Passing a Variable to a script calling itself

问题

My Script is storing a ClearCase View in a Variable. To operate in this View, the Script needs to call itself inside the View again, after it started the View. The Code looks like this

 if($params{ViewSet} eq 'no')
    {
       # Start the View
       # Store the View in $View
       # Call the Script in the new-set View with parameter -ViewSet yes
    }
if($params{ViewSet} eq 'yes')
    {
      # Do Work inside the View
    }

The problem is, obviously the Variable $View is not defined when I call my script the second time, since it is defined in the first if loop.

Can I pass the View I stored in $View when I call the Script the second time? Setting the View before entering the if-Statements would not word, I would start the View two times then.

回答1:

Call the Script in the new-set View with parameter -ViewSet

If that involve calling cleartool setview, don't: setview spawns a subshell in which what you have defined in your script won't be visible.

When your script needs to access the dynamic view started, do use the full dynamic view path:

/view/myDynView
# under which you would see:
/view/myDynView/vobs/MyVob
