perl 代替bc命令

可以解决此错误

$（perl -e“print $ b + $ c”）

bash脚本中的Standard_in错误
