cp file1.txt newdir

cp /home/public_html/mylog.txt /home/public_html/backup/mylog.bak
Copies the mylog.txt file in the public_html directory into the public_html/backup directory as mylog.bak. The files are identical however have different names.
cp *.txt newdir
Copy all files ending in .txt into the newdir directory.
cp -r /home/hope/files/* /home/hope/backup
Copies all the files, directories, and subdirectories in the files directory into the backup directory.
yes | cp /home/hope/files/* /home/hope/files2
Copies all the files and subdirectories in files into the files2 directory. If files with the same name exist or it's prompted to overwrite the file it answers yes.
Many new versions of Linux/Unix or their variants may also be able to use copy in place of cp or have an alias setup for cp as copy.
