btmps and wtmps files

[Carles Viaplana]

Hello,

wtmps and btmps are too much large. Can we initialize these files?

Thanks in advance for your help.

Hello,

i've recently wrote a script for purging these files, it's here:

---<---
#!/bin/ksh

[ "$(uname -s)" = "HP-UX" ] && {
MAX_SIZE="1024000"
REST_LINES="10000"

for XTMP in /var/adm/wtmp /var/adm/btmp /etc/utmp
do
[ -f "$XTMP" ] || continue
SIZE=
SIZE=$(/bin/ls -l $XTMP |awk '{print $5}' 2>/dev/null)

if [ "$SIZE" -gt "$MAX_SIZE" ]
then
/usr/sbin/acct/fwtmp < ${XTMP} >/tmp/${XTMP##*/}.OLD
tail -n $REST_LINES /tmp/${XTMP##*/}.OLD |/usr/sbin/acct/fwtmp -ic > $XTMP
rm /tmp/${XTMP##*/}.OLD 2>/dev/null
fi
done
}
