As alternative, you can use "ex", the vi engine. We have "ex" in muLinux.
It do not output anything when used in the batch mode. But, please, use
it only with the bare syntax:

                cat command_file | ex buffer

For example, this piece of code send a replacement command, then "wq"
to ex, via pipe:

                cat << END | ex buffer
                1,$ s/a/b/g

In this way, you have to open a pipe only in order to send your
commands, and 1024 bytes are enough for that.

It seems that "ex" do not accept multiple commands, without a newline.

It is not urgent!
