I corrected a small error in the script and allowed for setting TopDir
with an optional second argument
------------------------------------
function BackupPC_zcatPool ()
{
local BACKUPPC_ZCAT=$(which BackupPC_zcat)
local TOPDIR=/var/lib/backuppc
[ -n "$2" -a -d "$2" ] && TOPDIR=$2
local CPOOL="$TOPDIR/cpool"
local POOL="$TOPDIR/pool"
[ -n "$BACKUPPC_ZCAT" ] ||
BACKUPPC_ZCAT=/usr/share/backuppc/bin/BackupPC_zcat
local file=${1##*/} #Strip the path prefix
#If attrib file...
file=${file/attrib[0-9a-f][0-9a-f]_/attrib_} #Convert inode format attrib
to normal attrib
file=${file##attrib_} #Extract the md5sum from the attrib file name
local ABCD=$(printf '%04x' "$(( 0x${file:0:4} & 0xfefe ))")
local prefix="${ABCD:0:2}/${ABCD:2:2}"
# echo $prefix
if [ -e "$CPOOL/$prefix/$file" ]; then #V4 - cpool
$BACKUPPC_ZCAT $CPOOL/$prefix/$file
elif [ -e "$POOL/$prefix/$file" ]; then #V4 - pool
cat $CPOOL/$prefix/$file
elif [ -e "$CPOOL/${file:0:1}/${file:1:1}/${file:2:1}/$file" ]; then #V3 -
cpool
$BACKUPPC_ZCAT "$CPOOL/${file:0:1}/${file:1:1}/${file:2:1}/$file"
elif [ -e "$POOL/${file:0:1}/${file:1:1}/${file:2:1}/$file" ]; then #V3 -
pool
cat "$POOL/${file:0:1}/${file:1:1}/${file:2:1}/$file"
else
echo "Can't find pool file: $file" >/dev/stderr
fi
}
