Are you proved this code?

I don't know why, but in the POLITICS, my regexp doesn't work, the code don't show me the politics.

Maybe the problem is because i'm using awk, not nawk?

I found it did not work either, but I will leave you to figure out why. It is in the right place though, you just need to get the syntax right.I suggest cutting the expression right back to basics as it probably does not need to be that complex now that the range I defined is getting you into the right area of the file.Good luck

I can't cut the expression, i need the maximum complexity in the expression, because the user can write fine the first part of the expression and bad the second part, and the expression mustn't match.

And i don't know why the expression doesn't works, because y have this expression out of ranges and it works.

I see problems with spaces and tabs.

Thanks!

I mean break the regular expression down into 3 seperate expressions, one for each line and build each slowly: -

Code:
/POLITICS{/,/}/ {
    if ( $0 ~ /POLITICS{/ ){
        printf("%s\n", "for POLITICS:")
        next
    }
    if( $0 ~ /}/)
        next
    print
  
    if ( $0 ~ /^[0-9]+[%]+[MKGCF]+[\t]+/){
        ## 65%F    mpg     =000M   02/02/02/05/05M
        print "Instructions for 65%"
    }
}

So you end up with three if statements each with a smaller expression, one for each line.

OP for above: -

Code:
for POLITICS:
100MF   doc,docx,xls    <5600K  02/04/02/02/02K
55MF    jpg     >300M   03/03/02/03/05K
65%F mpg =000M 02/02/02/05/05M
Instructions for 65%

Always break the work down into manageable pieces
