puzzling over check_mailscanner

[Jeff A. Earickson]

Julian,

I was staring at the bin/check_mailscanner script, and I've
got to ask, why are the variables at the top only used some
of the time?  You have:

PATH=/usr/bin:/bin
export PATH
PERL=perl
AWK=awk
GREP=grep
FGREP=fgrep
EGREP=egrep
PGREP=pgrep
PS=ps
UNAME='uname -a'

Then later in the script you use awk, grep, etc in some places
and $AWK, $GREP, etc elsewhere.  Shouldn't this be consistent?
