BASH (grep / sed / awk): find string within a (line) range

I have this kind of akward string search.

Lets say I have this text file called "test.cnf":

Code:

[client]

port mysql    = 1234

port ftp      = 1235

etc...



[server]

port mysql    = 1234

port ftp      = 1235

etc...

I want to find the line number of "port mysql = 1234" under [client] and not under [server]

What it means is, I have to search only beneath [client] but not beneath [server].
There are 2 tabs between "port mysql" and "= 1234"

Both [client] and [server] parts are in one text file.

THANKS!

Code:

sed -n '/\[server\]/,/^$/{ /port mysql/p }' test.cnf

The /\[server\]/,/^$/ selects the [server] section. The commands inside { .. } are only executed inside this range. You could have more than one command or even select a subrange if need be.

The mysql config files use a blank line between sections, which allows you to easily end select the end of the range.

Thanks [edit: also for the VERY fast response!!!] it worked!!!!!!!!!!!!!!!!!!!!
