pwv

Prints the working view

APPLICABILITY

SYNOPSIS

• ClearCase and Attache:

pwv [ -s·hort ] [ -wdv·iew | -set·view | -root]

• ClearCase LT:

pwv [ -s·hort ] [ -wdv·iew | -root]

DESCRIPTION

The pwv command lists the view-tag of your current view context, or ** NONE ** if there is none. There are two kinds of view contexts, as follows:

• The working directory view context, which any view may have

• The set view context, which only a UNIX dynamic view may have

NOTE: This command does not require a product license.

Dynamic Views

You can establish or change your dynamic view context by

• Using the setview command (UNIX)

• Changing to a Windows view drive

• Changing your working directory to a view-extended pathname (see pathnames_ccase).

On UNIX, if you use setview and change your working directory to a view-extended pathname, you have two view contexts: your working directory view, which is used to process simple file names and relative pathnames; and your set view, which is used to process full pathnames (those that begin with a slash. On Windows, there is no notion of a set view context.

Snapshot Views

You can establish or change your snapshot view context when you change to a snapshot view directory. There is no notion of a set view context for a snapshot view.

RESTRICTIONS

None.

OPTIONS AND ARGUMENTS

LISTING FORMAT.  Default: The annotation Working directory view: or Set view: precedes a view's view-tag.

-s·hort

Omits the annotation string. Specifying -short invokes -wdview also, unless you use -setview.

WORKING DIRECTORY VIEW VS. SET VIEW.  Default: Lists both your working directory view and your set view, unless you specify -short.

-wdv·iew

Lists your working directory view only.

-set·view

Lists your set view only. There is no notion of a set snapshot view, so when you work in a snapshot view, the set view is always ** NONE **.

MISCELLANEOUS

-root

Returns the root directory path of the current working view. This root is the portion of an element's absolute path that precedes the VOB tag.

NOTE TO UNIX USERS: Use the root directory path as the prefix for element paths in build scripts originally developed to work in a dynamic view that you now want to use in a snapshot view.

If you start a dynamic view (see startview) and then change to the view (rather than using setview), this option returns the extended view path. This option returns nothing when issued from a set UNIX dynamic view (see setview), a Windows dynamic view path or a Windows snapshot view path that has been mapped to a drive (using the subst command) that is your current drive.

EXAMPLES

The UNIX examples in this section are written for use in csh. If you use another shell, you may need to use different quoting and escaping conventions.

The Windows examples that include wildcards or quoting are written for use in cleartool interactive mode. If you use cleartool single-command mode, you may need to change the wildcards and quoting to make your command interpreter process the command appropriately.

In cleartool single-command mode, cmd-context represents the UNIX shell or Windows command interpreter prompt, followed by the cleartool command. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt. In Attache, cmd-context represents the workspace prompt.

NOTE: In the UNIX examples that follow, arguments and output that show multicomponent VOB tags are not applicable to ClearCase LT, which recognizes only single-component VOB tags. In this manual, a multicomponent VOB tag is by convention a two-component VOB tag of the form /vobs/vob-tag-leaf-for example, /vobs/src. A single-component VOB tag consists of a leaf only-for example, /src. In all other respects, the examples are valid for ClearCase LT.

On a UNIX system, list the current set view and working directory view. In this case, they are the same.

cmd-context pwv
Working directory view: jackson_vu
Set view: jackson_vu

• On a Windows system, display the current view.

cmd-context pwv
Working directory view: jackson_vu
Set view: jackson_vu

• On a UNIX system, list the working directory view only.

cmd-context pwv -wdview
Working directory view: jackson_vu

• On a UNIX system, list the current view after changing the working directory view, but before setting a view.

% cd /view/jackson_old/usr/hw/src

cmd-context pwv
Working directory view: jackson_old
Set view: ** NONE **

• (ClearCase) On a UNIX system, list the current view after setting a view and changing the working directory view.

cmd-context setview jackson_vu

% cd /view/jackson_old/usr/hw/src

cmd-context pwv
Working directory view: jackson_old
Set view: jackson_vu

• On a UNIX system, set a dynamic view, change to a VOB directory, and then use pwv -root. Notice that no value is returned.

cmd-context setview bert_dynview_v5

% cd /vobs/doc
cmd-context pwv -root
% 

• On a UNIX system, change to a snapshot view directory and get the root of the working view directory path.

% cd /usr/ssview/bert_v5/vobs/doc

cmd-context pwv -root
/usr/ssview/bert_v5

• List the current view after changing to a version-extended namespace directory. Use the short format to list the view name only.

cd src@@

cmd-context pwv -short
jackson_vu@@
