리눅스에서 파일이나 디렉터리를 복사할 때 사용하는 cp 명령어는 파일 및 디렉터리를 복사하거나 이름을 변경하는 기능을 제공한다. 글에서는 cp 명령어의 사용법과 다양한 옵션에 대해 정리 하였다.
1. 기본 사용법
$ cp [옵션] [원본 디렉터리,파일] [복사 디렉터리,파일]$ cp -p /home/user/file.txt /home/user/backup/
$ cp -r /home/user/dir /home/user/backup/
$ cp -v /home/user/file.txt /home/user/backup/
$ cp -i /home/user/file.txt /home/user/backup/
2. 옵션
| 옵션 | 설명 |
| -p | 원래 파일의 권한 및 소유자를 유지 |
| -r | 하위 디렉토리를 파일을 모두 복사 |
| -v | 복사 작업을 화면에 표시 |
| -i | 덮어쓰기 전에 확인 표시 |
| -a | 파일 및 디렉토리를 아카이브 모드로 복사, 파일 속성 모두 포함됨, (-dR --preserve=all 와 동일함.) |
Usage: cp [OPTION]... [-T] SOURCE DEST
or: cp [OPTION]... SOURCE... DIRECTORY
or: cp [OPTION]... -t DIRECTORY SOURCE...
Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY.
Mandatory arguments to long options are mandatory for short options too.
-a, --archive same as -dR --preserve=all
--attributes-only don't copy the file data, just the attributes
--backup[=CONTROL] make a backup of each existing destination file
-b like --backup but does not accept an argument
--copy-contents copy contents of special files when recursive
-d same as --no-dereference --preserve=links
-f, --force if an existing destination file cannot be
opened, remove it and try again (this option
is ignored when the -n option is also used)
-i, --interactive prompt before overwrite (overrides a previous -n
option)
-H follow command-line symbolic links in SOURCE
-l, --link hard link files instead of copying
-L, --dereference always follow symbolic links in SOURCE
-n, --no-clobber do not overwrite an existing file (overrides
a previous -i option)
-P, --no-dereference never follow symbolic links in SOURCE
-p same as --preserve=mode,ownership,timestamps
--preserve[=ATTR_LIST] preserve the specified attributes (default:
mode,ownership,timestamps), if possible
additional attributes: context, links, xattr,
all
-c deprecated, same as --preserve=context
--no-preserve=ATTR_LIST don't preserve the specified attributes
--parents use full source file name under DIRECTORY
-R, -r, --recursive copy directories recursively
--reflink[=WHEN] control clone/CoW copies. See below
--remove-destination remove each existing destination file before
attempting to open it (contrast with --force)
--sparse=WHEN control creation of sparse files. See below
--strip-trailing-slashes remove any trailing slashes from each SOURCE
argument
-s, --symbolic-link make symbolic links instead of copying
-S, --suffix=SUFFIX override the usual backup suffix
-t, --target-directory=DIRECTORY copy all SOURCE arguments into DIRECTORY
-T, --no-target-directory treat DEST as a normal file
-u, --update copy only when the SOURCE file is newer
than the destination file or when the
destination file is missing
-v, --verbose explain what is being done
-x, --one-file-system stay on this file system
-Z set SELinux security context of destination
file to default type
--context[=CTX] like -Z, or if CTX is specified then set the
SELinux or SMACK security context to CTX
--help display this help and exit
--version output version information and exit
