UNIX for Dummies Questions & Answers

Hi,

I am receving a file from remote site which has EDI information for 830, 862 and 997 and I want to extect the data for 997 using grep's or any other methods.

The data look like this:

ISA~000
0000-0001-1000~997
AK1000~m
000~IEA~M

ISA~000
0000-0001-1000~849
000~IEA~M

ISA~000
0000-0001-1000~862
000~IEA~M

What I want to do is just extract the portion starting from ISA containing 997 upto the next line where it has "000~IEA~M" i.e. where it ends and not the info for 849 and 862 and redirect the output to some file. I am sure there must be some easy way to do it. In the file there are no spaces between data. I am just adding the spaces to make it more readable.

TIA,
Inder

nawk -f is.awk myFile.txt

is.awk:

Code:

BEGIN {
  FS=RS=""
  PAT="~997$"
}
{
  for(i=1; i <= NF; i++)
    if ( match( $i, PAT )) {
      print
      next
    }
}

Hi vergse99,

Thanks for the reply!!!

When I am trying to run the script. I am getting this error message:

I checked for nawk and we hdon't have that installed.

dilbert:/UTIL/EDI/DATA/inbound/recent/inder>awk -f is.awk ame29454.0511190545
awk: Input line ISA~00~ ~00 cannot be longer than 3,000 bytes.
The source line number is 3.

do you have 'gawk'?

yes, I do have gawk. I tried running it with using gawk but that did not work. I think it's my fault. I did not explain to you data correctly.
That's how the data looks like:

There is no separation between the data ot atleast it does not look like. It starts with "ISA" and then has either 997 or 862 in the data and then it has IEA at about the end and some text after that and again starts with ISA.

I know, I am trying to say so many things at the same time. Please let me know if I can explain in a better way or send it to you directly.

Do you have perl? If so, what version? (do: /path/to/perl -v ).

/path/to may be /usr/bin or /usr/local/bin
