- NAME
- cp, cpdir - file copy
- SYNOPSIS
- cp [-pifsmrRvx] file1 file2
- cp [-pifsrRvx] file ... directory
- cpdir [-ifvx] file1 file2
- OPTIONS
- -p Preserve full mode, uid, gid and times
- -i Ask before removing existing file
- -f Forced remove existing file
- -s Make similar, copy some attributes
- -m Merge trees, disable the into-a-directory trick
- -r Copy directory trees with link structure, etc. intact
- -R Copy directory trees and treat special files as ordinary
- -v Display what cp is doing
- -x Do not cross device boundaries
- EXAMPLES
- cp oldfile newfile # Copy oldfile to newfile
- cp -R dir1 dir2 # Copy a directory tree
- DESCRIPTION
- Cp copies one file to another, or copies one or more files to a
- directory. Special files are normally opened and read, unless -r is
- used. -r also copies the link structure, something -R doesn't care
- about. The -s option differs from -p that it only copies the times if
- the target file already exists. A normal copy only copies the mode of
- the file, with the file creation mask applied. Set-uid bits are cleared
- if the owner cannot be set. (The -s flag does not patronize you by
- clearing bits. Alas -s and -r are nonstandard.)
- Cpdir is a convenient synonym for cp -psmr to make a precise copy of a
- directory tree.
