Hide Password Entry in UNIX script:

-
We can use 'stty' to hide the password entry in UNIX command prompt, which is like entering password when you login to the UNIX.

stty:
'stty' sets options for your terminal


Ex :
  • stty erase \^h --- set the backspace as erase key
  • stty sane
  • stty


Example Script:


#!/bin/ksh
echo "Please enter the pwd:"
stty -echo
read pwd
stty echo
if [ "$pwd" == "secret" ]; then
echo "u have access"
else
  echo "access denied"
fi

Create failed for User 'TMS'. (Microsoft.SqlServer.Smo) User, group, or role 'TMS' already exists in the current database. (Microsoft SQL Server, Error: 15023)   To fix this there are two different methods depending on the version of SQL Server you are using. Both of these commands re-map the user's Security Identifier (SID) to match the sql server login's SID.   SQL Server 2008 / SQL Server 2008 R2 If you have already created the server login for the user, run this in the database with the login problem. (Change ' user'  to be the database username you wish to fix, and ' serverlogin ' is the sql server login to map the user to).  ALTER USER user WITH LOGIN = serverlogin For full details of the ALTER USER command see MSDN  http://msdn.microsoft.com/en-us/library/ms176060.aspx
