If you can afford working via the file data  you can do  find -mmin  14400 -delete

find is the common tool for this kind of task    find   my dir -mtime  10 -type f -delete   EXPLANATIONS     my dir your directory  replace with your own  -mtime  10 older than 10 days -type f only files -delete no surprise  Remove it to test your find filter before executing the whole command   And take care that   my dir exists to avoid bad surprises

Just spicing up the shell script above to delete older files but with logging and calculation of elapsed time     bin bash  path   data backuplog   timestamp   date   Y m d  H M S      filename log  timestamp txt     log  path filename days 7  START TIME   date   s   find  path -maxdepth 1 -name    txt   -type f -mtime   days  -print -delete  gt  gt   log  echo  Backup   Script Start --   date   Y m d  H M    gt  gt   log       code for backup    or any other operation       gt  gt   log   END TIME   date   s   ELAPSED TIME      END TIME -  START TIME      echo  Backup    Script End --   date   Y m d  H M    gt  gt   log echo  Elapsed Time       date -d 00 00  ELAPSED TIME   Hh  Mm  Ss      gt  gt   log   The code  adds a few  things    log files named with a timestamp log folder specified find looks for   txt files only in the log folder type f ensures you only deletes files maxdepth 1 ensures you dont enter subfolders  log files older than 7 days are deleted   assuming this is for a backup log  notes the start   end time calculates the elapsed time for the backup operation      Note  to test the code  just use -print instead of  -print  -delete  But do check your path carefully though   Note  Do ensure your server time is set correctly via date - setup timezone ntp correctly   Additionally check file times with  stat filename   Note  mtime can be replaced with mmin for better control as mtime  discards all fractions  older than 2 days   2 days  actually means 3 days   when it deals with getting the timestamps of files in the context of days  -mtime   days  --- gt   -mmin      60 24  days
