Shell Programming and Scripting

looking at your example, you could use sed to do the pattern match and pipe it to split

Code:

sed -n /^D/p file | split -l2

Hi Rajamadhavan,

This works cool. Just few confirmation required.

I guess the ^ is escape character, Am i right?
Secondly, the split command is creating the files with names xaa,xab and so on.
I want to give specific name and i tried giving the below command:

Code:

sed -n /^D/p file | split -l 2 -d test

This fails saying that, "test" does not exist. Where in i want to create file names as test01,test02 and so on.

Can you suggest where to mention the spit file name.

Thanks,
Ajay

^ is the regex indicating the beginning of the line.

This will change the prefix from 'x' to 'test'. As far as I know, you can only change the prefix and not the suffix. So the split files will be testaa, testab and so on

Code:

sed -n /^D/p file | split -l2 - test

Thanks ton Rajamadhavan

It worked. And we are also able to change the suffix also:

Code:

sed -n /^$a/p file | split -l 2 -d - test

And my output is test00, test01 and so on.

Thanks again for ur help.

Thanks,
Ajay

Ok. -d option is not available on split on my system.
