Chop lines from file 1

[mrn]

I have a file in the following format

a pool
SSC003 03 Available
SSC004 07 Available
b pool
SSC006 89 Available
SSC007 20 Available
---
---
---
---
c pool
SSC009 22 Available
---
---
---

What I need to do is chop out the different pools into seperate files, how would I do this with awk?

file1 =
a pool
SSC003 03 Available
SSC004 07 Available
b pool
SSC006 89 Available
SSC007 20 Available
---
---
---
---

file2 =
You get the idea I'm sure

Mike,

You've confused me about how you want the file split up. This assumes you want all lines from pool a up to pool b in file 1, pool b to pool c in file 2 etc.

{
if ($2=="pool&quot {
if (fn=="&quot close(fn)
fn = $2 $1 # or "file" ++ix
}
print > fn
} CaKiwi

Put it in a file, pool.awk say and enter

awk -f pool.awk your-file CaKiwi

Should this be:

    if (fn!="") close(fn)

Well spotted, dchoulette! I think I got a star under false pretenses! CaKiwi

The script would work fine except on some vesions of awk if you try to open a large number of files you would run out of file handles and get an error. CaKiwi
