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 !!
