Linux command and eof in one line

Issue

I want to ask if is possible to combine linux command and <

sendmail -S "lalalal" -f "dailaakak" -au "kakakak" <<EOF
>lalal:lalal
>opp:ttt
>ggg:zzz
EOF

I want to have something like that sendmail -S "lalalal" -f "dailaakak" -au "kakakak" <<EOF; lalal:lalal; opp:ttt; ggg:zzz; EOF

I need to use that not in bash script

Solution

If it has to be in one line without newlines use that:

echo -e "lalal:lalal\nopp:ttt\nggg:zzz" | sendmail -S "lalalal" -f "dailaakak" -au "kakakak"

echo -n interpretes escapes characters such as \n as a newline.
