Timestamped File

[SpongeBob1]

Hi,

I was just wondering if anybody knows how to write a C Shell script which can seperate a timestamped file into a number of seperate files, based on the timestamp?

Thanks.

Hi,
if the file contains a timestamp on each line and you want to break that file into separate files the easiest way is to build a list of UNIQ dates in the file and then grep each date out of the file into separate files...

like ( assuming the time stamp is the first entry on the line. )

foreach mydate ( `cut -d' ' -f1 myfile | sort | uniq` )
egrep "^$mydate" myfile >! file.$mydate
end

now this doesn't work if the time stamp has spaces in it like

Jan 3 1995

because the above would put all the lines with Jan into a file. If you change the cut to

cut -d' ' -f1-3

the grep will think Jan 3 and 1995 are 3 separate dates and grep for them all. It is better if the dates are like..... 19950103

because those will Grep and sort much easier.

Hope this helps.
