Just seeing that the first sed also gets arguments (from the sub command in backticks) that can be modified. I am not sure how this combination is handled...
And your error is a "vim" error, so it seems that this does not work at all.
Maybe you should write a "vim" macro instead!
Trying without "-i" won't save the changes in the /tmp/tmp.* file, which is required in my case. i am exploring -s option in ed as ctsgnb suggested.

Thanks

I have tried something like below, but still it doesn't work as expected:
Code:
 function submit
{
  submit 2>&1 &
  filename=`ls -rt /tmp/tmp.*|sed -n '1p'`
  ed -- ${filename}  <<-HERE
  24s!<enter description here>!$1!
  w
  q
HERE
}

The first submit command opens vi terminal with some text . In which i need to enter the description and save it. This is what i want to accomplish, but getting the below errors:

Code:
desktop% submit test
[20] 32522
933
?
desktop%
[20]  + suspended (tty output)

Any thoughts on this?

nwbpset

NWBPSET(1)							      nwbpset								NWBPSET(1)

NAME

       nwbpset - Create a bindery property or set its value

SYNOPSIS

       nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ]

DESCRIPTION

       nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by
       the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management suite of ncpfs, together with

       As another example, look at the following command line:

	 nwbpvalues -t 1 -o supervisor -p user_defaults -c |
	 sed '2s/.*/ME/'|
	 sed '3s/.*/LOGIN_CONTROL/'|
	 nwbpset

       With this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user  object
       'me'.

	 nwbpvalues -t 1 -o me -p login_control -c |
	 sed '9s/.*/ff/'|
	 nwbpset

       This command disables the user object me.

       Feel free to contribute other examples!

       nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information.
       Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons.

OPTIONS

       -h
	  -h is used to print out a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user
	  user is the user name to use for login.

       -P password
	  password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to  the  server,  nwbpset
	  prompts for a password.

       -n
	  -n should be given if no password is required for the login.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.
