problem in using sed command in editing a file
Hi all,

I have a conf file, i want to update some entries in that conf file. Below is the code for that using a temporary file.

Code:
sed '/workgroup=/ c\workgroup=Workgroup' /usr/local/netx.conf > /usr/local/netx.conf.tmp
mv -f /usr/local/netx.conf.tmp /usr/local/netx.conf

Sample contents of netx.conf :-
Code:
workgroup=Workgroup
Use=hosts
security=user1
....
...

I do not want a .tmp file ,please let me how can i update an entry in a file without using a temp file.
Is it possible using awk ??????
Thanks all !!

sensors(1)							Linux User's Manual							sensors(1)

NAME

       sensors - printing sensors information

SYNOPSIS

       sensors [ options ] [ chips ]

DESCRIPTION

       sensors is used to show the current readings of all sensor chips, and to set all limits as specified in the configuration file.

       sensors	knows  about  certain  chips,  and  outputs nicely formatted readings for them; but it can also display the information of unknown
       chips, as long as libsensors knows about them.

OPTIONS

       -c config-file
	      Specify a configuration file. If no file is specified, the name `sensors.conf' is used. If the name does	not  contain  a  directory
	      slash,  or  this parameter is not present, the following path is examined: /etc, /usr/lib/sensors, /usr/local/lib/sensors, /usr/lib,
	      /usr/local/lib, .

       -h     Prints a help text

       -s     Evaluates all `set' statements in the configuration file. You must probably be `root' to do this. If this parameter  is  not  speci-
	      fied, no `set' statement is evaluated.

       -A     Do not show adapter and algorithm for each chipset.

       -u     Treats all chips as unknown ones. Output will be of much lower quality; this option is only added for testing purposes.

       -v     Returns the program version.

       -f     Prints the temperatures in degrees Fahrenheit instead of Celsius.

FILES

       /etc/sensors.conf
	      The system wide configuration file. See sensors.conf(5) for further details.
