ksh script with Interactive ssh on remote server
HI Unix Gurus,

I an stuck in an interesting issue, where I am trying to execute a script on remote server after ssh.
The script on remote server is interactive,. Whenever it is called it hangs where it expects input from terminal and I have to terminate it.

I have searched through fourm and found -t -t is one option to use, but its not working in script, though it works from the shell prompt for execution of single command.

Can any one help me with this please.

Below are the brief contents of the KSH Script.

Code:
#!/bin/ksh
ip=192.168.113.14
hst=rhel_server
 
flg=0
 
if [ ${flg} -eq 0 ]
then
ssh -o IdentityFile=/root/.ssh/id_dsa -t -t root@${ip} << EOF
ksh /remote_script/server_install_soft.ksh ## Interactive Script
rm /tmp/log/old_log.log
EOF
fi
exit

truncate

TRUNCATE(1)                                                        User Commands                                                       TRUNCATE(1)

NAME

       truncate - shrink or extend the size of a file to the specified size

SYNOPSIS

       truncate OPTION... FILE...

DESCRIPTION

       Shrink or extend the size of each FILE to the specified size

       A FILE argument that does not exist is created.

       If  a  FILE  is  larger than the specified size, the extra data is lost.  If a FILE is shorter, it is extended and the extended part (hole)
       reads as zero bytes.

       Mandatory arguments to long options are mandatory for short options too.

       -c, --no-create
              do not create any files

       -o, --io-blocks
              treat SIZE as number of IO blocks instead of bytes

       -r, --reference=RFILE
              base size on RFILE

       -s, --size=SIZE
              set or adjust the file size by SIZE bytes

       --help display this help and exit

       --version
              output version information and exit

       The SIZE argument is an integer and optional unit (example: 10K is 10*1024).  Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (pow-
       ers of 1000).

       SIZE  may also be prefixed by one of the following modifying characters: '+' extend by, '-' reduce by, '<' at most, '>' at least, '/' round
       down to multiple of, '%' round up to multiple of.
