Denovo, Stacks: Getting an “ambiguous redirect” error

Question

I tried running the following command

/public/home/WHC_BBT/Softwares/bin/bin/denovo_map.pl --samples $RawData -O $Popmap -o $fullM2n3 -M 2 -n 3 -m 3 -T 15 &> $logfile

This is the error I got

/opt/gridview//pbs/dispatcher/mom_priv/jobs/14923.admin.SC: line 6: $logfile: ambiguous redirect

I need help on how to resolve this.

Thanks.

Answer 1

This most likely means your variable $logfile does not exist.

Answer 2

At a guess, the variable $logfile is not properly defined (i.e. it hasn't been defined at all). What is the output of the following command:

echo "logfile: ${logfile}"
