/usr is short for “User”, right? How come it doesn’t have user related stuff in it?
I’ve wondered this for a long time. Today I discovered while searching for some unrelated information that it in fact stands for “Unix System Resources”.
Next they’ll tell me that /etc doesn’t stand for “Eggs Toast and Coffee”. Sheesh!
Wait… before I try to copy this directory recursively, how big is it?
du -sk /path/to/directory
-s : Display only a total for each argument
-k : Display size in KB
Oh dear. I’m going to need a bigger disk.
In Linux/Unix command line you can follow a file with tail -f [filename]. As the file is updated, the screen will update. This is handy for following error logs, etc.
I just learned from a co-worker that the ‘less’ command can do the same thing if you hit shift-F while viewing a file. Apparently less does a lot more than I thought! I think point and click interface is making me soft, I need to ‘man’ up and RTFM on some command line goodies.
$man less
Alcon is an AS2/AS3 debugger written in Adobe AIR. It doesn’t care what editor, compiler, or OS you are using (yay! a Linux AS3 debugger!). Bryan from Intuitive Media (check muh blog roll) turned me on to it. FlexBuilder can go do it’s thing in Windows/Mac land and I’ll keep doing my thing over here with Linux power! Thanks Hexagon Star!
