Here you go,
For example you want to move abc123 from one directory(BASIS) to another(ABAP)
mv <source> <destination>
mv /BASIS/abc123 /ABAP/
To do a copy, go to the source directory and send it off from there
cp /BASIS/abc123 /ABAP/
Use delete command very wisely
cd /BASIS... to a ls command to list the files
rm abc123
Hope this helps
