Compression

[raidenji]

I am sort of new to linux so maybe this question sounds stupid.
I have noticed that on many developers websites, that they compress there sources in both gunzip and bunzip. why is this ? I dont understand why you need 2 compression formats when they both contain the same source. It seems to me that most distro's come with both standerds. Just curious.

p.s. also where can i find my startup log? i'm having problems swithing to kernel 2.6 ( kernel panic)

They may give a choice of compression so we the user have a choice, also I think in the older versions of tar there is no j flag which lets you uncompress bz2, while there is a z flag to uncompress the .gz compression.

Though you can unzip the bz2 with bunzip which you con pipe the output of the untaring through,

tar xvf foo.tar.bz2 | bunzip

(iirc), it's not as neat as

tar xjvf foo.tar.bz2

.

As for the startup log see /var/log/messages. For hardware detection log just type 'dmesg'.
