You were probably thinking of something like http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/bin/echo/echo.c?rev=1.10&content-type=text/x-cvsweb-markup
But you might have been using something like http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/mg/echo.c?rev=1.66&content-type=text/x-cvsweb-markup (or, ok, as you suggest in your followup you wrote while I was looking this up, maybe you were using a shell builtin echo implementation) -- Raul On Wed, Jan 11, 2017 at 10:09 PM, Pavan Maddamsetti <[email protected]> wrote: > int > main(int argc, char **argv) > { > while (argc > 1) { > puts(argv[1]); > argc--; > argv++; > } > > return 0; > } > > Here is an example of a program similar to echo, let's call it test.c, > where I want to input something like: > > ./test "hello world\05\05\05\05\05" > > Now if I use echo to do the same thing, the octal characters do not print. > > But in my program, and in fact if I just copy the source code for OpenBSD > echo into a new file and compile that, I see all the octal characters > printed out including backslashes.
