Split one file to many based on pattern
Hello All,

I have records in a file in a pattern A,B,B,B,B,K,A,B,B,K

Is there any command or simple logic I can pull out records into multiple files based on A record? I want output as

File1: A,B,B,B,B,K
File2: A,B,B,K

So you want the first six records in one file, and the last four records in another?

Code:
awk -F, -v OFS="," '{ print $1,$2,$3,$4,$5,$6 > "file1" ; print $7, $8, $9, $10 > "file2" }' inputfile

This will work for the data you've given but might not for your real data if it's much more complicated. A representative sample (obscured where necessary) would be appreciated.

Thank you very much for the reply, I should not be counting number of lines, I have to pick lines based on A record.

Whenever a line starts with 'A', I need to pick all the lines until next 'A' line and write it to file.

This is not apparent from the input and output you have shown. It shows a single line being divided into two different files.

Show the input you have, and show the output you want.

A890345765875
B378945634789
B934785643534

Desired Output:

Why 'file' and not 'file4', or does that matter?

Code:
awk '/^A/ { if(F) close(F); F=sprintf("%s%d", NAME, ++N) } { print > F }' NAME="File" inputfile

Use nawk on solaris.

You could also do file0001, file0002, etc, etc, which sorts more nicely in a directory listing, by putting "%s%04d" in sprintf instead.
