programming logic required


Guys,

I need some help here. I have a directory which has "x" no of files.

For each file it has data separated by "," !!! wow !! that is nice , we got delimiter now that makes life easy !!!
Now all what I want to do is any row(each row has 6 fields separated by ",") if it has 3 rd field as "abcdefgh" then I want to send that file as an attachment to user.

I have implemented the logic but it seems it send emails(spam) but all i want is just one email with that file(sending with uuencode).

Here is the code.

Code:
cd $BASE_DIRECTORY

for i in $(find $BASE_DIRECTORY -type f -mtime -7)
do
while IFS="," read -r rec1 rec2 rec3 _
do
if [[ "$rec3" == "abcdefgh" ]]; then
        echo -e "$i is the requested file"
        uuencode $i $i|mailx -s "Invalid record $i file" test@testme.com
else
        echo "file $i is fine and does not need to sent"
fi
done<$i
done

I prefer using 'mpack':
Code:
#!/bin/sh --
# Set debug mode when testing:
# set -vx
# Set default behaviour:
LANG=C; LC_ALL=C; export LANG LC_ALL
[ -z "${BASE_DIRECTORY}" ] && exit 127; cd "${BASE_DIRECTORY}" || exit 127
find "${BASE_DIRECTORY}" -type f -mtime -7|while read ITEM; do
 RES=$(awk -F',' '{if ($3 == "abcdefgh") print}' "${ITEM}")
 [ ${#RES} -eq 0 ] || mpack -s "Invalid record in \"${ITEM}\"" \
  "${ITEM}" test@testme.com
done
exit 0

grep -l <pattern> <filelist> will give you the name of those files, pattern will look like:
^[^,]*,[^,]*,abcdefgh,

sorry, I have no time to test it, but probably something like this:
Code:
grep -lR <pattern> "${BASE_DIRECTORY}" | xargs -n 1 send_mail
function send_mail
{ 
    uuencode $1 $1|mailx -s "Invalid record $1 file" test@testme.com

}

Don't have, can't find or not allowed to install?

Sure:
Code:
# This is just a hedge as some tools tend to produce unexpected output if those environment variables are set differently:
LANG=C; LC_ALL=C; export LANG LC_ALL
# If the variable is empty then exit with a distinctive exit value:
[ -z "${BASE_DIRECTORY}" ] && exit 127
# If we can't cd into that directory then exit with a distinctive exit value:
cd "${BASE_DIRECTORY}" || exit 127
# Most of the time using a "while" loop is preferable [0]:
find "${BASE_DIRECTORY}" -type f -mtime -7|while read ITEM; do
 # Using the comma as separator check the third value for that string
 # and fill the variable with it.
 RES=$(awk -F',' '{if ($3 == "abcdefgh") print}' "${ITEM}")
 # if the variable isn't empty then do something with it:
 [ ${#RES} -eq 0 ] || mpack -s "Invalid record in \"${ITEM}\"" \
  "${ITEM}" test@testme.com
done
# Always exit nicely:
exit 0

You could simply?
Code:
if [ "${CONDITION}" = "match_this_condition" ]; then
 echo "Urgent message" | mail -s "Urgent" test@testme.com[B]
 exit 1
fi
