This panel displays information describing the attributes of a z/OS UNIX file. The Pathname field displays the path name of the selected z/OS UNIX file.

The General Information section of the panel displays these fields:

File Type

The type of z/OS UNIX file. The possible values are:

Dir: Directory
File: Regular file
Char: Character special file
FIFO: FIFO (first-in-first-out) special file

Size

The file size, in bytes.

Links

For a file, the number of hard links to the file. For a directory, the number of subdirectories.

Inode

File identification number, unique within the file system.

File Format

File format for regular files. The possible values are:

----: Not specified
bin: Binary data
nl: New line
cr: Carriage return
lf: Line feed
crlf: Carriage return followed by line feed
lfcr: Line feed followed by carriage return
crnl: Carriage return followed by new line

Last Modified

The date and time the file was last changed.

Last Changed

The date and time the status of the file was last changed.

Last Accessed

The date and time the data in the file was last accessed.

Created

The date and time the file was created.

CCSID

The coded character set identifier assigned to the file for Enhanced ASCII support.

Text Convert

A value of YES indicates the file is enabled for Enhanced ASCII automatic conversion. NO indicates the file is not enabled for automatic conversion.

The Owner section of the panel displays these fields:

File: The user ID and UID number of the owner of the file or directory.
Group: The group name and GID number of the owner of the file or directory.

The Mode Fields section of the panel displays these fields:

Permissions

The file or directory permissions, in octal format. If there are extended access control list (ACL) entries defined for the file or directory, + is displayed after the octal value.

Set User ID

A value of ON indicates the SETUID bit is on causing the effective user ID of the user process executing a program to be set to that of the file owner when this file is run.

Set Group ID

A value of ON indicates the SETGID bit is on causing the effective group ID of the user process executing a program to be set to that of the file owner when this file is run.

Sticky Bit

A value of ON indicates the sticky bit for the file or directory is set on. For files that are programs this causes z/OS UNIX to search for the program in the user's STEPLIB, the link pack area, or the link list concatenation. For a directory it means a user can only remove or rename a file or remove a subdirectory if one of these conditions is true:

The user owns the file or subdirectory
The user owns the directory
The user has superuser authority

The Extended Attributes section of the panel displays these fields:

Shared AS: A value of YES indicates that the program can run in a shared address space.
APF Auth: A value of YES indicates that the program can run APF authorized if it has been linked with AC=1.
Pgm Control: A value of YES indicates that the program can run as if it were from a program controlled library.
Shared Lib: A value of YES indicates that the program is loaded as a system shared library program.

The Audit section of the panel displays these fields:

Auditor

Shows the audit criteria for this file as defined by a user with auditor authority. The value shows three characters describing the audit bit settings for read, write, and execute (search) access. The possible values for each character are:

s: Audit successful access attempts
f: Audit failed access attempts
a: Audit all access attempts
-: No audit

User

Shows the audit criteria for this file as defined by the file owner or a superuser. See the field Auditor for the possible values displayed.

The Device Data section of the panel displays these fields:

Device Number

A hexadecimal number that uniquely identifies the mounted file system for this file.

Major Device

For a character special file, this is a number that identifies the device type. The possible values are:

1: Master pseudo-TTY device, which is tied to a slave device by the minor number
2: Slave pseudo-TTY device, which is tied to a master device by the minor number
3: Controlling terminal TTY
4: Null file
5: File descriptor file, which is tied to a file descriptor by the minor number
6: UNIX domain socket name special file
9: System console file

Minor Device

A number that identifies a specific device of a given device type.

The Modify action bar choice provides these options:

Mode Fields: Displays the Modify z/OS UNIX File Mode Fields panel where you can update the mode fields for the currently displayed file.
Extended Attributes: Displays the Modify z/OS UNIX File Extended Attributes panel where you can update the extended attributes for the currently displayed file.
