Standard_in error in bash script

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:

This one works fine:

#!/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 $in开发者_StackOverflowfile .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:

#!/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:

There are plenty more lines where the "..." is, but they're basically just a variation on the same idea.

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.

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:

"\"${filename}\""

(standard_in) 1: syntax error

This error will be solved by using perl instead of bc command,

$(perl -e "print $b+$c")
