Text processing is fun. Well, fun if you like to beat your head against a wall. Most of the time I just string a few things together to get whatever I am doing done. Its much better to find the shortest way to do something, it spawns less processes, is more efficient and generally a good idea. So if you have ever wanted to match a string from some given output and only print the preceding line here you go.
So as I previously said I have updated to Hardy Haron and along with it comes a new kernel that does not work out of the box with vmware. You need to patch your vmnet and vmmon sources to get it working again. So I went ahead and wrote a script to make the process a bit faster.
I have a few of those directories that files tend to pile up in. I don’t need the files but I also don’t take the time to delete them. Pruning these old files is a good thing to keep your used disk space under control as well as your sanity. Find is a great tool to do this, its extremely flexible I recommend you read the man page next time your bored.
It is important to distinguish between a file or directory’s change time (ctime), access time (atime), and modify time (mtime).
Being able to send email manually seems to be a bit of a lost art. It is extremely handy to know how to use telnet to send email for testing procmail filters, and any other part of your mail system. It can also be fun to spoof email to a friend or co-worker. Read on for a quick run down.
Ok so this is the opposite of what I generally use but its been annoying me and I just figured out what was causing it so I figured I would share it. I am currently running Kubuntu Hardy Haron but this problem was present when I installed my first Ubuntu varient Gutsy Gibbon.
This is more or less going to be an addendum to my last post as well as an update to my previous screenrc post. About 5 minutes after posting I realized that my additions to my prompt broke some new additions to new screenrc settings.
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.
