if $LOGIN found in file then execute X - help!

I'm trying to do specific actions based on whether a string is contained within a file or not. More specifically, I'm using the $LOGIN variable to compare to a user_list plain text file to determine what auto login process to execute for the specific user.

I've seen several posts using the following format to determine if a string is contained within the specific file name, but I'm having issues putting this into a conditional loop to execute the different login processes.

find . -name 'user_list.txt' -exec grep -ilw "$LOGIN" {} \;
This outputs the filename when the $LOGIN is contained and outputs nothing if it isn't, but I can't figure out a way to use this info.

Any input or ideas would be greatly appreciated. Smilie

LOGIN.ACCESS(5) 					      BSD File Formats Manual						   LOGIN.ACCESS(5)

login.access -- login access control table DESCRIPTION
The login.access file specifies on which ttys or from which hosts certain users are allowed to login. At login, the /etc/login.access file is checked for the first entry that matches a specific user/host or user/tty combination. That entry can either allow or deny login access to that user. Each entry have three fields separated by colon: o The first field indicates the permission given if the entry matches. It can be either ``+'' (allow access) or ``-'' (deny access) . o The second field is a comma separated list of users or groups for which the current entry applies. NIS netgroups can used (if configured) if preceeded by @. The magic string ALL matches all users. A group will match if the user is a member of that group, or it is the user's primary group. o The third field is a list of ttys, or network names. A network name can be either a hostname, a domain (indicated by a starting period), or a netgroup. As with the user list, ALL matches anything. LOCAL matches a string not containing a period. If the string EXCEPT is found in either the user or from list, the rest of the list are exceptions to the list before EXCEPT. BUGS
If there's a user and a group with the same name, there is no way to make the group match if the user also matches. SEE ALSO
