Hello
I work with X12 EDI files and many times need to extract entire sets based on the sender ID
Is there a way to do a find on sender ID 01*xxxxxxxxxx
and then extract all data between and including the ISA/IEA

thanks so much

Probably...but you don't post any sample input data, or tell us exactly what you want for output. And we don't know what version/distro of Linux you're using, or ANY details (file sizes, how often to run this, etc.) Hard to answer a question without details.

here is a sample file. There would be multiple files together but I need to do a find on ZZ*xxxxxxx and then print out in same format the lines beginning with ISA and ending in IEA that contain the initial string. I would then reprocess those files through our system. I am looking for a script that I could run .
ISA*00* *00* *ZZ*xxxxxxx *01*001317452L *131016*0634*X*0200 *000030794*
0*P*;
GS*CG*xxxx*OC*131016*0634*30794*X*003030
ST*990*307940001
B1*xxxx*751407xxxx**A

You've posted sample data that doesn't contain what you're looking for??? The only string that has ZZ..... in it is above, but doesn't terminate with IEA. Again, can you post a sample of what you're actually looking for, and a sample of what you want to get OUT? There were several other questions in my first reply which you haven't answered either. Again, without details, there's not much we can help with.

A short hint would be to run the input file through grep for "ZZ*", which will pull out all the lines with ZZ* in them. From there, your script could read that input file, to see if the beginning/ending is what you're after. Can you also post what you've written/tried so far?
