Utilizes shell expansion of {} to give the original filename and a new filename as arguments to `cp`. Can easily be extended to make multiple copies.

Know a better way?

If you can do better, submit your command here.

What others think

Works well in a bash 'for' loop to create a backup of multiple files:

for file in *.txt; do cp $file{,.bak}; done;
