How do I get the IP from this output?

[shelter]

I've been trying to find some information on how to "parse" text, I usually manage to figure things out but not this time.
I just want the IP from roadshow, all I've found is ShowNetStatus which outputs this:

Network status summary
Local host address = 192.168.100.13 (on interface 'Prism2')
Default gateway address = 192.168.100.1
Domain name system servers = 192.168.100.1, 192.168.100.1

But how do I script so it just outputs the IP (host address)?

Hi Shelter!

Maybe you could write your own program (in C?) that could output only your IP address or use something like this?

Cheers!

Is there a way to parse it through 'Type' or something so it outputs the first line only?

You can use GetIP (AmiTCP, Miami, RoadShow) or GetIPAddress (For everything + WinUAE) from Flype's GitHub

Wow. I searched for such a program but I don't find any. Thanks.
I actually thought about writing something myself but I don't know C that well.

Here a ShowNetStatus ARexx script version without error checking just for the record:

/* Get the IP from ShowNetStatus */

ADDRESS COMMAND

'ShowNetStatus >RAM:tempout'

CALL OPEN('tempfile', 'RAM:tempout', 'R')
CALL READLN('tempfile')
str = READLN('tempfile')    /* read the second line */
CALL CLOSE('tempfile')
PARSE VAR str . . . . ip .    /* get the fifth word */
SAY ip
'delete RAM:tempout'

[mfilos]

It needs one more dot on that line:
PARSE VAR str . . . . ip . /* get the fifth word */

cause you get the " = " in output (at least on my 3.2.1 setup).

Also deleting the RAM:tempout gives an error that is in use.
I even put a delay of 1 sec and still same.
if you delete outside the script it works just fine... weird

Thanks for testing and correction! Such things happen if you don't test it. The missing dot must be ate by Pacman. For the missing CLOSE() I haven't an excuse. However, fixed it. Should work now.

[mfilos]

Yep it should be fine.
I don’t know arexx but learning slowly although I remembered from other languages you need to close the file cause on delete is still open

[idrougge]

If you use PIPE: for output and input, you won't have to deal with deletion or closing files.

Thanks, here's something simple I wrote for GetIP to put the IP in environment variables.

set IP `GetIP`
; Outputs IP: <yourip>
setenv net_txtip "IP:" `get IP`
; Outputs <yourip>
setenv net_ip `get IP`

But the ARexx code might be better since it doesn't rely on GetIP, just ShowNetStatus which comes with RoadShow.

I use that for displaying my IP on the titlebar as well

FailAt 21
C:GetIPAddress >ENV:IP
If Warn
  Echo "" >ENV:IPBar
Else
  Echo "IP: $IP" >ENV:IPBar
EndIf

I always display the IPBar variable. If no network stack is online, nothing is shown. If yes, then the IP: xxx.xxx.xxx.xxx is shown

This is a script on S: that I execute everytime on Network-Startup and Network-Shutdown script so I always have the correct IP on titlebar

Does anyone know an alternative for uae4arm (android)?

I've tried the tools mfilos linked but it seems that uae4arm is too old and therefore doesn't has the required flag.

From the GetIPAddress source:

For now, this wont work on the UAE TCP/IP implementation,
because it does not handle the ioctl() flag "SIOCGIFCONF".
