Currently, Abricate will exit successfully regardless of the exit code of the BLAST command. This is misleading as failures in the BLAST command (eg. if it is killed by the OOM killer) will emit the message "Found 0 genes in <file>", rather than indicating an error has ocurred. This change checks the exit code of the executed command after close is called. If it is non-zero, Abricate will terminate with a brief message and the same exit code; allowing the calling shell to decide what to do with the error. This change uses a bash subshell instead of sh to make use of pipefail. For anyone who wants to continue using sh I wave my hands in the air and leave it as an exercise to anyone who wishes to inspect the exit code of each piped command instead.
