You need to change directory to the one that 'jre-6u2-linux-i586.bin'

For example, if it was on your Desktop:

[.@localhost home]$ cd ./Desktop
[.@localhost Desktop]$ mv jre-6u2-linux-i586.bin /opt

cd stands for Change Directory.
./ means the directory you're currently in.
../ means the directory above the one you're in (back).
