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.

paps

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

       --top-margin=tm
	      Set top margin. Default is 36.

       --left-margin=lm
	      Set left margin. Default is 36.

       --right-margin=rm
	      Set right margin. Default is 36.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
