Am facut aseara un script mic care citeste tabelele de partitii
<code>
#!/bin/bash
#This script saves the partition table
#parameter 1 (the only) is the device (/dev/hda)
BS=512
BC=1
if test -z $1;
then
HDD=/dev/hda
HDNAME="`echo $HDD | tr -d '/' `part"
fi
TEMPFILE=`tempfile`
trap "rm $TEMPFILE"
cfdisk -Pr $HDD | grep "Sector " | cut -d ' ' -f2 | cut -d':' -f1 >$TEMPFILE
NOOFPARTS=`cat $TEMPFILE | wc -l`
CPART=`expr $NOOFPARTS + 1`
#echo aici
echo Saving $NOOFPARTS partition tables...
TIMESTAMP="`date -I | tr -d '-'``date | cut -d ' ' -f4 | tr -d ':'`"
echo Timestamp is $TIMESTAMP
echo
while test $CPART -gt 1; do
CPART=`expr $CPART - 1`
SECTNO=`cat $TEMPFILE | tail -n$CPART | head -n1 `
TABLENO=`expr $NOOFPARTS - $CPART`
# echo tableno=$TABLENO
FILENAME="$HDNAME$TABLENO$TIMESTAMP"
#trebuie scos
# touch $FILENAME
# echo cev >>$FILENAME
#dupa finalizare
echo "Saving table $TABLENO to file $FILENAME"
echo "Start sector is $SECTNO"
dd bs=$BS count=$BC skip=$SECTNO if=$HDD of=$FILENAME
echo
done
DIRNAME=$HDNAME$TIMESTAMP
mkdir $DIRNAME
cp $TEMPFILE $DIRNAME/$HDNAME.$TIMESTAMP
rm $TEMPFILE
mv `ls | grep -e "$HDNAME[0-9]$TIMESTAMP"` $DIRNAME
tar cfz $DIRNAME.tar.gz $DIRNAME/*
echo $DIRNAME.tar.gz was be created
rm -rf $DIRNAME
