newfs

[Donald C Nelson]

Does anyone know how I would take a file like
/dev/vg02/data
/dev/vg02/data2
/dev/vg02/data3
/dev/ora/lvol1

and extract it so I could replace the logical volume with the r before the logical volume so I could use this for an input to a newfs command no matter what the volume group name is.

Something like this should work:

INFILE=/xxx/yyy/myfile # your above file

cat ${INFILE} | while read X
do
DIR=$(dirname ${X})
LVOL=$(basename ${X})
RLVOL="${DIR}/r${LVOL}"
echo "Full raw volume = ${RLVOL}"
done

man dirname, basename for details.

Hi Donald,

Something like the following will be more simpler. I have tested the output of the following and its working.

#!/usr/bin/sh

vgdisplay -v /dev/vg00|grep -i "lv name" | awk '{print $3}'|cut -f 4 -d "/">test

sed 's/^/r/g' test>rlvols

#here comes your code for newfs
<
code
>

rm test
rm rlvols

#End
