Cmd="grep 'Name:' |awk -F' ' '{print $2}'"

Hi

Is it possible to get the below code working.?

Code:
cmd="grep 'Name:' |awk -F' ' '{print $2}'|xargs -i basename {}"
echo $cmd
(
    rman target /  <<EOF1
    LIST COPY ;
    exit
EOF1
) | `$cmd`

in nutshell I want to be able to preset cmd as depending on script flow it can be different.
basically I want to use cat MYFILE|`"$cmd"`
where $cmd can differ depending on environment conditions

Thank you!

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME
zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files SYNOPSIS
zgrep [grep-flags] [--] pattern [files ...] zegrep [grep-flags] [--] pattern [file ...] zfgrep [grep-flags] [--] pattern [file ...] DESCRIPTION
zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1). The grep-flags and pattern arguments are passed on to grep(1). If an -e flag is found in the grep-flags, zgrep will not look for a pattern argument. zegrep calls egrep(1), while zfgrep calls fgrep(1). EXIT STATUS
In case of missing arguments or missing pattern, 1 will be returned, otherwise 0. SEE ALSO
egrep(1), fgrep(1), grep(1), gzip(1), zcat(1) AUTHORS
