Note, there is a short story before the main course.

I recently had a customer leave. It’s never good to lose a customer. They left not because of any service issues but because its hard for them to understand that I am not a web designer. I provided hosting service for them, and I tried to make it clear that they should find a web desinger and someone to maintain their site because that is not something I specialize in or have any interest in doing. At any rate this of course leads to them finding a designer who wants to move their site to some other host.

Some projects have production code that runs off of a git cloned repository. There may be a case in which you want to notify others when that clone pulls. It is a pretty easy feat with gits post-merge hook. The post-merge hook will run after a merge (think git pull). All you have to do it create a project/.git/hooks/post-merge shell script and chmod +x it. Next time you pull successfully that script will run. Here is an example.

#!/bin/bash
TEMPLOG=$(mktemp)
echo "Sending email notification of update"
git log --reverse --no-merges --stat @{1}.. < $TEMPLOG
sendEmail -u "Production code update notification" -t recipient@domain.com < $TEMPLOG
rm $TEMPLOG

So if you have ever wanted to match a string from some given output and only print the preceding line here you go. (more…)

I spend a lot of my time sitting in front of terminals if you have not yet guessed. When dealing with different user accounts across different systems and a plethora of terminals open its nice to have a bit of information about who you are, and where you are. I also like to be able to easily differentiate output from different commands. If your interested read on.
