I have a file that I need to parse multiple sections from the file.

The file contains multiple lines that start with ST (Abunch of data)
Then the file contains multiple lines that start with SE (Abunch of data)

SE*30*0001
ST*810*0002

I need all of the lines between and including these.
They are invoices.
The invoice starts with the ST line and ends with the SE line.

I need to break out all of the invoices into separate files.

Can someone please help me. I know Grep, sed, or AWK can do this, but not sure how.
Thank you


Here is an example:

Thank you for your prompt response.

It did what I wanted. However the three sections need to be parsed to to different files.

So you have
ST
data
SE
This should be taken to file 1
ST
data
SE
This should be taken to file 2

ETC.....

Also I noticed that the ST and SE are numbered.

ST*810*0004
Then
SE*(Number)*0004
Thank you

nawk 'BEGIN{n=1}
$0 ~ /^ST/ {f=1}
$0 ~ /^SE/ {invoice[n]=sprintf("%s\n%s",invoice[n],$0);f=0;n=n+1}
{
if (f==1)
invoice[n]=sprintf("%s\n%s",invoice[n],$0)
}
END{
for (i in invoice)
print invoice[i] >> i
close(i)
}' filename

Hi.

An alternate awk solution:
Producing:
Choose the base file name you wish in variable "name" ... cheers, drl

#-- Use ST values as output filename.
awk -v out="/dev/null" '
/^ST/ {gsub("\\*","-",$0); out=$0".txt"}
/^SE/ { close(out) }
{ printf "%s\n",$0 >> out }
' $INFILE

Output will be
ST-810-0001.txt
so on ...

I wanted to thank all of you for your response.

One issue, I am porting the awk utility to windows. So I do not think all of the functionality is there.
For instance when I used Ramesh's example, I received numerous errors.
Here is the code:

c:\tools\gnuwin32\bin\awk -v '/^ST/ {gsub("\\*","-",$0); out=$0".txt"}
/^SE/ { close(out) }
{ printf "%s\n",$0 >> out }
' %input%edifile.dat

Here is the result:
