how to add string inside the file's content
Hi,

How to add string inside the file. In this case adding 63 in the beginning of each line. Thnks.

e.g. what is inside the file

Code:
Mobile Number Portability
 
9051151234
9051261345
9051393245
9051412345
9051507654

Code:
Mobile Number Portability
 
639051151234
639051261345
639051393245
639051412345

Try something like this

sed 's/\(^[0-9]\)/63\1/' <file>

Alternatively,
Code:
sed '/^[0-9]/s/^/63/' infile

The AWK way:
Code:
awk '/^[0-9]+/ { print "63"$0; next } { print }' infile

Find all lines starting with a number, place that in buffer one. Then write 63 followed by buffer one

Quote:
sed 's/\(^[0-9]\)/63\1/' <file>
Find all lines starting with a number and replace the start of line with 63

Quote:
sed '/^[0-9]/s/^/63/' infile
Find all lines starting with one or more numbers, print 63 then the number
Quote:
awk '/^[0-9]+/ { print "63"$0; next } { print }' infile

Code:
#!/bin/bash

while read -r LINE
do
   case "$LINE" in
     [0-9]* ) LINE="63${LINE}"
   esac
   echo "$LINE"
done < "myfile"
