如何删除 bash 脚本中多次出现的变量？

Question

I have the below files in a particular path, and I trying to take the start time and end time from the file name using the cut command in bash script. Since there are three files in it, it is returning the start date and end dates thrice. Due to which the , if condition followed by it, is not getting satisfied.

The input files are:
indonesia_abc_20210517_20210523.csv
indonesia_hair_20210517_20210523.csv
indonesia_bst_20210517_20210523.csv

PFB the code snippet:

if [ $market  == 'indonesia' ]; then
        file_start_dt=`ls -1 ${parent_dirpath}/temp/${market} | cut -d"_" -f3`
        file_end_dt=`ls -1 ${parent_dirpath}/temp/${market} | cut -d"_" -f4 | cut -d"." -f1`
        echo "file start date, $file_start_dt"
        echo "file_end_date,$file_end_dt"
else 
   echo " not working"
   if [ ${file_start_dt} -eq ${start_date} ] && [ ${file_end_dt} -eq ${end_date} ];
       then
           echo "File uploaded to hdfs path successfully for market : $market"

In the log i observe this - '[' 20210517 20210517 20210517 -eq 20210517 ']'
