Regarding Background process.

Hi

I have a file in unix which has got around 5million records

when i do the cat on the file, it is going to list all the 5m records

but what i wanted to do is, after listing the 25,000 records, the command should run in the background.

which means, as soon as the listing of record reaches more than 25k , this command shud be put in background until it reaches end of record

can any one plz help me out with the unix sytax/command that does this.

What is the context?
Why do you want to do this?
What are you trying to accomplish?
(There may be an easier way to attain your goal.)

Would using less rather than cat be of any help?

If you're not doing anything with the records you can use head:

Code:

head --lines=25000 /var/log/messages

Otherwise archtoad6 is right, more info is needed...

BTW, that can be simplified to:

Code:

head -25000 <filename>

And please, the add'l info . . .
