shell script for reading of configuration files


Hello.
I write a shell scripr reading of configuration files. I need to read data from config file. Here is the shell command for extracting the file.

cat renicepid.conf | gawk -F : '/./ {print $2}'

I have this file:
renicepid.conf
//--------------------------------------
Application: -r 2 xterm terminal asdfgh

I need to extract the data after Application:.So, now this work but my question is how to do that if there are many such lines.
Something like this:
//----------------------------------
Application: -r 2 xterm terminal asdfgh
Application: -r 2 aaa dddd ggggg
Application: -r 2 aaa dddd ggggg
Application: -r 2 rrr tt fdgfd dfgsdfgdfg

In that shell command i extract all found lines. I need to have an access to every line.

Thanks in advance.

Code:
cat renicepid.conf | gawk -F : '/./ {print $2}' | while read line; do echo "DO SOMETHING: $line"; done
Just replace echo "DO SOMETHING: $line" with whatever you want to execute for each line.

read reads a single line from stdin and stores it in the specified environment variable.

The while loop will simply execute until read returns an error (when no lines remain to be read).
