'ifconfig' can live in various places, but usually it is in /sbin/ifconfig or /usr/sbin/ifconfig (old unixen might have it in /etc/ifconfig). The 'grep inet' should give you all the ip addresses, but will also have things like netmask. The 'grep -v 127.0.0.1' will cut out the localhost definition. The 'awk '{print $2}' should give you just the IP address, but it might be in a different field (try 3, 4, etc). I'm sure there's a way to figure out a pure zsh way to do this, but I don't know it. Also, I strongly suggest figuring this out once, stashing it in a variable ($MY_IP or some such), and just using that variable. If you're under windows, under cygwin, you're on your own, but I'd start with 'ipconfig /all'. --Jason On Sun, Jun 13, 2004 at 06:30:23PM -0700, William Scott wrote: > Timothy: > > If you are running a computer with an ip address that changes > (dynamically allocated), this will work, although it is kind of ugly: > > define an alias such as: > > alias myip="curl -s http://www.showmyip.com/simple/ | awk '{print $1}' > " > > > > I would echo the output of myip into something at login rather than > grab it off the internet every time I hit the return key. > > > If you have a static ip address, you should only have to figure this > out once.

The purest I could think of was eliminating awk, which can be done like this: foo=`ifconfig | grep inet | grep -v '127.0.0.1'` baz=($=foo) Now $baz[2] contains the ip address. I guess you could get the address by poking /proc, but that's not very portable. __________________________________ Do you Yahoo!? Friends. Fun. Try the all-new Yahoo!

Not under linux. This is still OS-dependent. With ifconfig, you probably need to filter on \d+\.\d+\.\d+\.\d+ in particular.

Well, for string manipulation, you can use zsh expressions (e.g. loops, pattern matching and string manipulation) rather than relying on sed or awk, if that is what you're asking. If you're asking whether zsh can "find out your IP address", that's a bigger problem, with no "correct" answer in the general case. For a start, do you want your host's IPv4 address or its IPv6 address? And for which interface (loopback, PPP, Ethernet, or secure tunnel)? And what if you have multiple Ethernet interfaces, or if you have multiple subnets and aliases (e.g. your machine has a "private" address as well as public address)? And so on. Although each machine has a "hostname", there are potentially many addresses that represent that host. I suppose there might be some "standard" resolver library routines that could return just a single IP address, and this would work for "most people". But, even so, my guess is that this sort of network information might still be best left as part of an optional zsh module if at all. Don't forget that zsh has a 'periodic' function that could be used to retest a host's IP address every 5 mins, for instance, as an alternative to invoking `ifconfig` every time the prompt is generated. ^ permalink raw reply [flat|nested] 7+ messages in thread

This shows my public IP address (the official internet IP given to me by my ISP when I am dialed up). [My apologies for being too vague.

I'm actually on two private LANs (one home and one work)... home uses 10.x.x.x and work uses 192.168.x.x but they are both given out via DHCP. Right now the ugly hack I have is this: ifconfig en1 | fgrep 'inet ' | awk '{print $2}' which works for the Mac, but it would have to be ifconfig eth0 | fgrep 'inet ' | awk '{print $2}' |\ sed 's/addr://' on Fedora, and possibly even something ELSE for FreeBSD. Obviously less than ideal to have to keep hacking several different ways of doing this, but if that's the only way... > On Mac OS X you can find this in the System Preferences > under file sharing or network settings (I am assuming this on the basis > of the Micro$oft email stamp at the bottom of your email.) Ah yes, sorry about that. I saved about $340USD by waiting for Office:2004 to hit the Microsoft employee store, so I've been using the demo version while waiting. I should have an official copy soon (aside: I've never liked Word or Office but Office:Mac 2004 is quite nice). [no, I'm not an MS employee, but a friend of mine is] Anyway, I'm running zsh on Fedora, FreeBSD, and Mac OSX. (I actually just got my old Dell 7500 setup to dual boot XP/Fedora/FreeBSD today, which is what prompted the question. I'm all of a sudden going to need/want to know several bits of information which I haven't needed to know before. The real challenge is going to be to see if I can write one .zshrc which I can use on all my difference zsh shell accounts by use of conditional statements. > This alias and a whole bunch of stuff that is useful for OS X zsh is > distributed by Gary Kerbaugh.
