CP(1) General Commands Manual CP(1)
NAME
cp - copy
SYNOPSIS
cp [ -ip ] file1 file2
cp [ -ipr ] file ... directory
DESCRIPTION
File1 is copied onto file2. By default, the mode and owner of file2 are preserved if it already existed; otherwise the mode of the source
file modified by the current umask(2) is used. The -p option causes cp to attempt to preserve (duplicate) in its copies the modification
times and modes of the source files, ignoring the present umask.
In the second form, one or more files are copied into the directory with their original file-names.
Cp refuses to copy a file onto itself.
If the -i option is specified, cp will prompt the user with the name of the file whenever the copy will cause an old file to be overwrit-
ten. An answer of 'y' will cause cp to continue. Any other answer will prevent it from overwriting the file.
If the -r option is specified and any of the source files are directories, cp copies each subtree rooted at that name; in this case the
destination must be a directory.
