Im trying to write an if-else loop that does the following

grep -c ^">" <file>

If results of grep are >0, move file to location1 Else move file to location 2

So far i have:

def numfasta = grep -c ^'>' {input} if [[ $numfasta -gt 0 ]] ; then mv {input} {output.denoise} else mv {input} {output.rerep} fi

but this is not working

Thanks
