vagrant - How do I call a shell function and pass it to ssh? -


so, 

echo 'echo hi;echo hello' |  vagrant ssh slave3

works fine. does, 

cat scr.sh |  vagrant ssh slave3

but want have function contents can pass on vm. like:

echo functionname |  vagrant ssh slave3

it says

-bash: line 1: functionname: command not found

i tried 

functionname|vagrant ssh slave3

with contents of function:

fn() {     echo hi }
