To open a version not currently in your view from a command prompt using a version-extended path

About this task

Tip: This procedure assumes that if you work in a snapshot view, the element is loaded in the view.

Procedure

Start a dynamic view or change to a directory loaded into a snapshot view.

If a cleartool prompt is not already displayed, display one. To see the list of versions for an element, type the following command:

cleartool lsvtree element-path

The output of the lsvtree command uses version-extended paths to identify each version.

For example:

On UNIX systems and Linux:

% cleartool lsvtree prog.cprog.c@@/main 
prog.c@@/main/0 
prog.c@@/main/r1_fix
prog.c@@/main/r1_fix/1 
prog.c@@/main/r1_fix/2 
prog.c@@/main/1

On Windows systems:

> lsvtree prog.cprog.c@@\main 
prog.c@@\main\0 
prog.c@@\main\r1_fix 
prog.c@@\main\r1_fix\1 
prog.c@@\main\r1_fix\2 
prog.c@@\main\1

You can use standard differences tools or cleartool diff to compare versions against each other. For example:
- On UNIX systems and Linux:
```
% cleartool diff prog.c@@/main/r1_fix/1 prog.c@@/main/1
```
- On Windows systems:
```
> diff prog.c@@\main\r1_fix\1 prog.c@@\main\1
```
To open a version, do one of the following, depending on the type of view you use:
- In a snapshot view, you must use the cleartool get command to copy a version into your view. If your development application relies on specific file extensions, the -to argument of the get command must use the required extension.
  For example, the following command copies prog.c@@/main/r1_fix/1 (on Windows systems: prog.c@@\main\r1_fix\1) to prog.old.c in the current directory:
  - On UNIX systems and Linux:
```
% cleartool get -to prog.old.c prog.c@@/main/r1_fix/1
```
  - On Windows systems:
```
> get -to prog.old.c prog.c@@\main\r1_fix\1
```
- In a dynamic view, you can use this version-extended path just as you would use a standard path.
  For example, in a text editor (on a UNIX system or Linux) or in the Open window of Visual Studio (on Windows systems), you can use the file name prog.c@@/main/r1_fix/1 (on a Windows system: prog.c@@\main\r1_fix\1) to open the first version on the r1_fix subbranch.
  
  Windows tip: You must use backslashes when providing version-extended paths to Windows applications.

Results

If your development application relies on specific file extensions, use a standard copy shell command to copy the version-extended path to a file name with the required extension.
