Nawk help!!!
Hi,
Please help me I want to filter all messages having a value less than a particular value..Please advice how to use <= in the below red marked script..

Getting the error as no such file or directory for the marked line no.

Thanks in advance...

Script is as under :
Code:
read message
gawk -v search<="$message" '
    /No/,/=/ { 
       block = (block ? block ORS : "") $0;
    }
    /=/ { 
       if (block ~ search) 
          print block;
       block = " ";
    } ' myfile

Let me guess.

Code:
read message
gawk -v search=$message '
    /No/,/=/ { 
       block = (block ? block ORS : "") $0;
    }
    /=/ { 
       if (block ~ search) 
          print block;
       block = " ";
    } ' myfile

    }
    /=/ { 
       if (block ~ search) 
          print block;
       block = " ";
    } ' myfile

This is already working but I want to filter out having the value less than or equal to the input "message"

Input file :

==========================================================
Code:
[No.            ] 7
[TimeStamp      ] 2010-10-30 11:45:39
[SIO            ] >ISUP
[NI             ] NAT
[Ticks          ] 10

==========================================================
Code:
[No.            ] 2
[TimeStamp      ] 2010-10-30 11:45:38
[SIO            ] >ISUP
[NI             ] NAT
[Ticks          ] 24

==========================================================

Suppose the value of input "message" is 2 then it should include the block having the [No. ] 2 and not [No. ] 7

Output file :, for message = 2

==========================================================
Code:
[No.            ] 2
[TimeStamp      ] 2010-10-30 11:45:38
[SIO            ] >ISUP
[NI             ] NAT
[Ticks          ] 24

==========================================================

If your records are separated by the ============= lines, than this should work:
Code:
awk '/No/&&$3<=m' RS== m=$message file

otherwise, try this:
Code:
awk '/No/,/Ticks/{if(/No/&&$3<=m)p=1;if(p)print;next}{p=0}' m=$message file
