awk : split file and rename and save in path according to content

Hello,

I'm using Windows 7 ; sed, awk and gnuwin32 are installed.
I have a big text file I need to manipulate.
In short, I will have to split it in thousands of short files, then rename and save in a folder which name is based upon filename.

Here is a snippet of my big input.txt file (this pattern is repeated 70k times) :

ctime=1041379201
version=text text
name=Bob.2111
targets=text text
title=text text
description=long text ending with[[#source_]]

As of now, I know how to split it with awk :

awk "/ctime/{x="F"++i;}{print > x;}" input.txt 

Yet I dont know how to drive awk in renaming files.
In every splitted file, there is a line (line number 3 of the splitted file) which says the name of the expected file. In showed snippet, it is : name=Bob.2111 .
I expect to have about 70k files named like Bob.[0-9]+ (no extension).

My question number one is : is awk able to do that ? is awk able to catch a value in current file according to some pattern for renaming the splitted files ? I did not find anwser yet. Most examples order awk to use a name which doesnt come from the manipulated file.

My question number two is : is awk also able to save the splitted files in a constructed path, according to content ?
I want all splitted files containing Bob.1[0-9]+ to be saved in folder 1/ ; all Bob.2[0-9]+ to be saved in folder 2/, etc., for limiting the quantity of files per folder (using first number of numerical id).

I guess I need to catch every Bob.[0-9]+ in a variable $1.
Thus I may use this variable for (1) renaming files and (2) for moving files
If Bob.2111 is $1, I would like to save file like that {substring $1,4,20}/$1 which would give 2/Bob.2111 .

As you can guess, I'm not expert
Thank you.

I'm not sure I grasped everything that you specified...
Why rename when you can save it immediately to the desired file? This requires all the directories exist:

awk '/ctime/ {T1=$0; next} /version/ {T2=$0; next} /name/ {FN=substr ($2, 5, 1) "/" $2;  print T1 > FN; print T2 > FN} {print > FN}' FS="=" file

Maybe I'm not clear, I'm sorry.

Big input file is full of text, structured like that :

ctime=1041379201
name=Bob.2112
targets=text
title=text
description=text
text=text ending with [[#source_]]
ctime=1041379201
name=Bob.2113
targets=text
title=text
description=text
text=text ending with[[#source_]]
ctime=1041379201
name=Bob.2115
targets=text
title=text
description=text
text=text ending with[[#source_]]
ctime=1041379201
name=Bob.2116
targets=text
title=text
description=text
text=text ending with [[#source_]]

I need to split this big file in short files, from [ctime to ]ctime.
Which I can do using awk.

I'm looking for a way to tell awk (or else ?) how to name these splitted files. I wish it is doable with awk during the splitting step (split and give name).
I want files to be named depending to their content : Bob.2112, Bob.2115, Bob.2116, etc.

If we imagine the big input text has this form :
a=aa
b=bb
c=cc
d=dd
a=aa2
b=bb2
c=cc2
and value wanted is after c=, might it help for building the command ?

@Rudi : I'm trying to play with your code (on Windows, sorry), with no success atm : awk: (FILENAME=input.txt FNR=2) fatal : can't redirect to `/' (Permission denied)

after you have split the files,,,in the same directory

for file in F*
do
$name=$(awk -F"=" '$1=="name"{print $2}' )
cp $file $name
done

if this works , change cp to mv

This is the result for me:

find 2
2
2/Bob.2113
2/Bob.2115
2/Bob.2112
2/Bob.2116
2/Bob.2111

Print the internal, new file name to stdout for debugging purposes.
And, why do you change the input file structure between posts?

To be able to handle maaany files, you might want to close (FN) just before you define the new one...
