Print Error with set command
I need to print some mandatory instructions if something fails in the script. I am using set -e to check and exit the script if some scripts/commands return non zero exit code. Is there any way to print these instructions with set command??

scsi_satl

SCSI_SATL(8)							     SG3_UTILS							      SCSI_SATL(8)

NAME

       scsi_satl - check SCSI to ATA Translation (SAT) device support

SYNOPSIS

       scsi_satl [--help] [--log] [--quiet] [--verbose] DEVICE

DESCRIPTION

       This  Bourne shell script calls several SCSI commands on the given DEVICE that is assumed to be an ATA device behind a SCSI to ATA Transla-
       tion (SAT) layer (SATL). The results of each test and a pass/fail count are output.

OPTIONS

       Arguments to long options are mandatory for short options as well.

       -h, --help
	      print out the usage message then exit.

       -L, --log
	      the output to stderr (from each SCSI command executed) is appended to a file called 'scsi_satl.err' in the  current  working  direc-
	      tory.

       -q, --quiet
	      the amount of output is reduced and typically only the pass/fail count is output.

       -v, --verbose
	      increase level or verbosity.

EXIT STATUS

       The  exit  status  of  this script is the number of "bad" errors found.	So an exit status of 0 means all mandatory SCSI commands worked as
       expected.
