Shell Programming and Scripting

Change the script like this:

Code:

#! /usr/bin/nawk -f

BEGIN {
  FS = OFS = "\57"
  }
NR == FNR {
  t = $NF; sub(/\/[^\/]*$/, "")
 _[$0] = t; next
 }
{
  t = $NF; sub(/\/[^\/]*$/, "")
  if ($0 in _ && _[$0] > t)
    print $0, t
}

And run like this (notice the order of the input files):

Code:

./script.awk set2 set1

I ran like the below. But no output at all.

Does the code needs any change? something related to cmd line arguments????
Ok can we modfiy it as follows:

Set 1 and Set2 are got from the o/p of some command.

Try swapping the input files.

Seems its working. But still i'll paste what is needed

/home/odyssey/f091018>cat set1
/vobs/odyssey/sm/sybase/ddl/ods/SM_CFSCASHFLOWONHOLD.trg@@/main/3
/vobs/odyssey/sm/sybase/ddl/ods/SM_CFSCASHFLOW.trg@@/main/3
/vobs/odyssey/sm/sybase/ddl/ods/SM_CFSDIARY.trg@@/main/4
/vobs/odyssey/sm/sybase/ddl/ods/SM_SMVALIDCASHFLOW.trg@@/main/5


/home/odyssey/f091018>cat set2

/vobs/odyssey/sm/sybase/ddl/ods/SM_CFSCASHFLOWONHOLD.trg@@/main/13
/vobs/odyssey/sm/sybase/ddl/ods/SM_CFSCASHFLOW.trg@@/main/23
/vobs/odyssey/sm/sybase/ddl/ods/SM_CFSDIARY.trg@@/main/4
/vobs/odyssey/sm/sybase/ddl/ods/SM_SMVALIDCASHFLOW.trg@@/main/15

The requirement is all the files in Set 1 should have last field bigger than the same file in set 2 (if present .. ). If set2 version is higher than we want to list that file name in the o/p from set 1.




But will the usage remains the same? i.e ./script.awk set2 set1 ????

The script should be OK.
Yes, same usage.

Thanks Alot. I appreciate your help.


Can we modify the script a bit.

say
I'll be using following two lines inside the script itself. So set1 and set2 will populate inside awk script file only.


cleartool find . -version "lbtype($label1)" -print > /tmp/set1

cleartool find . -version "lbtype($label2)" -print > /tmp/set2

Now how can we use set1 and set2 inside the script itself and not as external arguments??????

what are the changes required in this case?????

You may try this quick and dirty solution (you should use bash or /usr/dt/bin/dtksh for this script):

Code:

#! /bin/bash

nawk 'BEGIN {
  FS = OFS = "\57"
  }
NR == FNR {
  t = $NF; sub(/\/[^\/]*$/, "")
 _[$0] = t; next
 }
{
  t = $NF; sub(/\/[^\/]*$/, "")
  if ($0 in _ && _[$0] > t)
    print $0, t
}' <(cleartool find . -version "lbtype($label2)" -print) \
   <(cleartool find . -version "lbtype($label1)" -print)

I would write it all in AWK, but I don't have access to cleartool.
