Need another speaker!

[Matt Darby]

Dearest compadres,

Your local, loyal, loving ruby user group is in need of a speaker on the eve of May 20th. I implore you to share your wisdom and knowledge with the group. Your reward will be everlasting love and a round of applause. Your heart will grow twice fold. If you are balding, hair will grow back. Unicorns will dance and rainbows will shine out of everyone's laptops. You will achieve Nirvana. 

Cheers!

Matt Darby, M.S.

I find that some of the best topics are the things that we think are the things that everyone knows.

Things we use all the time that would save someone some heartache.

+1

Unix shell.

[Matt Darby]

Yeah, I'd love to see something on ZSH (I've used it for years and I'm sure I know < 1% of its features)

[Jon Canady]

Another +1 on UNIX shell stuff. I just found out what "set -e" does in a bash script, and it kinda blew my mind.

Cheers!

What does 'set -e' do in bash? 

[Jon Canady]

Any command in the script that fails will cause your script to immediately fail as well.

[Joe Atzberger]

Set -e is short for: 

set -o errexit

That helps when googling it.  But to get what you might reasonably expect coming from a higher level language, you should also consider adding:

set -o pipefail

Because it is not always apparent that the subshell you are invoking is failing and NOT triggering errexit.  There are also arguments against this, but a conscious decision about shell error handling is usually better than just assuming it will work.
