Use : and remove \, ' and =!

[radare]

I think that the current use of ':' is not fair enough to be that accessilble, and can be easily delegated to #: for example without making the command parser more complicated.

The idea is to have a single char to run commands thru io->system. this is heavily used in r2frida and will be good to have it easy to use from any keyboard layout.

The problem i see is with .: because we would want to run the output of that command and right now .: is for tcp :

[0x00000000]> .:?
Usage: .:[tcp-port]    run r2 commands for clients

this one can be probably renamed to .=9090 . see also:

servers:
| .:9000                        start the tcp server (echo x|nc ::1 9090 or curl ::1:9090/cmd/x)
| =:port                        start the rap server (o rap://9999)
| =g[?]                         start the gdbserver
| =h[?]                         start the http webserver
| =H[?]                         start the http webserver (and launch the web browser)
| ==[fd]                        open remote session with host 'fd', 'q' to quit

here we have a conflict but maybe we can just ignore the = ones. and make those commands like this: (consistent with = and not using :

| =t 9000                        start the tcp server (echo x|nc ::1 9090 or curl ::1:9090/cmd/x)
| =r [9999]                     start the rap server (o rap://9999)

The problem with =! is that is confusing with != and =!= and !=!. so we can probably remove them despite it is useful to enter into a remote io shell

I really got used to \ for io, especially in r2frida. Not a big fun of suddenly changing all these commands, but any change will be well accepted by me. Why is there this need of changing it? Lets keep only \?

\ is used for escaping especial chars, it's problematic for the new shell parser because it makes it more complex (one extra exception.

@enovella what do you mean? I don't see any command that has \. Does r2frida adds commands with \?

[radare]

I prefer ‘ than . In ES layout is 1 key instead of 2. Backslash conflicts with escaping

I have removed it from the 4.6 milestone because I think it's not an urgent issue to fix and it requires further discussion and feedback from the community.

At least \ seems really bad.
