parameter subsitution

Now suppose we are working in directory called
"/the/path" and I want to copy some samba
files from "/mnt/cdrom/lsoft" to my current working directory, then my
command will be something like

$cp /mnt/cdrom/lsoft/samba*.rmp /the/path

Instead of giving above command I can give command as follows

$cp /mnt/cdrom/lsoft/samba*.rmp `pwd`

Here file is copied to your working directory. See the last Parameter
substitution of `pwd` command, expand it self to
/the/path. This will save my time.

how to start MySqt at boot

as root:

cd /etc/rc.d/rc3.d
ln -s /etc/rc.d/init.d/mysqld S98mysql

above was done on fedora 4 which has the same structure as Red Hat.
How does it work? /etc/rc.d/init.d contains scripts to start and stop
services on your computer. By creating a symlink to mysql startup
script in /etc/rc.d/rc3.d you're telling your system to run it during
runlevel 3 startup, which is your regular login. You can also start
and stop your services manually using files in /etc/rc.d/init.d
directly,
