Hiding command line input

[Guest_imported]

Is it possible to apply a mask of "****.." or even to not display altogether, text entered on the command line of of a tcl program.I need to do this and still be able to read in the string.
This is for the user to enter a password but not have it appearing on screen.

Any ideas?

Mr. Sparkle,

You can use the -hide option of the entry widget like this:

entry .e -textvariable aaa -hide *

Any characters that are typed in .e are displayed as astrisks. The readable value is stored in the variable aaa.

Jeff.

Sorry, but the script isn't using tk, I'm trying to read from the command line. :-(
