Hi.

Addressing the splitting of the file with standard utility csplit:
Code:
#!/usr/bin/env bash

# @(#) s1	Demonstrate splitting of file at /pattern/+-count, csplit.

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C csplit

FILE=${1-data1}

# Remove debris from previous runs.
rm -f xx??

pl " Input data file $FILE:"
cat $FILE

pl " Current situation of resultant xx?? files (expecting none):"
ls xx??

pl " Results, counts of split file in characters:"
csplit -k -z $FILE '/Version/-1' '{*}'

pl " Current situation, and content of files:"
ls -lgG xx??
pe
head xx??

exit 0

producing:
Code:
$ ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian GNU/Linux 5.0.8 (lenny) 
bash GNU bash 3.2.39
csplit (GNU coreutils) 6.10

-----
 Input data file data1:
Unrelated stuff
Version something
No discernible pattern
Version otherwise

-----
 Current situation of resultant xx?? files (expecting none):
ls: cannot access xx??: No such file or directory

-----
 Results, counts of split file in characters:
34
41

-----
 Current situation, and content of files:
-rw-r--r-- 1 34 Sep 12 06:33 xx00
-rw-r--r-- 1 41 Sep 12 06:33 xx01

==> xx00 <==
Unrelated stuff
Version something

==> xx01 <==
No discernible pattern
Version otherwise

See man pages for details.
