You want to use a here document.  Ie,

myapp << SOME_SYMBOL
1
2
$A_Variable        
SOME_SYNBOL
echo "Script can resume here"

You need a here script

#!/bin/sh

postm=postmaster

telnet mailhost 25 << EOF
vrfy $postm
quit
EOF
# This program reads the lines between the command and the line EOF as if
# they were standard input

1. PLEASE PLEASE HELP Major problem with my SCSI & Redhat 5.0 PLEASE Help

Everything ran WONDERFUL for about 4 months this machine ran several
servers it is a UDB w/ 340mb SCSI (SLOW 5mb) half inch internal hard
drive.  32 megs of true parity ram, Red hat 5.0 I get the following
error

NCR53-810-0: ERROR (0:48) (0-20-0) (8/33) * scripth (868:18000400).
NCR53-810-0: Script cmd = 888030000
NCR53-810-0: regdump : da 10 80 33 47 08 00 1f 01 08 00 28 80 00 08 00
NCR53-810-0: have to clear fifos

What the HELL is this and is there anyway to fix it ?  It seems to
occur when doing file writing, when i try to tar something for example
it will go into a continual unending loop displaying the above error
message.  I have refdisked, formated, and clean installed redhat and
the problem is still there :( Please help, if at all possible mail
