While perusing a BSDI system I used to administrate, I found the
following code in /etc/monthly and /etc/daily that seemed to make a lot
more sense that some of the stuff I saw in our equivilant files:
rotate() {
file="$1"; shift
rm -f "$file.$1" "$file.$1.gz"
for i in "$@"; do
[ "$i" = "0" ] && j="" || j=".`expr $i - 1`"
[ -f "$file$j.gz" ] && mv -f "$file$j.gz" "$file.$i.gz"
[ -f "$file$j" ] && mv -f "$file$j" "$file.$i"
[ "$i" = "0" -a -x $file.scan ] && $file.scan "$file.$i"
[ -f "$file.$i" ] && [ "X$ziplog" = "XYES" ] && /usr/bin/gzip "$file.$i"
done
cp /dev/null "$file"; chmod 644 "$file"
}
Calling is done as follows:
rotate /var/log/maillog 6 5 4 3 2 1 0
rotate /var/log/wtmp 6 5 4 3 2 1 0
rotate /var/log/popper 4 3 2 1 0
Etc. It seems a lot more modular and configurable, etc. It certainly
makes the script files seem more readable -- maybe we should consider
adopting a similar rotate call?
