List the files with latest data

I was trying to get a list of files with latest data in a day. The day can be found from the file name.

Input files of type abc_YYYYMMDDHH24MISS.txt

abc_20230101033006.txt  
abc_20230101043006.txt
abc_20230102033006.txt  
abc_20230102043006.txt

expected output 
abc_20230101043006.txt
abc_20230102043006.txt

I have tried this command

ls | cut -b 1-12|uniq |ls |sort|tail -1

result :(getting only one file)

abc_20230102043006.txt

>Solution :

Using awk:

$ ls -1
abc_20230101033006.txt
abc_20230101043006.txt
abc_20230102033006.txt
abc_20230102043006.txt

$ printf '%s\n' abc_* |
    awk '{k=substr($0, 0,12);a[k]=$0}END{for (i in a) print a[i]}'

abc_20230101043006.txt
abc_20230102043006.txt
