git post

I've been messing around with git lately and here are some notes

git init-db - initializes the repo
git add . - Adds file to repo
git commit -a -m "message" - commit to repo
git clone --bare projecname .git - makes a clone of the repo
git push - pushes it to the bare repo (can be done remotely)
git pull - updates the repo

grep goodness

So as a sys admin I find myself looking at logs most of the time. And with the volume and size of our mail logs its handy to know some nifty tricks about grepping logs and such. Here is one good trick I learned

tail -f <log file > | grep <thing you want to search for >

So what tail -f does is it will output the tail of the log file, and the -f switch will not stop the tail but instead it will keep the log file open which means you can watch logs happen in real time. And then you pipe it to grep which search for the thing you want to search for. Easy? I know its a life helps me do my job a little easier :)

muttrc

Just wanted to put up a sample muttrc file that i use, for those of you who don't know what mutt is, mutt is a text based email reader. Anyway here is my muttrc file

Unix Tip

Here is a good tip i learned a couple of days ago. If you are in the command line and you are using the command less like this

less filename

It will print out the content of the file on to the screen but if you hit 'v' it will bring you to your favorite editor so that you can edit your file

Mutt and Exchange - Solved

Recently i posted an entry about how some mails from mutt was going to the junkmail folder of an exchange account. That issue has now been solved, turns out it was a problem with the smtp servers on campus

This issue is now fixed although i do not know specifically how it was done. So my bad if i blamed exchange for this, although i have no idea why this would be an issue for the exchange servers. But then again there are many things that are weird when it comes to microsoft

New Job

So i got myself a new job. I am now working for the Network Engineering department on campus, and my new job spec will be to help implement, document and deploy WPA enterprise across campus.

WPA is a type of wireless encryption and the whole campus will be moving to using that, and i will be helping to deploy it out. Wish me luck!
