我希望将一组具有相同或不同名称的文件强制复制到同一主机上的单个目标用一个命令onn Solaris。
注意：副本应强制覆盖且非交互。
我使用清空了目标文件夹rm -rf *，然后触发了复制命令，如下所示，该命令不起作用。
ls -ltrq /opt/apps/apache-tomcat-10.0.27/webapps_16Nov2023/ROOT.war
-rwxr-xr-x 1 root root 200209070 Nov 16 15:32 /opt/apps/apache-tomcat-10.0.27/webapps_16Nov2023/ROOT.war
强制复制给我一个错误：
[root@ip-10-237-130-101 ARE_NOCO_15Jan2024_111]# cp -fT /opt/apps/apache-tomcat-10.0.27/webapps/Templates/mytemplate1.xls /opt/apps/apache-tomcat-10.0.27/webapps/ROOT.war '/opt/apps/apache-tomcat-10.0.27/webapps_16Nov2023/ROOT.war' /opt/apps/apache-tomcat-10.0.27/AUTO_BACKUP/ARE_NOCO_15Jan2024_111/
cp: extra operand '/opt/apps/apache-tomcat-10.0.27/webapps_16Nov2023/ROOT.war'
Try 'cp --help' for more information.
传递输入时另一个错误：
echo yes | cp /opt/apps/apache-tomcat-10.0.27/webapps/Templates/mytemplate1.xls /opt/apps/apache-tomcat-10.0.27/webapps/ROOT.war '/opt/apps/apache-tomcat-10.0.27/webapps_16Nov2023/ROOT.war' /opt/apps/apache-tomcat-10.0.27/AUTO_BACKUP/NOCO_15Jan2024_111/
cp: overwrite '/opt/apps/apache-tomcat-10.0.27/AUTO_BACKUP/NOCO_15Jan2024_111/ROOT.war'? cp: will not overwrite just-created '/opt/apps/apache-tomcat-10.0.27/AUTO_BACKUP/NOCO_15Jan2024_111/ROOT.war' with '/opt/apps/apache-tomcat-10.0.27/webapps_16Nov2023/ROOT.war'
[root@myhost NOCO_15Jan2024_111]# echo $?
1
此命令给我一个交互式提示：
[root@ip-10-137-150-101vNOCO_15Jan2024_111]# cp /opt/apps/apache-tomcat-10.0.27/webapps/Templates/mytemplate1.xls /opt/apps/apache-tomcat-10.0.27/webapps/ROOT.war '/opt/apps/apache-tomcat-10.0.27/webapps_16Nov2023/ROOT.war' /opt/apps/apache-tomcat-10.0.27/AUTO_BACKUP/NOCO_15Jan2024_111/
cp: overwrite '/opt/apps/apache-tomcat-10.0.27/AUTO_BACKUP/ARE_NOCO_15Jan2024_111/ROOT.war'?
cp 命令帮助：
[root@ip-10-237-120-101 ARE_NOCO_15Jan2024_111]# cp --help
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
By default, sparse SOURCE files are detected by a crude heuristic and the
corresponding DEST file is made sparse as well. That is the behavior
selected by --sparse=auto. Specify --sparse=always to create a sparse DEST
file whenever the SOURCE file contains a long enough sequence of zero bytes.
Use --sparse=never to inhibit creation of sparse files.
When --reflink[=always] is specified, perform a lightweight copy, where the
data blocks are copied only when modified. If this is not possible the copy
fails, or if --reflink=auto is specified, fall back to a standard copy.
Use --reflink=never to ensure a standard copy is performed.
The backup suffix is '~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.
The version control method may be selected via the --backup option or through
the VERSION_CONTROL environment variable. Here are the values:
none, off never make backups (even if --backup is given)
numbered, t make numbered backups
existing, nil numbered if numbered backups exist, simple otherwise
simple, never always make simple backups
As a special case, cp makes a backup of SOURCE when the force and backup
options are given and SOURCE and DEST are the same name for an existing,
regular file.
