execute your commands hiding secret bits from history records

read -e -s -p "Password: " password
wget --user=username --password="$password" http://example.org/ Instead of hiding commands entirely from history, I prefer to use "read" to put the password into a variable, and then use that variable in the commands instead of the password. Without the "-e" and "-s" it should work in any bourne-type shell, but the -s is what makes sure the password doesn't get echoed to the screen at all. (-e makes editing work a bit better)

What Others Think

its not so important to hide the passwords at own history file, but its more important to hide it at /proc, and without selinux extension all typed command is spectable via /proc (while they are running) Anyway, many commandline tools supports password read from terminal, such as wget and curl.
