Description
Splitting a sieve file in PRP-LLR format into a number of separate 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.exein a folder - create a file named
split.awkwith 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.pfgwto4.pfgwwith equally splitted candidates sorted by n
