On most systems, I use bash as shell, but not all systems have it, for instance the shell.xs4all.nl server uses tcsh and ESXi 4+ uses a very limited ash shell from busybox (ESX 4 had bash though).
There is this huge script that covers many shell and operating system versions (even DOS, Windows) and interpreters (python, ruby, php, etc) what shell is this which I got through Stéphane Chazelas‘s answer in linux – determine shell in script during runtime – Unix & Linux Stack Exchange
I wanted a shorter thing that works in current Linux, BSD, OS X and ESXi versions.
Some very short scripts are less reliable, for instance echo $SHELL looks nice, but isn’t always set.
Similar for echo $0 which will fail for instance if it shows as sh but in fact is a different shell in disguise.
This works for bash, tcsh and busybox sh, is a bit more precise than getting $0. It’s based on HOWTO: Detect bash from shell script – Stack Overflow:
lsof -p $$ | awk '(NR==2) {print $1}'
But on ESXi it shows this because lsof doesn’t take any parameter there and just dumps all information:
----------+---------------------+---------------------+--------+------------------
It’s because lsof on ESXi always shows this header where Cartel and World aren’t exactly well documented:
Cartel | World name | Type | fd | Description
----------+---------------------+---------------------+--------+------------------
Empirically for non VM related processes, it looks like the Cartel is the PID and World name the command.
On Linux and BSD based systems, the header looks like this, so command and PID are reversed in ESXi:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
This command then works on both ESXi, OS X, Linux and BSD assuming you can word search for the PID and noting that PID/command will be reversed on ESXi as compared to OSX/Linux/BSD:
lsof -p $$ | grep -w $$ | awk '(NR==2) {print $1,$2}'

Getting the local IP (actually IPs, but most hosts only have a single IP):
# OS X:
alias whatismylocalip='ifconfig | sed -En '\''s/127.0.0.1//;s/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p'\'''
# Linux:
alias whatismylocalip='ip a | sed -En '\''s/127.0.0.1//;s/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p'\'''
I got them via bash – How to I get the primary IP address of the local machine on Linux and OS X? – Stack Overflow
Mac OS X and BSD have ifconfig, but most Linux distributions don’t use ifconfig any more in favour of iproute2, so you use ip a (which is shorthand for ip address show) there.
Their output is similar enough for the sed to work, though. Which surprised be because I didn’t know about the -E option (it lacks in the manual Linux page but it is in the Mac OS X one) which enables POSIX extended regular expressions. In Linux this is documented as -r, but -E also works.
I learned this through the Sed – An Introduction and Tutorial which compares the various versions of sed which also explains about the -n doing no printing.

The most recent versions of Joe don’t even build from stock in OS X any more and there are no direct installers for them.
But there are two most recent older versions that have installers, and a formula recent brew based HomeBrew installation:
- joe-3.7-0.pkg – rudix-snowleopard – JOE – Rudix: The hassle-free way to get Unix programs on Mac OS X – Google Project Hosting.
- PROJECT DETAIL for Joe’s Own Editor.
- Homebrew Formulas – Joe.
After experimenting for a while without brew preferring the first over second, I’ve installed the the third as:
- The first actually installs version 3.6, but has the syntax highlighting files installed in the correct place, so you get syntax highlighting.
- The second does install version 3.7, but since the syntax highlighting files are in the wrong place: you get no syntax highlighting.
- The brew formula has an up to date joe version 4.0 and installs the syntax highlighting in the right place: you get syntax highlighting.
Before making a choice, you might want to consider reading about joe versions in JOE – Joe’s own editor / … /NEWS.md.
Having a background partially in the Linux world, I tried building joe from source on my Mac following the steps at JOE – Joe’s own editor / Discussion / joe-editor-general:Mac binary for 3.3 does not run on OS/X 10.8. It failed because the Mercurial 3.8 branch required automake and autoconf which are not available on just a Mac + Xcode. So I’m happy that others have bit the bullet and make a good HomeBrew build.
What makes HomeBrew so great is that it is based on a fully versioned git/ruby combination, allows for multiple Python versions, allows for binaries through bintray served bottles and has zillions (well, thousands) of installable formulae, all versioned.

A while ago, testssl.sh [WayBack] needed Darwin binaries (for OS X): Supply Darwin binaries + install documentation · Issue #127 · drwetter/testssl.sh [WayBack]
So I created the small Bourne shell (sh) script below to deliver them.
It allows me to update these gists:
The build script itself is in a gist as well: https://gist.github.com/f4de3937630b87753133.git [WayBack]
It helped me to contribute to these testssl.sh issues:
Not all of these binaries are in https://github.com/drwetter/testssl.sh/tree/master/bin [WayBack] as it makes the testssl.sh repository too bloated. Some (including non-OSX builds made by others) are here:
Eventually the script might get merged into https://github.com/drwetter/testssl.sh/blob/master/utils/make-openssl.sh [WayBack] as there is a Darwin switch in this commit: https://github.com/drwetter/testssl.sh/commit/6efc3e90f52e5926b0853d3b2fb221b631dcf452 [WayBack]

DNS and Mac OS X are a bit of a tricky situation as OS X can use more than the default DNS servers: its resolve can do a multi-client DNS search.
The default DNS servers can be listed like this:
scutil --dns | grep 'nameserver\[[0-9]*\]' | sort | uniq
The effective DNS server like this:
dig whoami.akamai.net | grep "^;; SERVER" | cut -c 12-
Sometimes you want to know if you have manually configured DNS servers, or only DHCP assigned ones. This statement shows that for my Wi-Fi network-service:
networksetup -getdnsservers Wi-Fi
Because of the multi-client setup, you need to run this for all network-services configured on your OS X installation. You can get the list like this:
networksetup -listallnetworkservices
I’ve not yet found a way to list only active services, as the networksetup documentation indicates the -listnetworkserviceorder option will mark inactive ones with (*), but it reality does so only for disabled ones. So this does not work:
networksetup -listnetworkserviceorder
I might one day dig into combining the output of ifconfig with networksetup to figure out a shell based solution to this question.

Thanks Adrian W for providing the below example in your answer about obtaining GLUE record information for a domain.
It is an excellent showcase for the $IFS Internal Field Separator available in any nx shell.
In this case it is used to get the TLD (top-level domain) from the domain name specified at the command-line.
After that, it obtains the name servers for that TLD, and queries the glue records there, both using dig.
Here is a little shell script which implements Alnitak’s answer:
#!/bin/sh
S=${IFS}
IFS=.
for P in $1; do
TLD=${P}
done
IFS=${S}
echo "TLD: ${TLD}"
DNSLIST=$(dig +short ${TLD}. NS)
for DNS in ${DNSLIST}; do
echo "Checking ${DNS}"
dig +norec +nocomments +noquestion +nostats +nocmd @${DNS} $1 NS
done
Pass the name of the domain as parameter:
./checkgluerecords.sh example.org

Many sites giving your public IP address return a web page with a bloat of html. From the command-line, you are usually only interested in the IP-address itself. Few services return exactly that.
Below are command-line examples to provide the public IP address mostly from a *nix perspective. Usually you can get similar commands to work with Windows binaries for wget and Windows binaries for curl.
In the end, I’ve opted for commands in this format, as I think akamai will last longer than the other sites (but does not include an end-of-line in the http result hence the echo on Mac/*nix):
I’ve not tried aria2 yet, but might provide commands for that in the future.
These are the Linux permutations for akamai:
curl whatismyip.akamai.com && echo
curl ipv4.whatismyip.akamai.com && echo
curl ipv6.whatismyip.akamai.com && echo
curl ipv4.whatismyip.akamai.com && echo && curl ipv6.whatismyip.akamai.com && echo
The last two are convenient when you have both IPv4 and IPv6 configured on “the outside”.
You can replace curl with wget -q -O – (which outputs to stdout) for each command. You can even ommit the http:// (as that is the default protocol for both curl and wget).
