cd

Changes the current working directory

APPLICABILITY

SYNOPSIS

cd [ dir-pname ]

DESCRIPTION

The cd command works differently depending on whether you are using a dynamic view or a snapshot view.

Changing Directories in a Dynamic View

The cd command changes the current working directory, as does the UNIX cd(1) command. In Attache, the current directory is changed both in the workspace and the view, and is set as the command prompt in the Command Window. In ClearCase and MultiSite, this command is intended for use in interactive cleartool and multitool sessions and in shell scripts or batch files that simulate interactive sessions.

With a view-extended pathname, cd also changes your working directory view. The specified view's config spec determines which versions of elements are visible in your new working directory.

With a version-extended pathname that specifies an element or branch, cd changes your current working directory to a location in version-extended namespace, wherein element and branch names are treated like directories in a read-only file system. The best way to leave version-extended namespace is to change directories to a full pathname. Typing cd .. does not exit version-extended namespace until you ascend past the VOB root directory. (See the pathnames_ccase reference page.)

Changing Directories in a Snapshot View

The cd command changes the current working directory. If dir-pname specifies a snapshot view, cd changes the view context to that of the snapshot view.

View Selection Precedence

Regardless of the view type, view-selection precedence is as follows:

1. If you specify a a view-extended name, that view is used.

2. Otherwise, the view implied by the current directory is used.

3. Otherwise, the view that has been set (if any) is used.

Attache's Client Process Startup Directory

A separate startup directory is associated with the Attache client process. This directory changes depending on how Attache is started. For example, it is the working directory specified in Attache's program item properties if Attache is started from the icon. Once the Attache client process is started, this directory never changes.

RESTRICTIONS

None.

OPTIONS AND ARGUMENTS

SPECIFYING THE NEW WORKING DIRECTORY.  Default: Changes to your home directory in ClearCase, ClearCase LT and MultiSite; or the home directory on the helper host in Attache, determined in UNIX by examining the password database and in Windows by the value of the HOME environment variable, the value of the HOMEDRIVE and HOMEPATH environment variables, or the user profile.

dir-pname

The pathname of the directory to become your current working directory. You can specify a view-extended or version-extended pathname, as described above.

In Attache, the pathname may or may not exist locally, and may even be invalid on the local file system. No error occurs unless you try to download a file at that pathname.

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.

• Change to your home directory.

cmd-context cd

• Change to the release subdirectory of the current working directory's parent.

cmd-context cd ..\release (in Attache, type this command at a workspace prompt)

• (ClearCase/ClearCase LT/MultiSite) Use a view-extended pathname to change to the src directory in the context of the jackson_old view.

cmd-context cd /view/jackson_old/usr/hw/src

• Change to the directory in extended namespace that represents the main branch of element hello.c.

cmd-context cd hello.c@@\main (in Attache, type this command at a workspace prompt)

• (ClearCase/ClearCase LT/MultiSite) Change to a directory in extended namespace, and then return to the original directory.

cmd-context cd src@@

cmd-context pwd
/view/jackson_vu@@/usr/hw/main/2/src

cmd-context cd /usr/hw/src

cmd-context pwd
/usr/hw/src

• (Attache) Change to a directory in extended namespace, and then return to the original directory.

\vobs1\>  cd src@@

\vobs1\src@@>  pwd
\vob1\src@@

\vobs1\src@@>  cd \vob1\hw\src

\vobs1\hw\src>  pwd
\vob1\hw\src
