- Using "$" as the regex and a count of 1 prevents empty reports from being sent. The count can be changed to 2 if the report has a header line even when it has no results.
- A specific condition can be matched, for example using a regex of "Match this text" to email the report only if the text appears in the report.
As always, there are multiple ways of solving the problem. This was a quick an convenient script to allow multiple reports to be checked and mailed to different recipients under different conditions.
# Shell script for checking a named (text) report for a number of occurrences of a
# search if the search string is found at least the number of times specified then
# the report is mailed to the specified email list
# Usage example:
# This command will check the report.csv report for any entries ($REPORT_DIR needs
# to be set):
# ./check_report.sh report.csv "$" 1 my.email@address "Email Subject"
if [ -e $1 ]; then
COUNT=`grep -c "$2" "$1"`
if [ $COUNT -gt $3 ]; then
