Different results in different computers

I run SAHMI (extract_microbiome_reads) for the same fastq files in different computer, but I got two different fasta files. THe only differences between the two computer is the grep version. Is there any version requirement for linux grep ?

It is the problem of awk, as my two computers use different awk, one use mawk but another use gawk. By using gawk instead, I got the same file in the two different computers
