I put a bunch of "constants" at the top of my scripts:


AWK=/bin/awk
CAT=/bin/cat
GREP=/bin/grep
SCP=/usr/bin/scp
SED=/bin/sed
SSH=/usr/bin/ssh


And then, my commands look like this:


servers=`${CAT} ${file} | ${SED} -e 's/\t/  /g' | ${AWK} '{ print $1 }'`
for i in ${servers}; do

  ${SSH} $i ${GREP} foo ${foofile}
  if [ $? -ne 0 ]; then

    ${SCP} ${foofile} $i:${foofile}

  fi

done
