CP(1)CP(1)NAME
cp, fcp - copy files
SYNOPSIScp [ -gux ] fromfile tofile
cp [ -gux ] fromfile ... todir
cp-r [ -gux ] fromdir ... todir
fcp [ -R nr ] [ -W nw ] fromfile tofile
fcp [ -R nr ] [ -W nw ] fromfile ... todir
fcp -r [ -R nr ] [ -W nw ] fromdir ... todir
DESCRIPTION
In the first form, fromfile is any name and tofile is any name except
an existing directory. In the second form, the commands copy one or
more fromfiles into dir under their original file names, as if by a
sequence of commands in the first form. For example:
cp f1 f2 dir
is equivalent to:
cp f1 dir/f1; cp f2 dir/f2
Cp copies the contents of plain (non-directory) file fromfile to
tofile. The mode and owner of tofile are preserved if it already
exists; the permissions of fromfile is used otherwise. The -x option
sets the full mode and modified time of file2 from file1; -g sets the
group id; and -u sets the group id and user id (which is usually only
possible if the file server is in an administrative mode).
The -r option directs cp to copy recursively the named directories
fromdir ... to the target directory todir.
Fcp behaves like cp, but copies many blocks in parallel. It works only
with files that respect read and write offsets (see pread and pwrite in
sys-read(2)), which usually excludes files representing devices or ser‐
vices. When it applies, however, it is often much faster than cp. The
-R and -W options set the number of readers and writers (default for
each: 8).
