Issue in using variable within sed command
Hi All,

I am trying to use a variable within the sed command but I am not able to get the output.

When I am using the following command (without variable) its working fine:
Code:
sed -n '/2011\/12\/10 18:11:11./,$p' < Log.txt > Delta_Log.txt

But when I am putting the value 2011\/12\/10 18:11:11. in variable date_str and then use the variable, there is no output.

Have tried the following syntax's:
Code:
sed -n '/$date_str/,$p' < Log.txt > Delta_Log.txt

Code:
sed -n '/"$date_str"/,$p' < Log.txt > Delta_Log.txt

mcd

mcd(1)							      General Commands Manual							    mcd(1)

NAME

       mcd - mtools utility to change or report the DOS working directory

SYNOPSIS

       mcd [msdosdirectory]

DESCRIPTION

       Without arguments, the mcd command reports the current device and working directory.  Otherwise, the mcd command changes the current device
       and current working directory relative to a DOS file system.  Unlike the DOS command CD, the mcd command can be used to change  to  another
       device.

       The  environment  variable  MCWD  can be used to locate the file where the device and current working directory information is stored.  The
       default is $HOME/.mcwd.	The file is created if it does not exist and a msdosdirectory is specified.

       DOS pathnames that contain the '/' or '' separator are supported.  If you use the '' separator or wildcards, you must enclose file  names
       in quotes to protect them from the shell.

       The  mcd command supports the use of to move back one directory in the tree, however, multiple relative moves such as are not supported and
       do not affect your current position in the directory tree.

NOTES

       At logout time, it is advisable to remove old files.

EXIT STATUS

       The following exit values are returned: Success.  Failure.

ENVIRONMENT VARIABLES

       The following environment variables affect the execution of mcd: If set, this variable names the file that contains the name of the current
       mtools working directory as established by the mcd command.  If this variable is not set, the file $HOME/.mcwd is used.

FILES

       Contains  the  name  of	the  current mtools working directory as established by the mcd command.  If this file does not exist, the default
       mtools working directory is A:.  Executable file
