Full Discussion: Hiding password from ps
Top Forums Shell Programming and Scripting Hiding password from ps Post 18915 by Perderabo on Thursday 4th of April 2002 07:37:19 AM

HP-UX stores the command line in a buffer and makes it available to all users via the pstat() system call. So disabling ps is not enough.

That buffer, like all buffers, is finite. So
ln -s /path/to/CONCSUB longname
./longname USERNAME/PASSWORD
should work. Of course, "longname" isn't long enough. You will need a 64 character name.

As to storing the password in a file, her is an alternative:
Code:
#! /usr/bin/ksh

print -n password -
stty -echo
read PASSWORD
stty echo
print

With this, the script just asks the user for the passwordeach time it runs.
