DESCRIPTION

The following options are available:

-H

If the -R option is specified, symbolic links on the command line are followed. (Symbolic links encountered in the tree traversal are not followed.)

-L

If the -R option is specified, all symbolic links are followed.

-P

If the -R option is specified, no symbolic links are followed.

-R

If source_file designates a directory, cp copies the directory and the entire subtree connected at that point. This option also causes symbolic links to be copied, rather than indirected through, and for cp to create special files rather than copying them as normal files. Created directories have the same mode as the corresponding source directory, unmodified by the process' umask.

-f

For each existing destination pathname, remove it and create a new file, without prompting for confirmation regardless of its permissions. (The -i option is ignored if the -f option is specified.)

-i

Causes cp to write a prompt to the standard error output before copying a file that would overwrite an existing file. If the response from the standard input begins with the character ‘y’, the file copy is attempted.

-p

Causes cp to preserve in the copy as many of the modification time, access time, file flags, file mode, user ID, and group ID as allowed by permissions.

If the user ID and group ID cannot be preserved, no error message is displayed and the exit value is not altered.

If the source file has its set user ID bit on and the user ID cannot be preserved, the set user ID bit is not preserved in the copy's permissions. If the source file has its set group ID bit on and the group ID cannot be preserved, the set group ID bit is not preserved in the copy's permissions. If the source file has both its set user ID and set group ID bits on, and either the user ID or group ID cannot be preserved, neither the set user ID or set group ID bits are preserved in the copy's permissions.

For each destination file that already exists, its contents are overwritten if permissions allow, but its mode, user ID, and group ID are unchanged.

In the second synopsis form, target_directory must exist unless there is only one named source_file which is a directory and the -R flag is specified.

If the destination file does not exist, the mode of the source file is used as modified by the file mode creation mask (umask, see csh(1)). If the source file has its set user ID bit on, that bit is removed unless both the source file and the destination file are owned by the same user. If the source file has its set group ID bit on, that bit is removed unless both the source file and the destination file are in the same group and the user is a member of that group. If both the set user ID and set group ID bits are set, all of the above conditions must be fulfilled or both bits are removed.

Appropriate permissions are required for file creation or overwriting.

Symbolic links are always followed unless the -R flag is set, in which case symbolic links are not followed, by default. The -H or -L flags (in conjunction with the -R flag) cause symbolic links to be followed as described above. The -H, -L and -P options are ignored unless the -R option is specified. In addition, these options override each other and the command's actions are determined by the last one specified.

Cp exits 0 on success, >0 if an error occurred.
