实验的具体输入返回解析器错误

                for repeat in {1..10}; do
                    executiontime=$(timeout 500 gtime -f "%U" /Users/ouafaelachhab/Desktop/SemanticLocality/optimathsat-1.6.2-macos-64-bit/bin/optimathsat < file.smt2 2>&1 >/dev/null)
                    echo "$executiontime"
                    total=$(echo "scale=2; ($total) + ($executiontime)" | bc) #echo $(bc <<< "scale=2; $total/100")
                    echo "$total"
                    let "m=m+1"
                    echo "m=$m"
                done
                echo $(bc <<< "scale=2; ($total)/10") >> results.csv
                ratio=$(echo "scale=10; ($ratio) + ($step)" | bc) #float points arithmetics are different
            done
            short=$(echo "scale=10; ($short) + ($step)" | bc)
            long=$(echo "scale=10; ($long) - ($step)" | bc)
        done
    done

我基本上只是运行一个实验,我运行变量输入的文件。代码适用于某些值,对于某些值,它只是给了我:

(standard_in) 1: parse error

在我的结果文件中,这是我的输出:

50 0 1 0
21.82
50 0 1 .2
27.08
50 0 1 .4
40.89
50 0 1 .6

我正在运行的实验总是停在相同的输入值(输出文件中打印的最后一个),然后从那里得到所有解析器错误!为什么这样做?以及如何解决这个问题?我尝试了多个解决方案,我发现类似的问题(与bc相关),但没有一个工作。

bash macos shell floating-point bc

我怀疑它与以下行有关:


executiontime=$(timeout 500 gtime -f "%U" /Users/ouafaelachhab/Desktop/SemanticLocality/optimathsat-1.6.2-macos-64-bit/bin/optimathsat &1 >/dev/null)

当我改变您的代码

executiontime = “ISSUE”

我得到这个作为输出(请注意我是如何逐行打印的)


m=3
