Large file splitting into smaller files

Here ya go

I've requested that this question be deleted for the following reason:

Wrong Question.

Assuming that the first column of your file contains a datestamp (not timestamp!) without embedded spaces:

awk '{print $0 > $1".out"}' inputfile

awk '{print $0 > $1".out"}' verbosegc.20120911.170447.37451.txt.001
awk: (FILENAME=verbosegc.20120911.170447.37451.txt.001 FNR=14) fatal: can't redirect to `</initialized>.out' (No such file or directory)

Getting this error.

<af type="nursery" id="1" timestamp="Sep 11 17:04:52 2012" intervalms="0.000">.

Based on the above line , need to separate files for Sep11, 12, 13 & 14.

Have these timestamps in randomly.

<af type="nursery" id="1" timestamp="Sep 11 17:04:52 2012" intervalms="0.000">
<af type="nursery" id="193" timestamp="Sep 12 00:00:03 2012" intervalms="1370951.683">
<af type="nursery" id="491" timestamp="Sep 13 00:00:05 2012" intervalms="802938.834">
<af type="nursery" id="757" timestamp="Sep 14 00:02:49 2012" intervalms="1115834.953">

Need to Separate the files based on the starting time of the day.

You are the  Master . It  worked  great.

Thx for the points!

You're fast - I eventually planned to enhance the command so that the output filenames would contain the input filename:

awk -F"timestamp=\""  '{D=substr($2,1,6); gsub(" ","",D); print $0 > FILENAME "-" D ".out"}' inputfile

Better?

After each timestamp line I have some data to be  get copied in the file. Its not getting copying in the new files created.

So not every line contains "timestamp"? Didn't know that.

Anyway, here you go:

awk -F"timestamp=\""  'BEGIN {D="NODATE"} {if($0~"timestamp") {D=substr($2,1,6); gsub(" ","",D)}; print $0 > FILENAME "-" D ".out"}' inputfile

Should the first line of inputfile not contain "timestamp" then this line (and all following lines up to, but not including, the first line containing "timestamp") will go to a file named "inputfile-NODATE.out"

thank you very much WoolMilkPorc. It worked with out issues.
