Enumeration PaxTarHeaderKey

The file access time for the following file(s), equivalent to the value of the st_atime member of the stat structure for a file, as described by the stat() function. The access time shall be restored if the process has appropriate privileges required to do so. The format of the shall be as described in pax Extended Header File Times.

The name of the character set used to encode the data in the following file(s). The entries in the following table are defined to refer to known standards; additional names may be agreed on between the originator and recipient.

A series of characters used as a comment. All characters in the field shall be ignored by pax.

The group ID of the group that owns the file, expressed as a decimal number using digits from the ISO/IEC 646:1991 standard. This record shall override the gid field in the following header block(s). When used in write or copy mode, pax shall include a gid extended header record for each file whose group ID is greater than 2097151 (octal 7777777).

The group of the file(s), formatted as a group name in the group database. This record shall override the gid and gname fields in the following header block(s), and any gid extended header record. When used in read, copy, or list mode, pax shall translate the name from the encoding in the header record to the character set appropriate for the group database on the receiving system. If any of the characters cannot be translated, and if neither the -o invalid=UTF-8 option nor the -o invalid=binary option is specified, the results are implementation-defined. When used in write or copy mode, pax shall include a gname extended header record for each file whose group name cannot be represented entirely with the letters and digits of the portable character set.

The name of the character set used to encode the value field of the gname, linkpath, path, and uname pax extended header records. The entries in the following table are defined to refer to known standards; additional names may be agreed between the originator and the recipient.

The pathname of a link being created to another file, of any type, previously archived. This record shall override the linkname field in the following ustar header block(s). The following ustar header block shall determine the type of link created. If typeflag of the following header block is 1, it shall be a hard link. If typeflag is 2, it shall be a symbolic link and the linkpath value shall be the contents of the symbolic link. The pax utility shall translate the name of the link (contents of the symbolic link) from the encoding in the header to the character set appropriate for the local file system. When used in write or copy mode, pax shall include a linkpath extended header record for each link whose pathname cannot be represented entirely with the members of the portable character set other than NUL.

The file modification time of the following file(s), equivalent to the value of the st_mtime member of the stat structure for a file, as described in the stat() function. This record shall override the mtime field in the following header block(s). The modification time shall be restored if the process has appropriate privileges required to do so. The format of the shall be as described in pax Extended Header File Times.

The pathname of the following file(s). This record shall override the name and prefix fields in the following header block(s). The pax utility shall translate the pathname of the file from the encoding in the header to the character set appropriate for the local file system.

When used in write or copy mode, pax shall include a path extended header record for each file whose pathname cannot be represented entirely with the members of the portable character set other than NUL.

The size of the file in octets, expressed as a decimal number using digits from the ISO/IEC 646:1991 standard. This record shall override the size field in the following header block(s). When used in write or copy mode, pax shall include a size extended header record for each file with a size value greater than 8589934591 (octal 77777777777).

The user ID of the file owner, expressed as a decimal number using digits from the ISO/IEC 646:1991 standard. This record shall override the uid field in the following header block(s). When used in write or copy mode, pax shall include a uid extended header record for each file whose owner ID is greater than 2097151 (octal 7777777).

The owner of the following file(s), formatted as a user name in the user database. This record shall override the uid and uname fields in the following header block(s), and any uid extended header record. When used in read, copy, or list mode, pax shall translate the name from the encoding in the header record to the character set appropriate for the user database on the receiving system. If any of the characters cannot be translated, and if neither the -o invalid=UTF-8 option nor the -o invalid=binary option is specified, the results are implementation-defined. When used in write or copy mode, pax shall include a uname extended header record for each file whose user name cannot be represented entirely with the letters and digits of the portable character set.
