suppress echo while reading input in expect
Hi all,
I tried searching for similar threads. Couldn't get any for Expect scripting.
I am trying automate a task which requires login to a machine. The user
would be prompted for the password. Now, I want this input to be hidden
from being displayed on the screen.
Is there any way, we can suppress echo to the terminal? Similar to the way
we do 'stty -echo' in shell script?
rgds,
Sudhir.

In a shell-script, is there any way to accept keyboard input (via STDIN) without having it display on the screen? I know keying in a login password sort of does this by replacing what you key with astericks (*) but I believe that's a "C" routine. I'd like to be able to... (2 Replies)

netrc(4) Kernel Interfaces Manual netrc(4)
NAME
netrc, .netrc - Specifies automatic login information for ftp
SYNOPSIS
$HOME/.netrc
DESCRIPTION
The .netrc file contains the information used by the automatic login (autologin) feature of the ftp command. It is a hidden file in your
home directory and must be owned by the user logging in, or by the root user. If the .netrc file contains a login password, the file's
permissions must be set to 600 (read and write by owner only).
The .netrc file can contain the following entries (separated by spaces, tabs, or newlines): Where host is the name of a remote host. This
entry begins the definition of the autologin process for the specified host. All following entries up to the next machine entry or the end
of the file apply to that host. This is the same as machine, except that default matches any name. There can be only one default token,
and it must appear after all machine tokens. This is normally used as follows: default login anonymous password user@site The preceding
command line gives the user automatic anonymous ftp login to machines not specified in .netrc. This can be overriden by using the -n flag
to disable autologin. Where user is the username to use at the remote host. If this entry is found, the autologin process initiates a
login using the specified name. If this entry is missing, the autologin process fails. Where password is the login password to be used.
The autologin process supplies this password to the remote server. A login password must be established at the remote host and that pass-
word must be entered in this file, or the autologin process fails and you are prompted for the login password. Where password is the
account password to be used. If this entry is found and an account password is required at the remote host, the autologin process supplies
the password to the remote server. If the remote host requires an account password but this entry is missing, the autologin process
prompts for the account password. Where macro is the name of an ftp subcommand macro. The macro definition starts on the following line
and is defined to contain all of the following ftp subcommands up to the next blank line. If the macro is named init, ftp executes the
macro upon successful completion of the autologin process.
