.write does not seem to work about rappel HOT 5 CLOSED

So uh, apparently I forgot to implement the ui code to convert command lines into ptrace write calls three years ago and you're the first person to notice.... wups!

I'll get on that, thanks for letting me know.

I'll look into .write, but I can answer the vdso/vvar stuff now:

• http://man7.org/linux/man-pages/man7/vdso.7.html
• https://lwn.net/Articles/615809/

No problem, thanks for the cool tool!

BTW will .write support cmds piped in?
Would be nice to do something like
.write 0xff8aa000 <((){objcopy -O binary -j .text `which less` $1; cat $1 } =(touch -c .))
with zsh

It would probably easier to implement .writef <addr> <file with bytes to write to memory>

.write will not support shell commands but a .writef is a possibility.

Originally I had planned on adding command line options to add other files to the initial generated elf, so you could do something like rappel --map 0x41410000 --file foo.bin and in your resulting session you'd have the contents there, but I never got around to it and unless I have a pressing need, I doubt I will. If someone wants to add this though, feel free, though the ELF generation code is kinda hairy...
