(Originally from OSNews.com) Apple today announced the long awaited iPhone, a device that I predicted about years 1.5 ago that it would happen (I won’t forget how a fellow editor from a Mac site emailed me to say that I am crazy after reading my blog back then). But the iPhone is real, and it’s public information now. So based on the little we know about the device so far…
Split multiple log files and monitor them with GNU tail
This may not be the most elegant way to monitor your system logs but at least you won’t need to run multiple shells. Using the GNU version of the tail command, you can view more than one log file on the screen and keep them updated in real time without interaction. Other versions of tail can only display one log at a time.
zcat broken on Mac OS X: Feature or bug?
Apparently on Mac OS X 10.4.7 (and earlier), the zcat command doesn’t work. zcat is a very useful util to read through gzip-archived system logs and usually works by just typing zcat /path/to/log.gz
However, it appears to be broken on the Mac. For example, this is actual output:
[user@host:~] zcat /var/log/system.log.0.gz
zcat: /var/log/system.log.0.gz.Z: No such file or directory
[user@host:~] zcat -S .gz /var/log/system.log.0.gz
zcat: /var/log/system.log.0.gz.Z: No such file or directory
