We have log files dating back to 2004. I need to write an interative script that will request the user for how many months he needs to keep the log files and remove all the remaing log files after that month.
Supposing we are now in June 2006 , if teh user request to keep log file for the last 3 months, the script will need to delete all the files prior to April 2006. i.e files prior to from April 01 2006 .

Pls suggest a solution

Thanks.

The script below will search for files older than $FileAge and compress it. You can change the compress command to delete.

Hope this helps.

#!/bin/ksh
echo "Enter age of file to retain for this compress
echo "1) 1 month 3) 3 months"
echo "2) 2 months 4) Exit"
echo "Please enter your choice : \c"
read choice

case $choice in
1)
echo "compressing all files older than 1 month"
FileAge=30
echo "processing...";;
2)
echo "compressing all files older than 2 months"
FileAge=60
echo "processing...";;
3)
echo "compressing all files older than 3 months"
FileAge=90
echo "processing...";;
4)
echo "You have chosen to exit"
exit;;
*)
echo "Sorry, that's not in the menu.";;
esac

# Compress files that does not end with .Z and .gz from $CompressPath dir
echo "Compressing files from $CurrDir" >&2
for VAR1 in `find "${CompressPath}/." \( ! -name . -a ! -name '*.Z' -a ! -name '*.gz' \) -prune -type f -mountstop -mtime +${FileAge}`
do
# check if an existing compresed name is existing for the target file
if [ -a ${VAR1}.gz ] || [ -a ${VAR1}.Z ]
then
# Append a datestamp to the file
VAR2="${VAR1}.${TimeStamp}"
mv $VAR1 $VAR2

# Proceed to compress this renamed file
#${GZIP} $VAR2
gzip $VAR2
else
#${GZIP} $VAR1
gzip $VAR1
fi
done
