Today I was setting up a new machine (running OpenSUSE 12.1, but it's not really important), and after switching the network configuration from DHCP to static IP, lost all connectivity, in and out. /etc/init.d/network restart seemed to list the right IP, yet I was getting

"unknown host"

and

"Network is unreachable"

errors while pinging. I double and triple checked all the settings – DNS and gateway were set up right. I even rebooted, but nothing worked.

Then I vaguely remembered that I ran into the same issue a few years prior and also spent hours trying to figure out what was going wrong. The solution was so incredibly simple that my geek cred should have been docked 10 points. But …

I've encountered a problem recently where I had to figure out if some checked out code is up-to-date with the svn repository, without actually running svn update. Unfortunately, svn update doesn't have a dry-run option, so I had to find another solution.

I came up with 2, depending on how detailed the information needs to be, which I'm about to share in this post.

1. If you want exact file and directory names, you can run:

svn status -u

If any files need updating, you will see a * before the file name.

svn status wc
M     wc/bar.c
A  +   wc/qax.c

svn status -u wc
M            965    wc/bar.c
       *
