UNIX for Dummies Questions & Answers

Hi everyone,

I need to create a script which dynamically splits Flatfiles and append a date. Only those should be splitted if they have more than a million rows but the date should be append every time.

E.g. in my folder I have 3 flat files and only 1 of them has more than a million rows.

FileX.out
FileY.out
FileZ.out

They should look like this now-->

FileX.out001_ddmmyy
FileX.out002_ddmmyy
FileY.out_ddmmyy
FileZ.out_ddmmyy

Can anyone help me on this?

Thanks in advance
Regards Richard

have a look at split command.

and to get date use

Code:

#  date +%d%m%y
111010

Though it would likely be better to use year-month-day as this will make life easier for sorting later:

#  date +%Y%m%d
20101011

:-)

thank you for your post.

and it works good.

But how does this will look in a ksh? and how can he split and add the date dynamically?

FileX.out
FileY.out
FileZ.out

are always created in this format, and in the end only the new format (prefix 001 002_date) should be visible

Try:

Code:

for i in file*.out
do
  mv "$i" "${i}_$(date +%d%m%y)"
done
