source [...] target [...]
The source file(s) are copied to the target file or directory. If the
target file already exists, it is either renamed to file.old
if the -b
option is given or overwritten if permissions allow. An alternate backup
suffix may be specified via the -B option's argument. If
the -d option
is given, target directories are created, and no files are
The options are as follows:
-B suffix Use suffix as the backup suffix if -b is given.
-b Backup any existing files before overwriting them
them to file.old. See -B for specifying a different backup
-C Copy the file. If the target file already exists
files are the same, then don't change the modification time of
-c Copy the file. This is actually the default.
The -c option
is only included for backwards compatibility.
-d Create directories. Missing parent directories
are created as
required. This option cannot be used with the
-B, -b, -C, -c,
-f, -p, -S, or -s options.
-f flags Specify the target's file flags. (See chflags(1)
for a list
of possible flags and their meanings.)
-g group Specify a group. A numeric GID is allowed.
-m mode Specify an alternate mode. The default mode is
set to rwxrxr-x
(0755). The specified mode may be either an
symbolic value; see chmod(1) for a description of
-o owner Specify an owner. A numeric UID is allowed.
-p Preserve the modification time. Copy the file,
as if the -C
(compare and copy) option is specified, except if
file doesn't already exist or is different, then

file is used and then renamed to be the target.
this is safer is that if the copy or rename
fails, the existing
target is left untouched.
-s install exec's the command /usr/bin/strip to
strip binaries so
that install can be portable over a large number
and binary types. If the environment variable
STRIP is set,
it is used instead.

STRIP For an alternate strip(1) program to run. Default is
INS@XXXXXXXXXX If either -S option is specified, or the -C
