I have googled around a bit and could not find an answer to how this works:

I know what each part is doing. The record is being set to equal the last field and the field separator is being set to null so that each character is considered a field. Why can FS= be... (4 Replies)

mv
mv(1) General Commands Manual mv(1)Name
mv - move or rename files
Syntax
mv [-i] [-f] [-] file1 file2
mv [-i] [-f] [-] file... directory
Description
The command moves (changes the name of) file1 to file2.
If file2 already exists, it is removed before file1 is moved. If file2 has a mode which forbids writing, prints the mode and reads the
standard input to obtain a line. If the line begins with y, the move takes place. If it does not, exits. For further information, see
In the second form, one or more files (plain files or directories) are moved to the directory with their original file-names.
The command refuses to move a file onto itself.
Options
- Interprets all following arguments as file names to allow file names starting with a minus.
-f Force. This option overrides any mode restrictions or the -i switch.
-i Interactive mode. If a move is to supersede an existing file, the system prompts youw with the name of the file fol-
lowed by a question mark. If you type a string that begins with y, the move occurs. If you type any other response,
the move does not occur.
Restrictions
If file1 and file2 lie on different file systems, must copy the file and delete the original. In this case the owner name becomes that of
the copying process and any linking relationship with other files is lost.
