Your results will be in the files
A_new
B_new
C_new
...

Of course you can specify abolute path.
Code:
awk 'NR==FNR{a[$1];next}FNR==1{f=FILENAME "_new"}($1 in a){print $0 > f}' /home/anubha/ed/F /home/anubha/A /home/anubha/B /home/anubha/C /home/anubha/D /home/anubha/E

The awk code can also easyly be adapted to handle better the naming and the location of the target file i just did a quick shot here.
i use some crap version of linux....which doesnt hv sed/awk plugin installed in it....i dunno bt code doesnt wrk wid sed/awk...cn u suggst wid grep or fgrep... Smilie

unburden-home-dir

UNBURDEN-HOME-DIR(1)						   User Commands					      UNBURDEN-HOME-DIR(1)

NAME

       unburden-home-dir - unburdens home directories from caches and trashes

SYNOPSIS

       unburden-home-dir [ -n | -u | -f filter ]
       unburden-home-dir ( -h | --help | --version )

DESCRIPTION

       unburden-home-dir  unburdens  the  home	directory from files and directory which cause high I/O or disk usage but are neither important if
       they are lost, e.g. caches or trash directory.

       When being run it moves the files and directories given in the configuration file to a location outside the home directory,  e.g.  /tmp	or
       /scratch, and puts appropriate symbolic links in the home directory instead.

OPTIONS

       -f     just  unburden those directory matched by the given filter (a perl regular expression) -- matches the already unburdened directories
	      if used together with -u.

       -F     Do not check for files in use with lsof before (re)moving files.

       -n     dry run (show what would be done)

       -u     undo (reverse the functionality and put stuff back into the home directory)

       -h, --help
	      show this help

       --version
	      show the program's version

EXAMPLES

       Example configuration files can be found at /usr/share/doc/unburden-home-dir/examples on Debian-based systems and in the etc/ directory	of
       the source tar ball.

FILES

       /etc/unburden-home-dir,	 /etc/unburden-home-dir.list,	~/.unburden-home-dir,  ~/.unburden-home-dir.list,  /etc/default/unburden-home-dir,
       /etc/X11/Xsession.d/95unburden-home-dir

       Read /usr/share/doc/unburden-home-dir/README on debianoid installations or README in the source tar ball for an explanation of these files.
