Cp can copy files and directories from one place to another.
To use cp type cp in a terminal with the file (or folder) as the first argument and the destination as the second argument.
$ cp cat.png Pictures/
If you want to rename the file while copying you can add the file name to the destination like this.
$ cp cat.png Pictures/cat2.png
You can move folders but you need one extra argument and that is
-r, this stands for recursive.
$ cp -r important_files Documents/
Maybe you want to copy all the files from one folder to another, in that situation you can use a wildcard or a star
*. Wildcards can also be used to select specific filetypes or files with similar names.
$ cp * ~/Documents/
$ cp *.jpg Pictures/
$ cp photo*.jpg Pictures/
