Insert character at specific location in a each line of the file
Hi All,
I am trying to write a shell script where it should insert character 'I' in 180th position of each line(except first and last line) of the file. Below is the script
Code:
for file in /home/test/bharat/*.RET
do
# Process file
echo "File Name=" $file
#l_fileName="${file##*/}"
l_fileName=`basename ${file}`_P
mv $file $l_fileName
echo "New File Name= " $l_fileName
#Remove special chracters from the file
sed 's/[!@#\$%^&*()]//g' $l_fileName>$file
mv -f $l_fileName /home/test/bharat/archive
#Loop throguh all the lines in the file and insert I in 180 position
COUNT=0
while read -r line; do
COUNT=$(( $COUNT + 1 ))
echo "line " $line
echo "Inside the file line count: " $COUNT
sed 's/./I/180' $line
done < $file
done
Somehow sed 's/./I/180' $line is not working properly. Please help to achieve this. and also i need to do this starting line 2 and should exclude last line.
Please help.
Thanks
Bharat
