Error Need help with looping through file contents
Hi,

I have a several files with ".out" extension in a folder and each file has the below like contents
Code:
....
appname: wonder1
.....
logname78.log
logname88.log
.....
CAP: 2
.....
appname: wonder54
......
logname28.log
logname58.log
logname54.log
.....
CAP: 3
.....
appname: wonder11
.....
logname92.log
.....
CAP: 1
.....

Where "...." can be bla bla bla any string.
Below is the desired output
Code:
wonder1


wonder54



wonder11


logname78.log
logname88.log

logname28.log
logname58.log
logname54.log

logname92.log

I run a for loop to traverse through the folder picking one file at a time.

Code:
for file in *.out
do
        for csfile in $(grep -F 'appname' $file | awk '{print $2}')
        do
                echo $csfile
                for counter in $(grep -F 'CAP:' $file | awk '{print $2}')
                do
                        let start=1
                        for i in {$start..$counter}
                        do
                                echo " "
                        done
                done
        done
        for logg in $(grep -F '.log' $file)
        do
             echo $logg
        done
     
echo " "
done

The above effort does not yield what i desire ...

Problem 1: The value of CAP remains always the same i.e the first vaue in the file.

Problem 2: The .log files are not seperated by blank lines as seen in the desired output.

Current output looks something like this

Code:
wonder1


wonder54


wonder11


logname78.log
logname88.log
logname28.log
logname58.log
logname54.log
logname92.log

I know the basics of loops but can u help me structure my code get the correct output.
