Minimal command to make a copy of a file

Question

I often find myself copy-pasting long path in order to create a copy of a file

cp /path/to/file/file1 /path/to/file/file1.bkp

Is there an alternative utility that will NOT require me to type the path/to/file twice? Something like -

nameOfExecutible /path/to/file/file1 'bkp'

Note: I don't want to do a cd to file1s parent directory.

Solution

Yes,

cp /path/to/file/file1{,.kbp}

That will get expanded automatically to cp /path/to/file/file1 /path/to/file/file1.kbp

How is this Question about copying files (with cp being the solution) a duplicate of a Question about using path within mv command? I suggest this valuable Question be re-opened.

Thanks. That saves so much time! Is there a terminology for those brackets?

The bash shell is expanding the expression in the curly braces prior to exec'ing cp. You can find it covered in the bash manual, or google for "bash brace expansion"
