You can do it in awk, sed and perl. However its early and my brain
can't remember awk and sed syntax this early, so here it is in perl...
echo "email: test test test test" | perl -e 'foreach (split(/\s+/,<STDIN>)){next if
m/email/; print "$_\n"}'
the 'foreach (split(/\s+/,<STDIN>))' splits STDIN into segments based on
whitespace (\s+ means at least one but no max whitespace).
'next if m/^email/' skips any line starting with the string email
'print "$_\n"' print the buffer ($_) and a newline (\n)
The newline char is the key, that will be the same in sed,perl,awk,c, etc etc
