  • check broken links using wget as a spider

    This will visit recursively all linked urls starting from the specified URL. It won't save anything locally and it will produce a detailed log. Useful to find broken links in your site. It ignores robots.txt, so just use it on a site you own!

    wget --spider -o wget.log -e robots=off --wait 1 -r -p http://www.example.com

Pretty man pages under X
You're a developer - but it doesn't mean you have to slum it! Why not spice up your man page lookups by using a decent PDF viewer. I use 'xpdf' - maybe you prefer acroread, whatever, it's just as fast as plain dull ASCII on today's machines and you can still search for stuff - that's the main reason I use PDF and not PS.

SSH Copy ed25519 key into your host

Search inside a folder of jar/zip files
Great for finding which jar some pesky class is hiding in!

Get your commandlinefu points (upvotes - downvotes)
This will calculate the your commandlinefu votes (upvotes - downvotes). Hopefully this will boost my commandlinefu points.

exit if another instance is running
runs only one instance.

Get your default route
This gets you your default route programatically, useful for scripts

Get ethX mac addresses
I much prefer using /sbin/ip over /sbin/ifconfig for most everything. I find the interface and output to be much more consistent and it has many abilities that ifconfig, route, etc. do not. To get the mac address for only one interface, add 'show dev [interface]' to the 'ip link' part of the command: ip link show dev eth0 | grep 'link/ether' | awk '{print $2}' . Also, both this command and the ifconfig one do not require root access to run, so the sudo is not necessary.

Set Time Zone in Ubuntu
Reconfigures time zone in Ubuntu, which I cannot figure out how to do through the GUI. Worked like a charm to set my time zone to CEST from EDT.

List total available upgrades from apt without upgrading the system
This let's you find out the total packages that have available upgrades. Usefull if you want to check or show the total available upgrades on your system.

kill some process (same as others) but parsing to a variable
Kills a process matching program. I suggest using $ pgrep -fl program to avoid over-killings Nice the following: kills all bash process owned by guest $ pkill -9 -f bash -u guest
