I am using Redhat 5.4 and when I tend to change Oracle user password this comes up right after hitting Enter:

passwd oracle
Retype new UNIX password: 
passwd: all authentication tokens updated successfully.
[root@server~]# H0!gh%12
-bash: H0!gh%12: command not found

** it is not accidental type of the password.**

Why "H0!gh%12" comes up and how I can get rid of it?!

This is just a theory, but it looks like someone might have aliased the passwd command (poorly, in this case) on your machine, possibly to avoid having to enter the password in twice. The correct sequence for a password exchange should be:

[17:09:50][root@test1][/root]# passwd tester1
Changing password for user tester1.            ## Notice that your exchange
New password:                                  ## is missing these lines
Retype new password: 
passwd: all authentication tokens updated successfully.
[17:10:40][root@test1][/root]#

If an alias is "eating" the first two lines of the exchange in order to save your input and spit it back out to the passwd command, you might be able to find it by using the alias or set commands to determine if there are system-wide aliases. Alternatively, you could check and see if someone has replaced the passwd command with a shell script by using the file command.

[17:19:17][root@test1][/root]# file $(which passwd)
/usr/bin/passwd: setuid ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped

If it's not a setuid ELF executable - either 32- or 64-bit - then shenanigans have been pulled.

Good luck.
