[tlug] Bashing away at Unix

[Brian Chandler <brian@example.com>]

(Um, this is not Linux, but FreeBSD, on my pair.com webserver.)

Well, I am trying. Yesterday I learned to make a bash script to do 
something useful (about 25 years after I should have), but I only seem 
to be able to run myscript by typing:

./myscript

Even though the permissions are set to 700. But I see that . is not in 
the current value of $PATH, but I also see that in a file .profile in my 
home directory it sets PATH to _include_ .  - so where did . go to, or 
how should I put it back?

There's also something in .profile called umask, which I have just 
changed to 077, believing that this will cause newly created files to 
have only owner access. Logged out and in again, but touch still 
generates a file with 644 permissions.

Have I guessed wrong what .profile does?

Thanks for help...
