FS refresh script

[gringomike]

Hi folks!

I'm trying to script the refresh of a file system and have compiled the code below. This works fine but for the fact I have to hit the <enter> key once it gets to the /usr/sbin/vxassist -g rootdg make test_fs 1g disk01 line where the script just hangs until the user intervenes:-(

Does anybody know why this is and how I can get around it?

Cheers!

GM

rsh jupiter /usr/sbin/ufsdump 0uf venus:/apps/JUPITER_apps/JUPITER_test /usr/bin/nsr
echo &quot;dump of /usr/bin/nsr complete&quot;

echo &quot;unmounting /test_fs.....&quot;
/usr/sbin/umount -f /test_fs
echo &quot;/test_fs unmounted successfully&quot;

echo &quot;re-creating /test_fs file system.....&quot;

/usr/sbin/vxassist -g rootdg make test_fs 1g disk01

/usr/sbin/mount -o rw /dev/vx/dsk/rootdg/test_fs /test_fs
echo &quot;/test_fs file system re-created&quot;

echo &quot;restoring the /test_fs file system&quot;
cp /apps/JUPITER_apps/JUPITER_test /test_fs
cd /test_fs
/usr/sbin/ufsrestore rf JUPITER_test
/usr/sbin/umount -f /test_fs
/usr/sbin/mount -o ro /dev/vx/dsk/rootdg/test_fs /test_fs
echo &quot;/test_fs file system restored as read only&quot;

Do this pipe really work??

/usr/sbin/newfs /dev/vx/rdsk/rootdg/test_fs |read $ANS

Unless vxassist reads /dev/tty instead of stdin, you can try this:

echo "" | /usr/sbin/vxassist -g rootdg make test_fs 1g disk01

Hope This Help

How would you guys tackle this problem? I don't think I'm far off a working solution but if I can't get this working I might have to abandon it and start from the begining again:-(

/usr/sbin/vxassist -g rootdg make test_fs 1g disk01 <<eof

eof

Syntax of above is

command <<eof
<enter>
eof

or you could look at expect

Thanks for your replies everybody!

I was running the script using /bin/ksh and by changing it to be run by /sbin/sh it completes without a problem.
Expect would have been the next method I would have looked at!

Thanks again!
