root@cms-db # pwd
/pcard17/trace
root@cms-db # ls -l HSM_VERIF.TRC*

det jeg prøver å gjøre er crating et skript som vil slette bare går filer, og beholder bare siste 2 filer av sikkerhetsmessige grunner.
mitt forsøk på å skape var sånn for å slette alle igår fil
Code:
#!/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
nå Hvordan kan jeg slette igår filer og holde nyeste 2 filer?
