#!/usr/bin/ksh

print ""
print "Dialog to change a NODE password."
print ""
print "Please enter a node name, or partial node name.  I'll do a lookup on it 
for you!"
read Inode
print ""
print "You entered $Inode , performing lookukp . . . "
/tsmdata/tsm_scripts/q_node.ksh $Inode
print ""
print "There, it should be one of the above. "
print "Please enter the FULL NODE NAME from above."
Inode=""
read Inode
print ""
print "The node we are going to change is $Inode"
print ""
print "Please enter the TSM instance of the node."
read Itsm
print ""
print "The node is in  $Itsm"
print ""
print "Please enter the new password."
read Ipwd
print ""
print "TODO: chg pwd for  node= $Inode  tsm= $Itsm  newpwd= $Ipwd"
print "type \"ok\" to proceed"
read Iok
if [[ $Iok == 'ok' ]]; then
    print ""
    print "performing change . . . "
    /tsmdata/tsm_scripts/run_cmd.ksh $Itsm "update node $Inode $Ipwd"
