Separate a portion of text file into another file - Shell Programming and Scripting

Hi,

I have my input as follows :

I have given two entries-

From system Mon Aug 1 23:52:47 2005
Source !100000006!:
Impact !100000005!: High
Status ! 7!: New
Last Name+!100000001!:
First Name+ !100000003!:
Phone !100000004!:
email !100000000!: xyz@abc.com

email !100000000!: pqr@abc.com

Script was unable to complete due to

The above is like a template and it would repeating in my input file and the would be also be updated with new entries from time to time.

What I want to do is for each entry I want to extract the email id and mail the content to that email id.

So what I thought is that if I could get each entry into a temporary file, then I could extract the email id from that and use mailx to send the mail.
But how should I go about separating the entries is the big problem.
Please Help.
Any other approaches to the problem are also welcome.

Thanks in advance,
srikanth

something along these lines - not tested.

nawk -f sri.awk myInputFile

sri.awk:

Code:

BEGIN {
  FS=RS=""
}
{
  for(i=1; i <= NF; i++)
    if( match($i, "^email.*!:") ) {
       addr=substr($i, RSTART+RLENGTH+1)
       break;
    }
    printf("addr->[%s]\n", addr)
    cmd= "mailx " addr
    print | cmd
    close(cmd)
}

Thanks Vgersh,

But it did not work. This was the output which I got when I ran it with my input.

addr->[]
No mail for fe598
addr->[]
No mail for fe598
addr->[]
No mail for fe598
addr->[]
No mail for fe598
addr->[]
No mail for fe598
addr->[]
No mail for fe598

Regards,
srikanth.

here's the output I get based on the sample input file you've provided:

Code:

nawk -f sri.awk sample.txt 
addr->[xyz@abc.com]
addr->[pqr@abc.com]

Validate your real file jives with what you've posted originally.
