     36 .SH NAME
     37 cp \- copy files
     38 .SH SYNOPSIS
     39 \fBcp\fR
     40 [\fB\-adDfiHLpPrRs\fR] [\fB\-b\ \fIsize\fR]
     41 \fIfile1\fR [\fIfile2\fR .\ .\ .\ ] \fItarget\fR
     42 .SH DESCRIPTION
     43 .I File1
     44 is copied onto
     45 .IR target .
     46 If
     47 .I target
     48 is an existing regular file,
     49 its content is overwritten.
     50 Its mode and owner are preserved;
     51 the mode of the source file is used otherwise.
     52 .PP
     53 If
     54 .I target
     55 is a directory,
     56 one or more files are copied
     57 into the directory with their original file-names.
     58 .PP
     59 .I Cp
     60 refuses to copy a file onto itself.
     61 .PP
     62 The
     63 .I cp
     64 command accepts the following options:
     65 .TP
     66 .B \-i
     67 .I Cp
     68 will ask for confirmation
     69 before overwriting an existing target file.
     70 For
     71 .B /usr/5bin/cp
     72 and
     73 .BR /usr/5bin/s42/cp ,
     74 .I cp
     75 will also ask for confirmation before overwriting a directory
     76 with the
     77 .I \-r
     78 or
     79 .I \-R
     80 option.
     81 For
     82 .BR /usr/5bin/cp ,
     83 this flag will be automatically disabled
     84 if standard input is not a terminal.
     85 .TP
     86 .B \-p
     87 .I Cp
     88 will try to preserve access and modification times,
     89 user and group ownerships,
     90 and file permission bits.
     91 Failing to preserve these modes
     92 is always considered an error,
     93 but only
     94 .BR /usr/5bin/s42/cp ,
     95 .BR /usr/5bin/posix2001/cp ,
     96 and
     97 .B /usr/5bin/posix/cp
     98 will print an error message.
     99 .TP
    100 .B \-r
    101 The source file operands may be directories
    102 that will be copied recursively.
    103 Symbolic links are followed.
    104 The content of all non-directory files encountered
    105 is tried to be reproduced in a regular file.
    106 .PP
    107 The following options have been added by POSIX.2:
    108 .TP
    109 .B \-f
    110 If overwriting a target file fails,
    111 .I cp
    112 will try to unlink that file and proceed.
    113 .TP
    114 .B \-R
    115 The source file operands may be directories
    116 that will be copied recursively.
    117 Special files
    118 such as block and character devices,
    119 FIFOs,
    120 and symbolic links encountered during traversal
    121 are recreated in the target hierarchy.
    122 If a symbolic link is given as an operand,
    123 its target is copied.
    124 .PP
    125 The following options have been added by POSIX.1-2001:
    126 .TP
    127 .B \-H
    128 With the
    129 .I \-R
    130 option, follow symbolic links given as operands,
    131 but do not follow symbolic links encountered during traversal
    132 of the source hierarchy.
    133 This is the default.
    134 .TP
    135 .B \-L
    136 With the
    137 .I \-R
    138 option, follow all symbolic links.
    139 .TP
    140 .B \-P
    141 With the
    142 .I \-R
    143 option, do not follow any symbolic links.
    144 .PP
    145 The following options are extensions:
    146 .TP
    147 .B \-a
    148 Perform a recursive copy and, if possible,
    149 preserve hard links as well as any attributes.
    150 This is the same as the combination of the
    151 .I \-Rdp
    152 options.
    153 .TP
    154 \fB\-b\ \fIsize\fR
    155 With this option given,
    156 .I cp
    157 performs input and output in units of
    158 .I size
    159 bytes.
    160 The default size depends on the current input file.
    161 .TP
    162 .B \-d
    163 With the
    164 .I \-r
    165 or
    166 .I \-R
    167 options,
    168 hard links between copied files are usually splitted,
    169 i.\|e. each copied file is assigned to a separate i-node.
    170 When this option is given,
    171 hard links between copied files
    172 are reproduced in the destination hierarchy.
    173 .TP
    174 .B \-D
    175 Causes
    176 .I cp
    177 to use direct i/o
    178 when copying file data.
    179 See the description of `O_DIRECT' in
    180 .IR open (2)
    181 for more information.
    182 .TP
    183 .B \-s
    184 With this option,
    185 .I cp
    186 prints i/o statistics for each single file
    187 of which data was copied.

    213 .PP
    214 A copy of a symbolic link
    215 contains the same pathname as the original.
    216 Symbolic links with relative pathnames
    217 may thus change or lose their target
    218 if copied to a different level in the file hierarchy.
