CPY (Copy)

CPY Command syntax diagram

 

Purpose

The Copy (CPY) command copies a single object or a group of objects. By default, if the target object already exists, the copy of that individual object will fail. If the REPLACE(*YES) parameter is specified the target object is overwritten. The newly created object must be renamed if it is stored in the same directory as the original object. If it is stored in a directory other than the one that contains the original object, it can retain the name of the original object.

An object name pattern can be used to copy a group of related objects. A pattern cannot be used to copy a group of objects from one file system to another unless the names in the source meet the requirements of the target file system. For example, a file named /OBJA in QOpenSys cannot be copied to directory /QSYS.LIB/MYLIB.LIB/FILEA.FILE, because the QSYS.LIB file system requires a name in the form OBJA.MBR when writing to a file. All names found within the pattern would fail if they did not meet the requirement of name.object-type.

The Copy command can also be used to copy a directory tree where the directory, its contents, and the contents of all of its subdirectories are copied. A subtree copy will attempt to preserve as many attributes from the original objects as possible. This would make it possible to migrate data from one file system to another.

If the original object is a read-only file, (a file that has the PC read-only attribute flag turned on), and SUBTREE(*NODIR) is specified, the newly created object will not be read-only. This follows the conventions of the OS/2 hierarchical file system (HFS).

Note: When the value of the SUBTREE parameter is *NONE or *ALL, the PC read-only attribute flag will be copied. The subtree copy is intended to preserve as many attributes of the original objects as possible.

When TODIR is specified, the object is copied to that directory with the same name. The copied object is authorized the same as the original object. The user who issues the command owns the copied object if the OWNER value is *NEW.

When copying a file with SUBTREE(*NODIR) specified to the "root" (/). QOpenSys, QDLS, and UDFS file systems, the Last access date/time timestamp and the Data change date/time timestamp are preserved in the new file, and the Attribute change date/time timestamp is updated to the current time. The Last access date/time timestamp of the original file is updated to the current time. In the case of copying to a database file member (*MBR) in the QSYS.LIB

or independent ASP QSYS.LIB

file system, the Data change date/time is updated as well.

Note: If the parameter SUBTREE(*YES) is specified the Create date/time is updated as well.

This command can also be issued using the following alternative command name:

In addition to the CPY command, the Copy to Stream File (CPYTOSTMF) and Copy from Stream File (CPYFRMSTMF) commands can be used to copy between stream files and database member files or save files.

Required Parameters

OBJ
Specifies the path name of the object or a pattern to match the name of the object to be copied.

The object path name can be either a simple name or a name that is qualified with the name of the directory in which the object is located. A pattern can be specified in the last part of the path name. An asterisk (*) matches any number of characters and a question mark (?) matches a single character. If the path name is qualified or contains a pattern, it must be enclosed in apostrophes. See path names for more information on specifying path names.

Note: An object name pattern can be used to copy multiple objects only when the TODIR parameter is specified.

 

Optional Parameters

TODIR
Specifies the path name of the directory to copy the object into. When this parameter is used, the copied object has the same name as the OBJ parameter specified.

.: The object is copied to the current directory with the same name as the existing object.

directory-path-name: Specify the path name of the existing directory to copy the object into. See path names for more information on specifying path names.

TOOBJ
Specifies the path name of the copied object. This is the name of the new object, including the path or the relative path. See path names for more information on specifying path names.

SYMLNK
Specifies whether to copy the object or a symbolic link to the object.

*NO: The object, not a symbolic link to the object, is copied.

Note: If a symbolic link is encountered during the copy of a subtree, the object it points to is copied. If the symbolic link points to a directory, the directory is copied but its contents are not.

*YES: If the object being copied is a symbolic link, the symbolic link is copied, instead of copying the object that the symbolic link points to.

FROMCCSID
Specifies the method for obtaining the coded character set identifier (CCSID) for the source of the copy operation. This CCSID will be used for data conversion, if requested. This parameter is ignored if the object specified on the OBJ parameter is not a regular file. A regular file is a file that supports the integrated file system I/O operations open, read, and write.

*OBJ: Use the data CCSID of the object being copied.

*PCASCII: Use the data CCSID of the object being copied to compute a CCSID in the Microsoft Windows encoding scheme (x4105). Use this as the CCSID from which the data will be converted when DTAFMT(*TEXT) is specified. This option allows data from PCs to be converted properly, if the data was created using Microsoft Windows.

*JOBCCSID: The coded character set identifier (CCSID) from the default job CCSID is used.

from-CCSID: Specify a CCSID value between 1 and 65533.

TOCCSID
Specifies the data coded character set identifier (CCSID) for the target of the copy operation. This parameter is ignored if the object specified on the OBJ parameter is not a regular file. A regular file is a file that supports the integrated file system I/O operations open, read, and write.

*OBJ: Use the data CCSID of the object being copied. If this CCSID cannot be used by the file system that the object is being copied into, the copy operation will fail.

*CALC: Use the data CCSID of the object being copied. If this CCSID cannot be used by the file system that the object is being copied into, allow the file system to determine a different CCSID and continue with the copy.

*STDASCII: Compute a CCSID in the IBM PC Data encoding scheme (x2100), based on the source file's CCSID. Associate this CCSID with the target of the copy operation and, if DTAFMT(*TEXT) is specified, also use this CCSID for the data conversion. If this CCSID cannot be used by the file system that the object is being copied into, the copy operation will fail.

*PCASCII: Compute a CCSID in the Microsoft Windows encoding scheme (x4105), based on the source file's CCSID. Associate this CCSID with the target of the copy operation and, if DTAFMT(*TEXT) is specified, also use this CCSID for the data conversion. This option allows the resulting data to be used by Microsoft Windows applications. If this CCSID cannot be used by the file system that the object is being copied into, the copy operation will fail.

*JOBCCSID: The coded character set identifier (CCSID) from the default job CCSID is used.

to-CCSID: Specify a CCSID value between 1 and 65533. If this code page cannot be used by the file system that the object is being copied into, the copy operation will fail.

FROMCODPAG
Specifies the method for obtaining the code page for the source of the copy operation. This code page will be used for data conversion, if requested. This parameter is ignored if the object specified on the OBJ parameter is not a regular file. A regular file is a file that supports the integrated file system I/O operations open, read, and write.

Note: This keyword is replaced by FROMCCSID but the FROMCODPAG keyword can still be used. However, because this keyword may be removed in a future release, whenever possible use the FROMCCSID keyword.

*OBJ: Use the data code page of the object being copied.

*PCASCII: Use the data code page of the object being copied to compute a code page in the Microsoft Windows encoding scheme (x4105). Use this as the code page from which the data will be converted when DTAFMT(*TEXT) is specified. This option allows data from PCs to be converted properly, if the data was created using Microsoft Windows.

code_page: A code page value between 1-32767.

TOCODEPAGE
Specifies the data code page for the target of the copy operation. This parameter is ignored if the object specified on the OBJ parameter is not a regular file. A regular file is a file that supports the integrated file system I/O operations open, read, and write.

Note: This keyword is replaced by TOCCSID but the TOCODEPAGE keyword can still be used. However, because this keyword may be removed in a future release, whenever possible use the TOCCSID keyword.

*OBJ: Use the data code page of the object being copied. If this code page cannot be used by the file system that the object is being copied into, the copy operation will fail.

*CALC: Use the data code page of the object being copied. If this code page cannot be used by the file system that the object is being copied into, allow the file system to determine a different code page and continue with the copy.

*STDASCII: Compute a code page in the IBM PC Data encoding scheme (x2100), based on the source file's code page. Associate this code page with the target of the copy operation and, if DTAFMT(*TEXT) is specified, also use this code page for the data conversion. If this code page cannot be used by the file system that the object is being copied into, the copy operation will fail.

*PCASCII: Compute a code page in the Microsoft Windows encoding scheme (x4105), based on the source file's code page. Associate this code page with the target of the copy operation and, if DTAFMT(*TEXT) is specified, also use this code page for the data conversion. This option allows the resulting data to be used by Microsoft Windows applications. If this code page cannot be used by the file system that the object is being copied into, the copy operation will fail.

code_page: A code page value between 1-32767. If this code page cannot be used by the file system that the object is being copied into, the copy operation will fail.

DTAFMT
Specifies the format of the data in the file being copied.

*BINARY: The file contains data in binary format (such as an executable file).

Do not convert data on the copy. However, if the object being copied to has a different code page than the source object, all extended attributes will be converted into the code page of the new object before being set.

*TEXT: The file contains data in textual form. Convert data to the code page of the new object during the copy. The data is processed as text during the copy.

If you are copying from a database member to a stream file, any line-formatting characters (such as carriage return, tab, and end-of-file) are just converted from one code page to another.

If you are copying from a stream file to a database member, the stream file must contain end-of-line characters or the copy will fail. If the stream file does contain end-of-line characters, the following actions are performed during the copy to a database file.

  • End-of-line characters are removed.
  • Records are padded with blanks (for a source physical file member) or nulls (for a data physical file member).
  • Tab characters are replaced by the appropriate number of blanks to the next tab position.


SUBTREE
Specifies whether or not to copy a directory subtree if the object specified by OBJ is a directory.

*NODIR: The object or objects specified by OBJ are copied. If an object is a directory the copy will fail.

*NONE: The objects specified by OBJ are copied. Directory objects are copied but their contents are not copied.

*ALL: The objects specified by OBJ are copied. Directory objects are copied as well as their contents and the contents of all subdirectories.

Pattern matching on the Object (OBJ) parameter only applies to the first level object. If the first level object is a directory, the pattern matching does not apply to its contents or the contents of its subdirectories.

If SUBTREE(*ALL) is specified, individual completion messages for each object are not issued. A final message is issued to indicate how many copies succeeded and how many failed. If objects did fail to copy the command will issue a diagnostic message for each copy that failed.

There are a few differences in how attributes are copied when SUBTREE(*NONE) or SUBTREE(*ALL) is specified instead of the default SUBTREE(*NODIR). A directory subtree copy preserves as much of the original objects attributes as possible.

  • The PC read-only attribute flag is turned off in the copied object. If SUBTREE(*NONE) or SUBTREE(*ALL) is specified the flag will be copied.

  • The Create date/time timestamp will be copied if SUBTREE(*NONE) or SUBTREE(*ALL) is specified (by default it is updated to the current time).

REPLACE
Specifies whether the target object is replaced if it already exists.

*NO: The target object is not replaced if it already exists.

*YES: If the target object already exists, it is replaced. If REPLACE(*YES) is specified with a directory object, the attributes of the existing target directory are changed but the objects that the directory contains are not removed.

OWNER
Specifies the owner of the newly created object.

*NEW: The owner of the new object is the current user profile of the job.

*KEEP: The owner of the new object is the same as the owner of the original object being copied.

Some file system objects do not support changing the owner. For example, the owner of *MBR objects in the QSYS.LIB

and independent ASP QSYS.LIB file systems will be

determined by the owner of the *FILE object that they are copied into.

Examples for CPY

Example 1: Copying a File

CPY   OBJ('DECEMBER-1994-MONTHLY-PAYROLL-FILE')
  TOOBJ('PAY')

This command creates another file named PAY that is a duplicate of the file named DECEMBER-1994-MONTHLY-PAYROLL-FILE.

Example 2: Copying a File to Another Directory

CPY   OBJ('PAY') TODIR('MYDIR')

This command creates another file named PAY in directory MYDIR.

Example 3: Copying a Symbolic Link

CPY   OBJ('SL1') TOOBJ('YOURDIR/SL2') SYMLNK(*YES)

If SL1 is a symbolic link, the new object YOURDIR/SL2 is also a symbolic link. If SYMLNK(*NO) was specified, the new object would be a copy of whatever SL1 pointed to, as long as it was a legal candidate for the copy function.

Example 4: Copying with Conversion

CPY    OBJ('/DATAFB')
       TOOBJ('/QSYS.LIB/APP1.LIB/DATA.FILE/DATAFB.MBR')
       TOCCSID(*CALC) DTAFMT(*TEXT) 

The stream file 'DATAFB' is to be copied to the database file 'DATAFB.MBR'. By specifying TOCCSID(*CALC), the file system being copied to (the QSYS.LIB file system in this case) will try to create the new member in the same coded character set identifier (CCSID) as '/DATAFB'. If this fails (in this case, if 'DATA.FILE is not in the same CCSID as 'DATAFB'), the file system will be allowed to choose an appropriate CCSID and complete the copy. By specifying DTAFMT(*TEXT), the data in 'DATAFB' is handled as text and is converted into the CCSID chosen for the new file 'DATAFB.MBR'.

Example 5: Copying a Directory Subtree

 CPY    OBJ('/QDLS/MYINFO')                                       
        TODIR('/myfolder')                                        
        SUBTREE(*ALL)                                             
        OWNER(*KEEP)                                              
        REPLACE(*YES)                                             

The *FLR object (QDLS file system folder) is created in the '/myfolder' directory in the "root" (/) file system with the path name '/myfolder/MYINFO'. Its contents are copied as well. Since OWNER(*KEEP) is specified, the new objects created will belong to the same profiles as the old objects. With the REPLACE parameter set to *YES if any of the target files already exist they will be overwritten.
