cp(1) User Commands cp(1) NAME cp - copy files SYNOPSIS /usr/bin/cp [-fip] source_file target_file /usr/bin/cp [-fip] source_file... target /usr/bin/cp -r|-R [-fip] source_dir... target /usr/xpg4/bin/cp [-fip] source_file target_file /usr/xpg4/bin/cp [-fip] source_file... target /usr/xpg4/bin/cp -r|-R [-fip] source_dir... target AVAILABILITY /usr/bin/cp SUNWcsu /usr/xpg4/bin/cp SUNWxcu4 DESCRIPTION In the first synopsis form, neither source_file nor target_file are directory files, nor can they have the same name. The cp utility will copy the contents of source_file to the destination path named by target_file. If target_file exists, cp will overwrite its contents, but the mode (and ACL if applicable), owner, and group associated with it are not changed. The last modification time of target_file and the last access time of source_file are set to the time the copy was made. If target_file does not exist, cp creates a new file named target_file that has the same mode as source_file except that the sticky bit is not set unless the user is super-user; the owner and group of target_file are those of the owner. If target_file is a link to another file with links, the other links remain and target_file becomes a new file. In the second synopsis form, one or more source_files are copied to the directory specified by target. For each source_file specified, a new file with the same mode (and ACL if applicable), is created in target; the owner and group are those of the user making the copy. It is an error if any source_file is a file of type directory, if target either does not exist or is not a directory. In the third synopsis form, one or more directories speci- fied by source_dir are copied to the directory specified by target. Either -r or - R must be specified. For each source_dir, cp will copy all files and subdirectories. OPTIONS The following options are supported: SunOS 5.5.1 Last change: 27 Jun 1995 1 cp(1) User Commands cp(1) -f Unlink. If a file descriptor for a destination file cannot be obtained, attempt to unlink the des- tination file and proceed. -i Interactive. cp will prompt for confirmation when- ever the copy would overwrite an existing target. A y answer means that the copy should proceed. Any other answer prevents cp from overwriting target. /usr/bin/cp -p Preserve. cp duplicates not only the contents of source_file, but also preserves the owner and group id, permissions modes, modification and access time, and ACLs if applicable. Note that the command may fail if ACLs are copied to a file system that does not support ACLs. The command will not fail if unable to preserve modification and access time or permission modes. If unable to preserve owner and group id, cp will not fail, and it will clear S_ISUID and S_ISGID bits in the target. cp will print a diagnostic message to stderr and return a non-zero exit status if unable to clear these bits. /usr/xpg4/bin/cp -p Preserve. cp duplicates not only the contents of source_file, but also preserves the owner and group id, permission modes, modification and access time, and ACLs if applicable. Note that the command may fail if ACLs are copied to a file system that does not support ACLs. If unable to duplicate the modification and access time or the permission modes, cp will print a diagnostic message to stderr and return a non-zero exit status. If unable to preserve owner and group id, cp will not fail, and it will clear S_ISUID and S_ISGID bits in the target. cp will print a diagnostic message to stderr and return a non-zero exit status if unable to clear these bits. -r Recursive. cp will copy the directory and all its files, including any subdirectories and their files to target. -R Same as -r, except pipes are replicated, not read from. OPERANDS The following operands are supported: source_file A path name of a regular file to be copied. source_dir A path name of a directory to be copied. SunOS 5.5.1 Last change: 27 Jun 1995 2 cp(1) User Commands cp(1) target_file A pathname of an existing or non-existing file, used for the output when a single file is copied. target A pathname of a directory to contain the copied files. EXAMPLES 1. To copy a file: example% cp goodies goodies.old example% ls goodies* goodies goodies.old 2. To copy a list of files to a destination directory: example% cp ~/src/* /tmp 3. To copy a directory, first to a new, and then to an existing destination directory: example% ls ~/bkup /usr/example/fred/bkup not found example% cp -r ~/src ~/bkup example% ls -R ~/bkup x.c y.c z.sh example% cp -r ~/src ~/bkup example% ls -R ~/bkup src x.c y.c z.sh src: x.c y.c z.sh ENVIRONMENT See environ(5) for descriptions of the following environment variables that affect the execution of cp: LC_COLLATE, LC_CTYPE, LC_MESSAGES, and NLSPATH. EXIT STATUS The following exit values are returned: 0 All files were copied successfully. >0 An error occurred. SEE ALSO chmod(1), setfacl(1), environ(5) NOTES The permission modes of the source file are preserved in the copy. SunOS 5.5.1 Last change: 27 Jun 1995 3 cp(1) User Commands cp(1) A -- permits the user to mark the end of any command line options explicitly, thus allowing cp to recognize filename arguments that begin with a -. If a -- and a - both appear on the same command line, the second will be interpreted as a filename. SunOS 5.5.1 Last change: 27 Jun 1995 4
