Searching the pattern and accordingly changing the contents using shell
Actually I have one sheel script where I am asking user to enter option 1) for adding 2) deleting, so now on the basis of provided input I have to update file accordingly.

---------- Post updated at 11:28 PM ---------- Previous update was at 11:24 PM ----------

Code:
[root@lab vishal]# echo $tmp
admins = anand,ameo,satheesha,user1,user2,user3,user4,user5,user6,user7,user8,user9,user10,vishal
[root@lab vishal]# echo $tmp1
admins = anand,ameo,satheesha,user1,user2,user3,user4,user5,user6,user7,user8,user9,user10,vishal,rohit

But when I try to replace $tmp with $tmp1 in file1, still it didn't replaced and ",rohit" not added.

Code:
[root@lab vishal]# sed 's/$tmp/$tmp1/g' file1
[groups]
admins = broadhop,anand,ameo,satheesha,user1,user2,user3,user4,user5,user6,user7,user8,user9,user10,vishal
nonadmins = read-only
[/]
@admins = rw
@nonadmins = r
