.SH DESCRIPTION
The utilities
.BR cp ,
.BR mv ,
.BR rm ,
and
.B ln
do basic file management: copying, renaming or moving, deletion, and
creating links.
.PP
The first synopsis form of the utilities
.BR cp ,
.BR mv ,
and
.B ln
is used if only two arguments are given, and the second argument is not a
directory.  The source and target file are then the two files given.
.PP
If the second synopsis form is used then the last argument must be a
directory.  Each of the files is copied, moved or linked into this directory.
.PP
A file is by default copied by
.B cp
looking at its type; symlinks are not followed but copied, and devices are also
duplicated.  Links between files are not ignored.
.PP
The
.B mv
utility uses the
.BR rename (2)
call to rename or move files.  If source and target are on different devices
however, then
.B mv
will copy the files or directory trees.
.PP
Each utility continues with the next file on errors, except on I/O errors.
.SS OPTIONS
.TP
.B \-i
Ask if ok to overwrite, replace or remove.
.B Mv
and
.B rm
will ask this automatically if interactive and the target file is writable.
.B Cp
will fail if the target cannot be written,
.B ln
will always fail if the target exists.
.TP
.B \-f
Makes
.B cp
remove a target file before copying if it is not writable,
.B mv
removes an existing target without asking,
.B rm
does not report any errors, and
.B ln
removes an existing target file before linking.
(Not implemented in ELKS for
.B mv
or
.B ln
).
.TP
.B \-s
Make a symlink instead of a normal link.
.TP
.BR \-r ", " \-R
Recursively copy or remove.  If the source is a directory then the
files in this directory are copied to similarly named files in the target
directory.  Special files are copied as new special files, they are not read
or written.  Symlinks are still expanded and the link structure ignored with
.BR \-R .
The
.B \-r
flag does copy symlinks as symlinks and keeps the link structure intact.
(Note that
.B \-R
is invented by \s-2POSIX\s+2 as a replacement for the classic
.B \-r
option of older copy commands that did read special files.  The standard
says that
.B \-r
is implementation defined, so that's why this flag is better than
.B \-R
in this implementation of
.BR cp .)
For
.B rm
the
.B -r
option must be used.
.TP
.B \-v
Verbose.  Show what is done on standard output.
.SH "SEE ALSO"
.BR cat (1),
.BR mkdir (1),
.BR rmdir (1),
.BR link (2),
.BR symlink (2),
.BR unlink (2),
.BR rename (2).
.SH NOTES
All the utilities described are links to the same program (not in ELKS).
.SH BUGS
.B Mv
should first copy a tree across devices and then remove the source tree if
there was no error.  Instead, each file in the tree is copied and
immediately removed.  On error you may be left with two half-filled trees,
together containing all of the files.
.PP
On ELKS, comments above about recursive symlinks and copying or moving
across filesystems aren't implemented.
.PP
.B Rm
should be able to remove arbitrarily deep trees, but can fail on ELKS
due to lack of L1 internal buffer space.
