我正在尝试编写一个批处理文件来检查文本文件中存在的文件名是否存在于文件夹中。我有一个名为 PAN 的文件夹，其中有一个名为 PRAS_filelist.txt 的文本文件，其中存储了所有文件名。还有一个文件夹 PRAS，我的所有文件都在其中。

我的要求是它应该扫描文件夹，最后，它应该在文件 PRAS_PP_ERROR_LOG 中填充一条错误消息。但是现在如果任何一个文件都不存在，它就会出现，因为我已经使用了退出。

下面是代码

`rm -f ../SessLogs/PRAS_PP_ERROR_LOG`
for i in `cat ./PAN/PRAS_filelist.txt`
do
    file_name=$i
    if [ -e ./PAN/PRAS/"$file_name"_* ]
    then
        if [ -s ./PAN/PRAS/"$file_name"_* ]
        then
            a=`sed -n '1p' ./PAN/PRAS/"$file_name"_*|cut -d'|' -f1`
            b=`sed -n '$p' ./PAN/PRAS/"$file_name"_*|cut -d'|' -f1`
            if [ "$a" == "H" ] && [ "$b" == "T" ]
            then
                trailer_record=`sed -n '$p' ./PAN/PRAS/"$file_name"_*|cut -d'|' -f2`
                record_count=`wc -l ./PAN/PRAS/"$file_name"_*|cut -d' ' -f1`
                r_c=`expr $record_count - 1`
                if [ $trailer_record -eq $r_c ]
                then
                    `cp ./PAN/PRAS/"$file_name"_* ./PAN/PRAS/STANDARDIZE/"$file_name"`
                    `sed -i '$d' ./PAN/PRAS/STANDARDIZE/"$file_name"`
                else 
                    echo "ERROR in file $file_name: Count of records is $r_c and trailer is $trailer_record">../SessLogs/PRAS_PP_ERROR_LOG  
                fi  
            else
                echo "ERROR in file $file_name: header or trailer is missing">../SessLogs/PRAS_PP_ERROR_LOG
                exit 1 
            fi 
        else
            echo "ERROR in file $file_name: empty file">../SessLogs/PRAS_PP_ERROR_LOG
            exit 1
        fi
    else
        echo "ERROR: $file_name doesnot exist">../SessLogs/PRAS_PP_ERROR_LOG
        exit 1
    fi
done

稍微重构你的代码：

一件奇怪的事情是，您声称拥有一个文件名列表，但随后在检查文件是否存在之前附加了一个下划线。实际的文件名是否真的有下划线？

#!/bin/bash
shopt -s nullglob

logfile=../SessLogs/PRAS_PP_ERROR_LOG
rm -f $logfile

while read file_name; do
    files=( ./PAN/PRAS/${file_name}_* )
    if (( ${#files[@]} == 0 )); then
        echo "ERROR: no files named ${file_name}_*"
        continue
    elif (( ${#files[@]} > 1 )); then
        echo "ERROR: multiple files named ${file_name}_*"
        continue
    fi

    f=${files[0]}

    if [[ ! -s $f ]]; then
        echo "ERROR in file $f: empty file"
        continue
    fi

    a=$(sed    '1q' "$f" | cut -d'|' -f1)
    b=$(sed -n '$p' "$f" | cut -d'|' -f1)

    if [[ "$a" != "H" || "$b" != "T" ]]; then
        echo "ERROR in file $f: header or trailer is missing"
        continue
    fi 

    trailer_record=$(sed -n '$p' "$f" | cut -d'|' -f2)
    r_c=$(( $(wc -l < "$f") - 1 ))

    if (( trailer_record == r_c )); then
        sed '$d' "$f" > ./PAN/PRAS/STANDARDIZE/"$file_name"
    else 
        echo "ERROR in file $f: Count of records is $r_c and trailer is $trailer_record"
    fi  

done < ./PAN/PRAS_filelist.txt | tee $logfile
