CP(1) CP(1)
NAME
cp, mv, ln, reccp - copy, move, or link files
SYNOPSIS
cp [ -z ] file1 file2
cp [ -z ] file ... directory
mv [ -f ] file1 file2
mv [ -f ] file ... directory
ln [ -s ] file1 file2
ln [ -s ] file ... directory
reccp [ -z ] file1 file2
reccp [ -z ] file ... directory
DESCRIPTION
In the first form of each command, file2 is any name except
an existing directory. In the second form the command
copies, moves, or links one or more files into a directory
under their original filenames, as if by a sequence of com-
mands in the first form. Thus `mv f1 f2 dir' is equivalent
to `mv f1 dir/f1; mv f2 dir/f2'.
Cp copies the contents of plain file1 to file2. The mode and
owner of file2 are preserved if it already exists; the mode
of file1 is used otherwise.
Mv moves file1 to file2. If the two files are in the same
file system, the name file1 is simply changed to file2; if
they are in different file systems, file1 is copied and then
removed. If file2 already exists, it is removed before
file1 is moved. In this case the mode of file2 is reported
if it is not writable and the standard input is a terminal.
Respond `y' (and newline) to permit removal.
Ln links plain file1 and file2. File2 becomes an alternate
name for, and is otherwise identical to, file1. File2 must
be in the same file system as file1 and must not already
exist.
Reccp copies plain files like cp, but copies directories and
their contents recursively. It attempts to duplicate link-
age and dates. When run by the super-user, it preserves
ownership and copies device files as device files.
The options are:
-z Preserve `holes'; see lseek(2).
CP(1) CP(1)
-f Forcibly remove file2 without asking.
-s Make symbolic links: record the (arbitrary) name file1
in file2. Except in special cases, such as rm(1) and
lstat (see stat(2)), subsequent references to file2 are
treated as references to file1. See link(2) for
details.
EXAMPLES
mkdir /usr1/ken; cp /usr/ken/* /usr1/ken
Place in /usr1/ken copies of all files from /usr/ken.
reccp /usr/ken /usr1
mkdir /usr1/ken; reccp /usr/ken/* /usr1/ken
Two ways to duplicate in /usr1/ken the whole file hier-
archy from /usr/ken.

DIAGNOSTICS
Cp, mv, and reccp refuse to copy or move files onto them-
selves or directories into themselves.
BUGS
Mv to a different file system is imperfect: if file1 is a
plain file links to it are broken; if it is a directory,
nothing happens.
