Hi Vbe,

I have done the below ...

split -l 2 line_test.txt line_test.txt
set -A TEST_ARRAY line_test.txta*
a=0
for i in ${TEST_ARRAY[@]}
do
   echo " TEST_ARRAY[$a]  : $i"
   mv $i ./line_test_$a.txt
   (( a = a + 1 ))
done

it is working ...I have searched and tried this...

But I dont know that the above is correct. Is there some nice way to do the same ?

Using an array for this is kind of overkill. If you just want to read lines one by one, read lines one by one.

A=0
while read -r LINE
do
        echo mv "$LINE" "./line_test_${A}.txt"
        let A=A+1
done < inputfile

This ought to work in any Bourne shell, while that array code will only work in KSH.

The code seems to be fine. Have you saved the file with a windows editor?

Show the input you want, the bits you want to mail, and explain what these conditions are.

Otherwise we're just guessing.

This is how my text file looks..

If the text file is more than 10 rows ,i need to divide this file and send the divided files through mail...

what i have done is the below

LINE_COUNT=`wc -l $APPLTMP/${TXT_FILE_NAME} | cut -d " " -f8`
echo "LINE_COUNT :$LINE_COUNT"
if [ LINE_COUNT -gt 10 ]
then
split -l 10 $APPLTMP/$TXT_FILE_NAME $APPLTMP/$TXT_FILE_NAME
cd $APPLTMP
set -A FILE_ARRAY ${TXT_FILE_NAME}a*
a=0
for i in ${FILE_ARRAY[@]}
do
echo " FILE_ARRAY[$a]  : $i"
#cp $i ./$APPLTMP/${TXT_FILE_NAME}_$a
(( a = a + 1 ))
done
set -A FILE_ARRAY ${TXT_FILE_NAME}a*
else
cd $APPLTMP
set -A FILE_ARRAY ${TXT_FILE_NAME}
fi
#
for i in ${FILE_ARRAY[@]}
do
#echo "inside for loop"
#
echo "  $i"
    if [ -f $APPLTMP/$i ] 
    then
(echo "Please find attached your requested report"
        uuencode ${i} ${i}) | mailx -s "${i}" ${P_EMAIL}
    fi
done

Thanks in advance..
