I need to examine a huge CDR file according to a complex (at least for me) condition like below and i couldnt write anything
In CDR file there are more than hundreds of fields, I need to print the rows which matches the below condition:
while $13 field of subsequent CDRs are equal to eachother and when $NF == 202 ||500 then check if $3 of the lines and decide which of those $3 fields are smaller or bigger and sort it from smaller to bigger, data:
because above two rows has same $3 (gsm no) and $NF of them are 202 and 500 in turn (it could be opposite too ; 500 and 202) so the smaller of 3rd fields comes first in output..
1) only records that should be printed are the ones with matching field 13. If a record has no match it isn't printed.
2) matching records would be consecutive in the input.
awk -F \| '
function print_set( i )
{
if( iidx < 2) # print only if there were more than 1
return;
asort( idx3 );
for( i = 1; i <= length( idx3 ); i++ )
print buf[idx3];
}
!( $NF == 202 || $NF == 500 ) { next; }
p13 != $13 { # not the same; print previous set if there
print_set( );
iidx = 0; # reset cache
delete idx;
delete buf;
}
{ # cache information untl we have a $13 that does not match
p13 = $13;
idx3[iidx++] = $3;
buf[$3] = $0;
}
END {
print_set( );
}
' input-file >output-file
If all 202/500 records are to be printed, regardless of whether or not there was a matching record based on field 13, then comment out the first two lines (if and return) in the print_set function.
Scrutinizer if the fields "500" and "202" wouldnt be consequtive in CDR files then would it be so diffucult to reach the same output? I guess it would be a long process to check 500 or 202 fields of same gsm_no in same file as there would be tousands of CDR rows in a file and the desired rows could come several hundred rows after the other one) corrcect?
Can always count on you for the absolute smallest programme!
Bloody asort(); It's what I get for assuming gawk. I'd post something with a simple sort in it, but it's still not as short and sweet, nor needed given your code, so I'll let it ride.
