我是Korn shell脚本的新手，但我正在学习。我尝试运行一个嵌套FOR循环的WHILE循环来读取CFG文件并删除某些超过设定天数的文件。该脚本运行正常，没有错误，但它似乎没有拾取我在循环中的命令。下面将包括脚本，CFG文件示例和脚本的输出，其中包括set -x。到目前为止，我所尝试的一切都失败了，或者没有收到命令。蒂亚！
CFG文件;

FILE_PATH=/export/home/jaqst/training/testdir_1/ *.txt DAYS=7
FILE_PATH=/export/home/jaqst/training/testdir_1/ *.txt DAYS=14

 cd ${CFGFILE}
 if [[ $? -ne 0 ]]
    then
    echo `date +%d\ %b\ %H:%M` `basename $0` ${USER} "failed to cd into ${CFGFILE}"
    exit 9

             if [ -f $FILE ]; then
                if [ "$(find $FILE -mtime +$DAYS -print)" ]; then
                   rm -f $FILE

从输出中看，它似乎只阅读CFG文件中的第一行。
我已经尝试了WHILE和FOR循环的组合，并开始研究使用AWK命令，看看这是否会允许脚本更容易地读取文件。
我也尝试了下面的方法，但它错误地显示消息-[52] [: argument expected

while read FILE_PATH; do 
   read DAYS
   for FILE in $FILE_PATH/*; do
   for TIME in $DAYS/*; do
   mod_time=$(stat -c %Y $FILE)
   current_time=$(date +%s)
   age=$(( (current_time - mod_time) / (24 * 60) ))
 if [ $age -gt $DAYS ]
    then 
    rm $FILE
 fi
 if [[ $? -ne 0 ]] 
    then
    echo `date +%d\ %b\ %H:%M` `basename $0` ${USER} "failed to remove file"
    exit 9
 fi
 done < hkeep_hera_cfg
