mtools ”utilities to access DOS disks in UNIX

mtools is a public domain collection of tools to allow UNIX systems to manipulate MS-DOS files read, write, and move around files on an MS-DOS file system (typically a floppy disk). Where reasonable, each program attempts to emulate the MS-DOS equivalent command. However, unnecessary restrictions and oddities of DOS are not emulated. For instance, it is possible to move subdirectories from one subdirectory to another. mtools can be found at the following places (and their mirrors):

mv ”moves or renames files

mv [ f ] [ i ] filename1 [ filename2 ...] target

The mv command moves a source filename to a target filename. The filename and the target may not have the same name . If target is not a directory, only one file may be specified before it; if it is a directory, more than one file may be specified. If target does not exist, mv creates a file named target . If target exists and is not a directory, its contents are overwritten. If target is a directory, the file(s) are moved to that directory.

Example A.38.

1   mv file1 newname

2   mv -i test1 test2 train

EXPLANATION

1. Renames file1 to newname . If newname exists its contents are overwritten.

2. Moves files test1 and test2 to the train directory. The “i switch is for interactive mode, meaning it asks before moving the files.
