#!/bin/bash
clear
echo "Please Enter YESTERDAYS Date in this order Mmm dd"
echo -n "Enter Date:"
read otaibi
ls -l /pcard17/trace | grep "$otaibi" | grep HSM_VERIF.* | nawk '{print $9}' > /pcard17/trace/delete.txt
clear
cd /pcard17/trace
cat /pcard17/trace/delete.txt | while read line; do rm "$line" ; done

è possibile utilizzare trovare comando per trovare e cancellare i file di ieri

find your/dir/path -type f -name "HSM_VERIF.*" -mtime +1 -exec rm {} \;

sì vorrei tenere più di due file di ieri.

Esempio giorno 2 luglio

ls -alt HSM_VERIF.* | grep " Jul  2 " | sed -n '3,$p' |  xargs rm -f

ls -alt HSM_VERIF.* | grep " Jul  2 " | sed -n '3,$p' | while read line
do
      rm -f "$line"
done

grazie per l'aiuto che funziona come un fascino
