Shell Programming and Scripting

Here is my script which gives the below output when I run.First it will display the list of all groups and then ask for enter the group name and after it will ask for contribuotors or users then I will add contribuotirs or users and it will show the list of all users associated with that group but here I want to add one more thing that I want to add user from the command and not to open the actual file in the below format

WSI-contributors = c003714,e032074,c055216,c002215,jason.kramer,c054253,c186183,c149953,e027514,c055216,e032670,e032670 ,esbuser,svnsystemuser,e030809(for.e.g)

output of the script

1)PORTAL-UDP
2)RO
3)SOA
4)SPLASH
5)SSB-SysSrvc
6)TOI
7)UDP-temp
8)WSI
Enter the group name from above list to check associated user's : WSI
Enter the user's access(RW=contributors or RO=users or blank for both) :
WSI-contributors = c003714,e032074,c055216,c002215,jason.kramer,c054253,c186183,c149953,e027514,c055216,e032670,e032670 ,esbuser,svnsystemuser

You cannot change files without opening them. What is you overall objective?

I acheived this target without opening it.My purpose was to give the access to users who wanted an access on svn repository.I achieve it with
the help of sed command and I was able to scuuessfully add the users to the file.

Thanks in advance

Great! It looked like a good sed or awk problem, but ksh or PERL would do, too.
