sponge, a great *nix tool part of moreutils:
sponge: soak up standard input and write to a file
Now need to figure out how to get it on Tumbleweed; maybe http://rpm.pbone.net/index.php3/stat/4/idpl/23781842/dir/opensuse/com/moreutils-0.48-1.1.i586.rpm.html

Woofis a small simple stupid webserver that can easily be invoked on a single file. Your partner can access the file with tools he trusts (e.g. wget). No need to enter passwords on keyboards where you don’t know about keyboard sniffers, no need to start a huge lot of infrastructure, just do a
$ woof filenameandtell the recipient the URL
woofspits out. When he got that file,woofwill quit and everything is done.And when someone wants to send you a file,woofhas a switch to offer itself, so he can get woof and offer a file to you. …
Woofneeds Python on a unix’ish operating system. Some people have used it successfully on Windows within thecygwinenvironment.

Works from homebrew on OS X.

Since quite a few commands that you regularly see mentioned on the web have been removed from OpenSuSE net-tools, I’ve created a few bash aliases in /etc/bash.bashrc.local below.
Note the original commands are not good have been deprecated for years on various distros and therefore removed:
# stuff removed from net-tools # see https://features.opensuse.org/317197 and https://build.opensuse.org/package/view_file/network:utilities/net-tools/net-tools.changes ## Because of changes on Thu Apr 10 12:33:41 UTC 2014 alias "arp=echo 'use \"ip neigh\" or \"ip -r neight\"' && ip neigh" alias "ifconfig=echo 'use \"ip a\"' && ip a" alias "netstat= echo 'use \"ss\" or \"ss -r\"' && ss" alias "route=echo 'use \"ip r\"' && ip r" ## Because of changes on Sun Mar 29 00:41:21 UTC 2015 alias "ipmaddr=echo 'use \"ip maddr\"' && ip maddr" alias "iptunnel=echo 'use \"ip tunnel\"' && ip tunnel"
Some bits of the net-tools change-log:
------------------------------------------------------------------- Sun Mar 29 00:41:21 UTC 2015 - jengelh@inai.de - ipmaddr and iptunnel are obsolete too, move them to subpackage. (Superseded by `ip maddr` and `ip tunnel`) - remove redundant %clean section ------------------------------------------------------------------- Thu Apr 10 12:33:41 UTC 2014 - mmarek@suse.cz - Move arp, ifconfig, netstat and route to a -deprecated subpackage (fate#317196, fate#317197) - Drop the rarp tool, which has been broken since kernel 2.3
Note that the -lntu parameter seems to be the same for both ss and netstat: [WayBack] Get a list of Open Ports in Linux – Super User

I bumped into a disk full issue again because of the btrfs/snapper combination in openSuSE and df basically lying about the disk space, so I w rote this Nice diskinfo alias showing du, df, btrfs, parted, lsblk.
You can combine this with A bash script to btrfs snapshot details like disk sizes (requires btrfs quota to be enabled) to find out which snapper snapshots take up a truckload of space and might be safely removed.

Since ESXi is based on busybox, it is using ash a variation of sh (the classic bourne shell) called Almquist shell and most nxes use some form of bash a lot of things won’t work.
For instance, doesn’t support sh –version.
Luckily there are uname -mrs and (more elaborate) vmware -vl to get the version.
Note there is support busybox aliases so alias dir=”ls -laF” works, and you can define aliases for the version information too.

Last friday I updated the examples at *nix networking – lsof: How to tell what process has a specific port open on Linux (via: Server Fault) as I needed to document some of the machines around here (so it becomes easier replacing them).
I also added some links to background information and (when I get to using it: OS X still goes without) a good iproute2 starter page.

If for instance your Boxee gets old or breaks down, you can use a Raspberry Pi as a replacement with Kodi as media player.
This combination will understand the Video+USB over HDMI which most TV supports officially named HDMI-CEC , but most vendors “invented” their own names (see list below).
The core is the kodi support for CEC.
Basically it comes down to using three cables going to the Pi: Power from TV (or some other source), HDMI to TV, and wired Ethernet. And a distribution for RaspberryPi containing kodi will work, for instance from OpenELEC Mediacenter – Download: Raspberry Pi Builds
Chad MILLER has more details on how to get this to work: My Boxee box is getting old, but I knew of no replacements. The problem is I …
Names known for HDMI-CEC via Wikipedia:
Anynet+ (Samsung), Aquos Link (Sharp), BRAVIA Link and BRAVIA Sync (Sony), HDMI-CEC (Hitachi), E-link (AOC), Kuro Link (Pioneer), INlink (Insignia), CE-Link and Regza Link (Toshiba), RIHD (Remote Interactive over HDMI) (Onkyo), RuncoLink (Runco International), SimpLink (LG), T-Link (ITT), HDAVI Control, EZ-Sync, VIERA Link (Panasonic), EasyLink (Philips), and NetCommand for HDMI (Mitsubishi).
