Thanks @chutz for the comment, for the others from the bash manpage (read is a built in command): -s Silent mode. If input is coming from a terminal, characters are not echoed. and If no names are supplied, the line read, without the ending delimiter but otherwise unmodified, is assigned to the variable REPLY. The exit status is zero, unless end-of-file is encountered, [...]

You can avoid all the stty convolution with the following shortcut: echo -n Password:; read -s; echo "$REPLY". Or with bash it is only one command: read -s -p Password:; echo "$REPLY".

@OleTange echo is a shell builtin so it does not show in the process list.

The problem is if you have echo $PASS it will be visible for someone running ps aux. It is not a problem if you are the only user on this server.

| Jun 10, 2019 at 23:08 | comment | added | Greg Glockner | -x '-tt' instructs pssh to send the -tt parameter to ssh, where it forces a pseudo-terminal allocation. This was necessary to get ssh to receive the password. | |

What does -tt do? I haven't seen this in the manual page (man parallel-ssh on Debian, Ubuntu). The -x option provides SSH connection arguments. A single "string" of arguments to SSH can also be provided with -X.

PWD is not a good example because it is already used variable which contains the current directory and it is displayed in PS1 ending up with your typed password in the shell prompt =)). replaced with PASS
