Split large file into smaller files without disturbing the entry chunks
Dears,
Need you help with the below file manipulation. I want to split the file into 8 smaller files but without cutting/disturbing the entries (meaning every small file should start with a entry and end with an empty line). It will be helpful if you can provide a one liner command for this and also help me understand the command u give. I'm not very good at this.
Input_file:- (With more than 10 Million such chunks separated by empty line)
small_file1:- small_file2:-
Thank you in advance.

pfc
PFC(1) General Commands Manual PFC(1)NAME
pfc - active precompiled filters generator
SYNOPSIS
pfc <expression> >/etc/ppp/your.active.filter
DESCRIPTION
This manual page documents briefly the pfc command.
pfc is the Precompiled Filter Compiler - a tool to generate "active precompiled filters". If your pppd supports this feature, you can use
this utility to generate the filter files. The Active Filter allows a connect on demand pppd to determine what is 'interesting' traffic,
and then initiate the PPP session. The tool allows you to create the filters, in libpcap format, for use by pppd. Common filters are used
to ignore traffic (ie: ntp, various protocol keepalives, etc...) so PPP sessions are not initiated until 'real' traffic requires them.
Note that the generated compiled filter expression is specific to point-to-point links, and differs from the format generated by tcpdump
-ddd.
(specify precompiled-active-filter=/etc/ppp/your.active.filter in the ppp options file)
EXAMPLE
/usr/bin/pfc ntp and ldap > /etc/ppp/your.active.filter
SEE ALSO
pfc is from the FLoppy Isdn 4 Linux project - see http://www.fli4l.de/en/home/news/
