To copy a single file in a specified directory, you can use the cp command — which stands for copy — as follows:

$ cp source target

Where:

• source is the path to the file you want to copy.

• target is the path to the directory you want to copy it into.

Note: If the last component of the target parameter is not an existing directory, the file will be copied under the specified name instead of its original name.

Example

This command will copy the index.js file located in the current working directory into the api directory under its original name:

$ cp index.js ./api
