split files by specifying a string (bash shell)

Shell Programming and Scripting
1

Hi all,

I have a file of around 300 lines in which string "SERVER" occurs around 32 times.

for eg.

I need to split files like, for eg

I am using this code
awk '/SERVER/{n++}{print > f n}' f=/vikas/list /vikas/final

But the problem is that it makes maximum of 10 files, but I need more than 30.
I have tried using nawk, but didnt worked.
I am using bash scripting on Sun OS.

Any other way of splitting this data ???

Pls help !!!

Thanks in adv.
Regards,
Vikas

hi,
this cmd is making as many blank files as the string SERVER is there in the final file. :frowning:

pls help

5 
awk '/SERVER/{if (n) close(output); output= f ++n} n {print >> output }' f=/vikas/list /vikas/final

Sorry 'bout that - some awk's increment pre-increment ops don't seem to work the way they supposed to.

awk '/SERVER/{if (n++) close(output); output= f n} n {print >> output }' f=/vikas/list /vikas/final

On Solaris - use 'nawk' or '/usr/xpg4/bin/awk'

9 
nawk '/^SERVER/ { 
	close(f); f = "/vikas/list" ++c 
	} 
{ 
	print > f 
}' /vikas/final

hello friend,

this command is only making two files list1 & list2.

Thanks.

Hi,

I tried lots of commands including the above ones. They all run fine on Linux machines
BUT not on the solaris machines, dont know the reason behind it.

Anyways, MANY MANY THANKS to all for your time and help. I found this command to work perfectly.

/usr/xpg4/bin/awk '/SERVER/{n++}{print > f n}' f=/vikas/list /vikas/final

Thanks again.
