Created page with "A '''file specification''' is the path the system uses to locate and identify a file. It consists of a node name, device, directory or di..."

New page

A '''file specification''' is the path the system uses to locate and identify a [[file]]. It consists of a [[Node|node]] name, [[Device|device]], [[Directory|directory]] or directories, file name, [[File extension|file type]], and [[File version|file version]]. You do not have to include all the elements of a complete file specification.
However, you must specify enough of the file specification so that, when combined with default components, the system can locate and identify the correct file.

=Parts of a file specification=

DENVER::DKA100:[RD.PROJECTS.SAMBA]SETUP.COM;15

{| class="wikitable"
|-
! Name !! Description !! Example !! Default
|-
| Node name || Name of the node that the file is located on (or through which it should be accessed). Do not specify the node name if you are accessing a file on the same node. || DENVER:: || Current node
|-
| Device || Name of the device that the file resides on || DKA100: || The device where the [[Default directory|default directory]] resides
|-
| Directory || Directory or set of directories in which the file is located. Nested directories are separated with a period (.). You do not have to include the [[Master file directory|master file directory]] || [RD.PROJECTS.SAMBA] || The [[Default directory|default directory]]
|-
| [[File name]] || Name of the file || SETUP || None
|-
| [[File extension]] || Extension (type) of the file || .COM || [[Depends on the command|File extension]]
|-
| [[File version]] || Version of the file || ;15 || [[Depends on the command|File version]]
|}

=Network file specifications=
There are three formats for network file specifications:
* Conventional
* Foreign
* Task
In each format, the node specification can include an [[Access control string|access control string]].
==Conventional file specification==
The conventional format for files is:
node::device:[directory]filename.type;version
==Foreign file specification==
A foreign file specification is a file that does not conform to OpenVMS syntax. The format used to provide a foreign file specification is:
node::"foreign-file-spec-string"
For example:
$ COPY BOSTON::"TEST?.DAT" *
==Task file specification==
A task specification string identifies a program to be executed on the remote node. You can use task specification strings within a program to enable the program to communicate with another program on a remote node. The format used to indicate a task specification string is:
node::‘‘task-spec-string’’
This specification identifies the program TEST2 on the remote node BOSTON:
BOSTON::"TASK=TEST2"
