Similar thing is available within radare2 [1] too, it is available as a small library for different languages and called r2pipe [2].

I didn't understand the example in the README. There is no "main" in those lines, so why did grep output them?

I think they meant to type

  (gdb) shell-pipe disas | grep mov

Must be because it doesn’t make sense otherwise...I submitted a PR to fix it.

Thank you for the PR! That error was the result of copy-pasting output and typing the command manually.

nice and easy ! I remember that the piping functionality was discussed in GDB mailing list long ago, but I guess it never got accepted!

it would have allowed writing

    (gdb) disas | grep mov

instead of

    (gdb) shell-pipe disas | grep mov
