Standard_in error in bash script
提问by Jessica
I have two bash scripts that are almost identical. One works and one doesn't and I can't figure out what's going on. Here are the scripts:
我有两个几乎相同的 bash 脚本。一个有效，一个无效，我无法弄清楚发生了什么。以下是脚本：
This one works fine:
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 <= $value" | bc)" -eq 1 ]; then
echo -e "\t\t PASSED."
else
echo -e "\t\t FAILED."
fi;
done
echo ""
But this one gives me all kinds of errors:
但是这个给了我各种各样的错误：
#!/bin/bash
CURDIR=$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 ""
The two files are IDENTICAL besides the directory (Earthmoving vs Vertical) and the program name (earthmove vs vertical). I know this because I created the second by copying and pasting the first. Running the second script results in this:
除了目录（Earthmoving vs Vertical）和程序名称（earthmove vs Vertical）之外，这两个文件是相同的。我知道这一点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：

There are plenty more lines where the "..." is, but they're basically just a variation on the same idea.
“...”所在的行还有很多，但它们基本上只是同一想法的变体。
回答by Paused until further notice.
The error messages are produced by bc. The problem is that there is something like "S:S:N:I::O:P..." in the file "$HOME/Documents/Development/road/Vertical/utest/$file.res" that's not in the corresponding file that's used in the other script. Chances are that you expect that file to contain a single numeric value instead of whatever is in there now.
错误消息由 产生bc。问题是文件“$HOME/Documents/Development/road/Vertical/utest/$file.res”中有类似“S:S:N:I::O:P...”的东西不在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，而不是现在包含的任何数值。

(standard_in) 1: syntax error
(standard_in) 1: 语法错误
This error will be solved by using perlinstead of bc command,
这个错误将通过使用perl而不是 bc 命令来解决，
$(perl -e "print $b+$c")
$(perl -e "打印 $b+$c")

Check the contents of the Vertical directory. Does one of your CSV files have spaces or odd characters in its name? Try surrounding the variable that holds a file name in quotes:
检查 Vertical 目录的内容。您的 CSV 文件之一的名称中是否包含空格或奇数字符？尝试将包含文件名的变量括在引号中：
"\"${filename}\""
