split rows
Hi I wanted to split rows based on the number of 1's present in 21st field(21st field is 40 length field) so I wrote the below awk code. However, the tool that I am using to invoke the command is not recognising the command. So, could you please help me to translate this command to sed?


Code:
awk '{for ( i=1; i<=40; i++) {  if ( substr($21,i,1) == 1) print $1 $2 i $5 $7  }}'

I am not sure which tool are you using to invoke the command? Can it recognize and translate any other unix commands?

I am not getting any error. the scenario is like this. I am trying to invoke the command from the datastage external filter stage. when I run the command

Code:
awk '{  for (i=1; i<=40; i++) {  print $0 }}'

through datastage It works fine. However, When I add the if condition and multiple fields to be printed it doesnt work. So I thought it would be helpful if I can try it in sed.

if simple awk works and after ading if it doesn't work means it might not be satisfying the condition you gave
