Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

read unixtimestamp with festival

you will hear how many seconds since 1.1.1970 in english words with billions, millions and thousands.

this is very useful, if you want to get over to use the unixtimestamp instead of the 24 hour clock in your dayly life

View all date formats, Quick Reference Help Alias

If you have used bash for any scripting, you've used the date command alot. It's perfect for using as a way to create filename's dynamically within aliases,functions, and commands like below.. This is actually an update to my first alias, since a few commenters (below) had good observations on what was wrong with my first command.

# creating a date-based ssh-key for askapache.github.com

ssh-keygen -f ~/.ssh/`date +git-$USER@$HOSTNAME-%m-%d-%g` -C [email protected]' # [email protected]

# create a tar+gzip backup of the current directory

tar -czf $(date +$HOME/.backups/%m-%d-%g-%R-`sed -u 's/\//#/g' <<< $PWD`.tgz) . # tar -czf /home/gpl/.backups/04-22-10-01:13-#home#gpl#.rr#src.tgz .

I personally find myself having to reference

date --help

quite a bit as a result. So this nice alias saves me a lot of time. This is one bdash mofo. Works in sh and bash (posix), but will likely need to be changed for other shells due to the parameter substitution going on.. Just extend the sed command, I prefer sed to pretty much everything anyways.. but it's always preferable to put in the extra effort to go for as much builtin use as you can. Otherwise it's not a top one-liner, it's a lazyboy recliner.

Here's the old version:

alias dateh='date --help|sed "/^ *%%/,/^ *%Z/!d;s/ \+/ /g"|while read l;do date "+ %${l/% */}_${l/% */}_${l#* }";done|column -s_ -t'

Find out what the day ends in

Several people have submitted commands to do this, but I think this is the simplest solution. It also happens to be the most portable one: It should work with any sh or csh derived shell under any UNIX-like OS.

Oh by the way, with my German locale ($LC_TIME set appropriately) it prints "g" most of the time, and sometimes (on Wednesdays) it prints "h". It never prints "y".

Bash function to see what the day ends in

A command to find out what the day ends in. Can be edited slightly to find out what "any" output ends in.

Typing the current date ( or any string ) via a shortcut as if the keys had been actually typed with the hardware keyboard in any application.

That works in all softs, CLI or GUI... I don't want to waste time to all the time typing the same stuff . So, I have that command in my window manager shortcuts ( meta+l ). All the window managers have editable shortcuts AFAIK. If not, or you don't want to use it that way, you can easily use the xbindkeys soft.

I you're using kde4, you can run :

systemsettings

then open "inputs actions" and create a new shortcut.

For Gnome take a look there : http://www.cyberciti.biz/faq/howto-create-keyboard-shortcuts-in-gnome/

A more advanced one, with strings and newlines :

xvkbd -xsendevent -text "---8<-----\nToday date is: $(date +%Y%m%d)\n---8<-----"

For complicated or long paste, you can feed xvkbd with a file :

xvkbd -xsendevent -file <file>

You can simulate ^C ( control+c ) too or others combinations of keys :

xvkbd -text "\C\Ac"

There's no man page nor help ( On my Archlinux distro ), but you can see online doc there : http://homepage3.nifty.com/tsato/xvkbd/
