read variable from file is out of alignment and extra line
!/bin/bash
FILES=/tmp/files.txt
FIELDNAME=/tmp/fieldname.txt
num=$(wc -l < $FIELDNAME)
to read fieldname.txt content
FILE1=$1
cat $FILE1 > FILE2
value=$(
to create empty lines
yes '' | sed $numq >> $FILES
to add fieldname content into files.txt
I=0
for fieldname in $value
do
echo "Line number $((I++)) --> $fieldname"
sed -i -e "iinput $fieldname " $FILES
sed -i -e 's/^/ /' $FILES
#to remove empty lines
sed -i '/^[[:space:]]*$/d' $FILES
done
sed -i '/^[[:space:]]*$/d' $FILES
my script name is script.sh and this is how I call my script:
./script.sh fieldname.txt
The expected result would be:
input abc
input def
input ghi
But the output I get is out of alignment and more than 3 lines like below:
input ghi
input def
input ghi
input abc
input ghi
input def
input ghi
input abc
input ghi
input def
input ghi
input abc
Any help would be appreciated. thanks.
