The return code mapping 2 was helpful. OK got that.
$# is not the return code, $# is the number of arguments.

Quote:
export BASE_FILE=$1 export DUMP_FILE=$2 export BASE_NUMBER=`head -1 ${BASE_FILE}`I still couldn't understand how these variables run into place.
$1 is the first argument, base.txt. $2 is the second argument, dump.txt. BASE_NUMBER is the first line from base.txt

Quote:
Code:
if [ `grep -c BINGO ${DUMP_FILE}` -gt 0 ]

Cool, got that.
I'd rewrite that as if grep -l BINGO "${DUMP_FILE}" >/dev/null, no need to count lines, just use grep's return code.
