Description

Splitting a sieve file in PRP-LLR format into a number of seperate files using awk.

Needed software

  • ASCII editor
  • awk.exe

Example

Split the sieve file t16_b999.prp into 4 separate files.

Preparation WIN

  • copy gawk.exe in a folder
  • create a file named split.awk with this code:
BEGIN{getline line; i=1}
 {if (head[i] == 0)
  {print line >>i".pfgw"
    head[i]=1
  }
  print $0 >>i".pfgw"
  i++
  if (i==5) i=1
 }
  • copy the sieve file in this folder (for example t16_b999.prp
  • calling gawk -f split.awk t16_b999.prp

Results:

  • creates 4 files 1.pfgw to 4.pfgw with equally splitted candidates sorted by n
