I am using Capture::Tiny to run an external command, but the command requires a password to be passed in as an argument and that makes it visible to other users on the system. The command can also accept arguments via STDIN which would avoid this security problem, but I haven't been able to figure out how to do this with Capture::Tiny. If I have the password as a variable in my script, how can I pass this into STDIN for external command using Capture::Tiny. The pod says Capture::Tiny supports custom filehandles, but the filehandles must be read/write and seekable. Is it possible to use a scalar as an IO::File that would work for this case?
