Having a problem getting my shell script to send an email after each row.

mgsmith7475 · 04-27-2009, 01:57 PM

I am using grep and also cut to dissect a file that contains this sample text.

Route,# of Stops,
DistpatchTime,ReturnTime,Miles,Cases,Backhaul,Driver,Email addresss alias
364,4,02:00 Wed,11:48 Wed,94,729,0,SMITH,33229
365,4,20:30 Tue,06:33 Wed,148,1270,0,BRADNER,33277
366,4,01:30 Wed,13:10 Wed,65,1211,0,BEACH,81234

I am ignoring the header field descriptions and concentrating on each of the three lines below it.
My goal here is to extract "each" comma separated value in each row, echo it out into a body of text and send a separate email using the mail command. The last field in each row represents an email alias that I plan on appending an email domain to. Essentially each line will be a separate email going to whomever.
My script works perfectly fine if I only have one row inside the text file.

I am really new at this stuff honestly.
This is what I have thus far. Any help would be very appreciated!

#!/bin/bash -vx
dos2unix /home/chiptransfer/Route.cvs
grep -v 'Route' Route.cvs 2>&1 | cut -f1,2,3,4,5,6,7,8,9 -d',' 2>&1 | sed -e 's/Wed/Wednesday/g' -e 's/Tue/Tuesday/g' >/home/chiptransfer/Step1.txt

if [ "$ROUTE" != "0" ]; then
echo " Hello Mr. $DRIVER. I am here to inform you of your scheduled rowte information for rowte number $ROUTE. Your Rowte number $ROUTE consists of $STOPNUMBERS stop numbers departing at $DISPATCHTIME and returning at approximately $RETURNTIME. The number of miles for this trip equals a grand total of $MILES miles and consisting of a total case count of $CASES.

i have a shell that does something similar.
sed -i 'ld' filename

i was using that line to strip the first line of the filename, and then looped it back around until it was finished with what it had to do.

hope that helps.

what you need is a loop something like

Code:

for rec in `cat Route.cvs`
do
    if [[ $rec =~ "Route" ]]
    then
        continue   # skip this rec and get next one
    fi
#rest of code here
done   # end of loop

You don't need to run dos2unix more than once. Newly created files will be Linux type (assuming this is run on Linux).
TBH, for something like this I'd do it in Perl, much better for this kind of munging and emailing.

I really appreciate the response! I will try this logic first thing tomorrow at work. Thanks again!!!
