loadays talk

Some people convinced me to do a talk^Wtutorial tomorrow at loadays. It will be about bash!

Maybe I will use some slides from this downloadable pdf (50KB).

Content will come from the linux-training.be project (but that website stalled since February due to a redesign of our build-system). People that go to loadays can download the newest (1MB) pdf here.

strange (Open)Solaris PATH behavior

The PATH variable usually does not contain the . directory, which means files in the . directory cannot be executed without ./ afaik

$ cat w.cmd
who
$ PATH=/usr/bin
$ w.cmd
-bash: w.cmd: command not found

But then this happened on Solaris 10:

$ PATH=/usr/bin:
$ w.cmd
paul       pts/2        Sep 22 20:20    (192.168.1.34)
$

Note the colon at the end of the PATH variable. I tested this in Solaris 10 and OpenSolaris, both in Korn and bash. Why does it allow execution from within the current directory ?
(This feature/bug does not work in Linux btw)
