bash腳本中的Standard_in錯誤

Question

我有兩個幾乎完全相同的bash腳本。一個人工作，一個人不工作，我不知道發生了什麼。下面是腳本：

這一個正常工作：

#!/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 "" 

但是這樣一來給了我各種錯誤：

#!/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 "" 

這兩個文件是相同的，除了目錄（土方VS立式）和節目名稱（earthmove vs vertical）。我知道這是因爲我通過複製和粘貼第一個來創建第二個。運行第二個腳本的結果是：

有很多更多的線路，其中「...」是的，但他們基本上只是在同樣的想法的變化。

Answer 1

檢查垂直目錄的內容。其中一個CSV文件的名稱中是否有空格或奇數字符？嘗試圍繞保持在報價文件名變量：

"\"${filename}\"" 

Answer 2

的錯誤消息是由bc生產。問題是在文件「$ HOME/Documents/Development/road/Vertical/utest/$ file.res」中沒有包含「S：S：N：I :: O：P ...」之類的東西在另一個腳本中使用的相應文件。很有可能你期望這個文件包含一個單一的數值，而不是現在的文件。

Answer 3

（standard_in）1：語法錯誤

該錯誤將通過使用的perl代替bc命令來解決，

$（perl的-e「打印$ B + $ C 「）
