Hello Friends,

I want to print string with its value from file and and again replace with new value, example below:-

cat > abc.txt
Default_user=d13703,password=az*12345

I want show "password=az*12345" and replace with "new password=az*45678".

please suggest me what to do?

Pipe cat (or grep) through cut and use comma as field delimiter (man cut).

and replace with "new password=az*45678".

You can do that with GNU sed.
