Your first example should work using the <> to define a "word" but only with GNU sed or GNU awk and similar enhanced SEDs and AWKs. There are SEDs and AWKs out there that have a not as broad understanding of regular expressions like the modern GNU versions.
On most Linux boxes your line should work flawless.

Afaik you will have to emulate the <word> RegExp behaviour like reddybs posted. Only thing I see is it could be written so sed is called only once, but I would go with that too, example:

Code:
$> echo "abc abcd abcde abc abcd xabc dabc"| sed '
> s/ abc / ooo /g
> s/^abc /ooo /g
> s/ abc$/ ooo/g
> '
ooo abcd abcde ooo abcd xabc dabc

fs_whereis

FS_WHEREIS(1)						       AFS Command Reference						     FS_WHEREIS(1)

NAME

       fs_whereis - Reports each file server housing a file or directory

SYNOPSIS

       fs whereis [-path <dir/file path>+] [-help]

       fs whe [-p <dir/file path>+] [-h]

DESCRIPTION

       The fs whereis command returns the name of each file server machine that houses the volume containing each directory or file named by the
       -path argument.

OPTIONS

       -path <dir/file path>+
	   Names each AFS file or directory for which to return the host file server machine. Partial pathnames are interpreted relative to the
	   current working directory, which is also the default value if this argument is omitted.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The output includes a line for each specified directory or file. It names the file server machine on which the volume that houses the
       specified directory or file resides. A list of multiple machines indicates that the directory or file is in a replicated volume.

       Machine names usually have a suffix indicating their cell membership. If the cell is not clear, use the fs whichcell command to display the
       cell in which the directory or file resides. To display the cell membership of the local machine, use the fs wscell command.

EXAMPLES

       The following example indicates that volume housing the directory /afs/abc.com resides is replicated on both "fs1.abc.com" and
       "fs3.abc.com":

	  % fs whereis -path /afs/abc.com
	  File /afs/abc.com is on hosts fs1.abc.com fs3.abc.com
